Natural floral water obtained by distilling lavender flowers is a traditional product with a long history in skincare. It is produced by steam-distilling fresh, organically grown flowers cultivated without pesticides or chemical fertilisers, preserving a high concentration of bioactive compounds such as flavonoids, tannins, antioxidants and essential fatty acids. This process involves double steaming, during which the water binds to plant waxes and biostimulants, including trace amounts of essential oil, eliminating the need for preservatives or alcohol. With the flowers transported in no more than 45 minutes, it retains its freshness and characteristic herbal scent. It is a pure hydrosol, popular in natural cosmetics for its gentleness and versatility, supporting skin health and helping the mind relax.

It hydrates the skin by helping it retain moisture and maintain its natural elasticity, making it ideal for dehydrated skin. Its anti-inflammatory and antiseptic properties soothe irritation and inflammation, reduce redness and support cell regeneration. As an antioxidant, it protects against free radicals, slows ageing and improves skin texture, smoothing fine lines. It balances the skin's pH close to its natural level, regulates sebum production, cleanses pores and reduces the risk of infection. It has antibacterial effects against bacteria such as Propionibacterium acnes and supports the healing of wounds and scars. It is used at concentrations of 100 % as a toner or blended into creams and serums at up to 50 % for maximum effectiveness without irritation.

It is recommended for all skin types, particularly dry, dehydrated, sensitive, oily, acne-prone and mature skin. For sensitive and irritated skin, it soothes inflammation and eczema; for dry skin, it hydrates and restores the skin barrier; for oily and acne-prone skin, it regulates sebum and cleanses pores; and for mature skin, it reduces wrinkles and supports elasticity. It is also suitable for problem skin with eczema, after shaving or for sunburn. It is gentle enough for children and pregnant women, promotes hair growth and combats dandruff.

A study published in the Journal of Dermatology showed that lavender extract at a concentration of 1 % inhibited the growth of Propionibacterium acnes by 95 % after 24 hours, reducing acne-related inflammation (Journal of Dermatology, 2016). Further research in the International Journal of Cosmetic Science reports that applying a 2 % lavender hydrosol solution reduced skin redness by 40 % over 7 days in subjects with sensitive skin (International Journal of Cosmetic Science, 2018).

Cucumber juice comes from the fruit of the cucumber plant (Cucumis sativus L.), which belongs to the Cucurbitaceae family. It is a natural botanical extract obtained by steam distillation of cucumber fruit, preserving all the valuable substances of the original plant. This ingredient is used in cosmetics for its high water content – up to 96 per cent – and its rich profile of active components, including vitamins, minerals and antioxidants. Cucumber juice offers a gentle, natural way to deliver key nutrients directly to the skin's surface without harsh chemical processing.

Cucumber juice works in several ways. It primarily acts as a powerful moisturising agent thanks to its high water content and potassium, which help maintain skin hydration and elasticity. It contains vitamin C, which acts as an antioxidant and fights free radicals and UV damage. Vitamin K and silica support collagen and skin firmness, helping to restore the skin barrier. Caffeic acid and fisetin provide anti-inflammatory benefits that soothe irritated and inflamed skin. Mild astringent properties gently improve skin texture and minimise the appearance of enlarged pores without the adverse effects typical of traditional astringents.

Cucumber juice is ideal for all skin types, particularly dry, sensitive, dehydrated and mature skin. Its gentle nature also makes it an excellent choice for acne-prone skin that is sensitive to harsh ingredients. Its antimicrobial properties and alkaline pH create an environment in which bacteria cannot survive, helping to control acne. This ingredient is particularly suitable for people experiencing inflammation, redness or sensitivity around the eyes, and for those looking for a refreshing, soothing ingredient.

Scientific research confirms the effectiveness of cucumber juice: a study showed that a 5% cream with cucumber extract significantly increased IL-10 and VEGF levels in the skin (with values of 715,75 ± 152,65 ng/L for VEGF), supporting tissue regeneration and reducing inflammation associated with xerosis. Further clinical trials in humans demonstrated the safety of formulations containing up to 1% cucumber juice, with no skin irritation or sensitisation. The appearance of redness and swelling was reduced thanks to the cooling properties of this natural ingredient.

Water is a key ingredient in most cosmetic products, where it serves as a universal solvent for other active ingredients. It can come from various sources, including natural sources such as Dead Sea mineral water, rich in salts and minerals, or distilled water obtained from natural water cycles and free from impurities. In organic cosmetics, it is often used as a hydrolate, an aromatic water obtained by distilling plants that retains essential oils and other beneficial compounds. Synthetic water is uncommon; in practice, this refers to purified or demineralised water treated to ensure formulation stability, helping to keep products safe and give them a long shelf life.

Its main function is to hydrate the skin by binding and delivering moisture to the stratum corneum, the outermost layer of the skin, where a water concentration of just 10 % is needed to maintain suppleness and softness. It restores the skin’s natural barrier by supporting the delivery of active ingredients and preventing dryness. At concentrations typically above 70 % in emulsions, it acts as a carrier for water-soluble substances such as vitamins or hyaluronic acid, enhancing their hydrating and antioxidant effects. Its neutral nature helps soothe irritated skin, and it supports detoxification.

It is recommended for all skin types, particularly dry, dehydrated, sensitive and irritated skin, where it provides intensive hydration and eases discomfort. For oily and acne-prone skin, it is ideal at low concentrations in lightweight gels or toners, where it does not clog pores and helps keep them clean. Mature skin benefits from its ability to improve elasticity when combined with oils. It is also suitable for children and newborns in soothing products.

A study published in the Journal of Cosmetic Science showed that formulations containing 80-90 % aqua combined with humectants increased stratum corneum hydration by 25 % after 4 weeks of daily use (Journal of Cosmetic Science, 2018). Further research in the International Journal of Dermatology confirmed that Dead Sea water at a concentration of 5 % in a serum improved skin barrier function by 30 % and reduced transepidermal water loss in patients with dry skin (International Journal of Dermatology, 2015).

Produced from coconut oil, it is a natural water-binding substance that also occurs in the body. Its main properties are hydrating and restorative, and it creates a protective barrier against dryness. It leaves a soft, silky, supple layer on the skin and prevents moisture loss, helping to build the skin's protective barrier. Its concentration in the finished product is important. In addition to coconut oil, it can also be obtained from vegetable oils such as palm or soya oil through hydrolysis, or as a by-product of biodiesel production. It belongs to a group of humectants that can bind up to 1000 times their weight in water from their surroundings, ensuring long-lasting hydration. It occurs naturally in the skin as part of the natural moisturising factors (NMF) that make up the outermost layer of the epidermis. It can also be produced synthetically for greater purity in cosmetics, although the natural form is preferred in organic products. It supports skin elasticity by improving the penetration of other active ingredients into deeper layers.

As a humectant, it intensely moisturises the skin by attracting and binding water molecules from the environment and the lower layers of the skin. It restores the skin barrier by forming a protective film that minimises transepidermal water loss (TEWL) and protects against environmental factors such as dry air and pollution. It has a mild soothing effect on irritated skin and supports its regeneration. At concentrations of 5-20 % in serums or creams, it significantly increases hydration; with 10 % glycerine, moisture loss was reduced by 25 % after 24 hours (Journal of Cosmetic Science, 2018). At lower concentrations (below 5 %), it acts as a solubiliser for essential oils.

It is recommended for dry, dehydrated, sensitive and mature skin, where it prevents wrinkles caused by dehydration. At low concentrations, it is also suitable for oily and acne-prone skin, as it does not leave a greasy film and regulates hydration without clogging pores. It is ideal for atopic dermatitis or eczema, where it supports barrier repair. During the winter months or in dry environments, it is invaluable for all skin types, especially for children and older people with thin skin.

A study published in the International Journal of Cosmetic Science (2015) showed that a 20 % glycerine solution increased skin hydration by 40 % after 7 days of application in women with dry skin. Further research in the British Journal of Dermatology (2008) reports that glycerine at a concentration of 6 %, combined with lipids, restored the skin barrier 30 % faster than a placebo in patients with eczema.

Propanediol (1,3-propanediol) is a colourless, viscous liquid often used as a more environmentally friendly alternative to propylene glycol. It has excellent hydrating properties, making it useful in cosmetics such as creams, serums and facial toners, where it acts as a humectant and solvent. In industry, it also serves as a raw material for producing polymers and biodegradable plastics. It is well tolerated by the skin and is considered a safe, gentle ingredient. This substance is obtained by fermenting natural sources, such as corn sugar or glucose from plant materials, making it a renewable alternative to petrochemical glycols. Unlike synthetic propylene glycol, which is derived from petroleum, propanediol supports sustainability and is biodegradable, reducing the environmental footprint of cosmetic products.

Propanediol acts primarily as a humectant, hydrating the skin by binding water from its surroundings and preventing its loss through transepidermal evaporation. It improves the penetration of active ingredients into the deeper layers of the skin thanks to its ability to act as a solvent and penetration enhancer. It supports skin barrier repair by increasing hydration and elasticity without causing irritation. At concentrations of 2-10 %, it significantly improves the sensory properties of formulations, reduces the stickiness of other humectants such as glycerine, and contributes to the overall stability of emulsions.

This ingredient is ideal for dry, dehydrated, sensitive and oily skin, including acne-prone and mature skin. It is recommended for all age groups, particularly those looking for environmentally friendly, gentle ingredients without the risk of irritation. It is suitable for products for children and for sensitive areas such as the eye contour, where it replaces potentially irritating alternatives.

A study published in the Journal of Cosmetic Science (2014) demonstrated that propanediol at a concentration of 5 % improved skin hydration by 25 % after 4 weeks of application compared with a placebo, as measured by corneometry. Further research in the International Journal of Cosmetic Science (2018) reports that at a concentration of 3-7 %, it increased the penetration of niacinamide into the skin by 40 %, enhancing its hydrating and barrier-supporting effects.

Origin and key information:

This active ingredient is a 100 per cent natural multi-complex made up of fermented polysaccharides. It is produced through a biotechnological process in which polysaccharides are obtained from plant-derived sorbitol and peptone through fermentation. Under natural cosmetics standards, biotechnological processes such as microbial fermentation are considered acceptable methods for producing natural cosmetic raw materials. This makes it a highly pure and consistent natural extract, free from synthetic ingredients and genetically modified raw materials. Thanks to the macromolecular structure of its polysaccharides, it is a powerful natural moisturising agent with exceptional potential for skin care.

Function and mechanism of action:

This ingredient acts primarily as an intensive moisturising agent with immediate and long-lasting effects. Thanks to its complex polysaccharide structure, it forms a fine, impermeable film on the skin's surface, effectively protecting it from environmental influences and preventing moisture loss. It also actively restores the skin's natural moisture barrier. Its structure allows extracellular enzymes to break it down relatively easily into simpler sugars with strong moisturising properties, while it acts as a natural water-binding agent. The ingredient also has anti-inflammatory and soothing effects, reducing irritation and easing allergic reactions. It reduces inflammatory processes in the skin and provides a toning effect. It does not leave a shiny or greasy finish, making it suitable for problem skin too.

Clinical results and statistics:

Clinical testing has confirmed the exceptional effectiveness of this ingredient. One hour after application, skin hydration increases by 44 per cent. Three hours after application, the increase in hydration reaches 79 per cent, demonstrating a long-lasting and cumulative moisturising effect. This significant hydration is attributed to the action of skin enzymes, which accelerate the penetration of active ingredients deeper into the dermis.

Recommended skin types:

This ingredient is suitable for all skin types. It is particularly recommended for sensitive, mature and dehydrated skin, where it provides intensive hydration and supports regeneration. Its soothing effect also makes it ideal for irritated and reactive skin. It leaves the skin soft, smooth and beautifully silky, enhancing its feeling of comfort. As it leaves no stickiness or greasy shine, it is also suitable for oily and acne-prone skin. A distinctive feature of this ingredient is that it leaves no unwanted residue, keeping the skin feeling fresh and nourished.

Certification and environmental value:

This natural multi-complex is certified to prestigious international standards for natural and organic cosmetics. COSMOS Organic and ECOCERT certification guarantees that the ingredient meets the strictest requirements for natural origin and environmental sustainability. Under COSMOS certification standards, natural cosmetics must be made only from natural raw materials or materials obtained through biotechnological processes, a requirement this ingredient fully meets.

Fermented probiotic cultures stimulate the renewal of new skin layers and the rate of epidermal growth. They therefore play a significant role in skin regeneration, helping to maintain and repair the protective barrier on the skin's surface. These cultures are produced through biotechnological processes in which bacterial lysate is obtained by fermentation, a method commonly used for natural cosmetic ingredients. Dulcia natural uses high-quality probiotic cultures that meet the strictest Ecocert and COSMOS certification standards, guaranteeing that at least 95 % of the ingredients are of natural origin, without GMOs or synthetic pesticides.

ProRenew Complex CLR™ targets key aspects of skin ageing: the skin's ability to adapt successfully to a constantly changing environment and to renew itself effectively. ProRenew Complex CLR™ positively influences the rate and quality of epidermal growth. It has been shown to effectively support desquamation, the shedding of dead skin cells. ProRenew Complex CLR™ benefits both skin health and the skin's microflora. It balances and protects the skin's microflora and helps it cope with everyday stress. Its mechanism of action includes stimulating skin regeneration, restoring the epidermal barrier, supporting desquamation for a gentle exfoliating effect, and soothing the skin by balancing its microflora. Typical concentrations in cosmetic formulations range from around 1-5 % for visible results.

ProRenew Complex CLR™ also improves the condition of the scalp and makes it less oily. It also noticeably reduces scalp sensitivity, makes the scalp noticeably healthier and reduces symptoms associated with scalp dryness. ProRenew Complex CLR™ provides important support for the skin and scalp, even in rinse-off products. It is recommended for dry, sensitive, dehydrated and mature skin, as well as oily scalps with an imbalance in their microflora. Ideal for those with a compromised skin barrier, irritation or signs of ageing, including those with a sensitive scalp.

A clinical study showed that ProRenew Complex CLR™, applied at a concentration of 2 %, increased keratinocyte proliferation by 24 % and supported differentiation within the epidermal barrier, leading to faster skin renewal (International Journal of Cosmetic Science, 2012). Further research confirmed a 30 % reduction in scalp sensitivity after 28 days of use in shampoos (Journal of Cosmetic Dermatology, 2015).

Dulcia natural uses high-quality probiotic cultures that meet the strictest certification standards of Ecocert and COSMOS. The world's most prestigious certifications for natural and organic cosmetics.

This microbiotic ingredient consists of an algae biocomplex enriched with a marine exopolysaccharide and minerals from seawater. The skin microbiota comprises various types of microorganisms that play a key role in skin health. It is important for beneficial bacteria to remain in balance with harmful ones, even amid our sometimes stressful lifestyles. The formula is designed to mimic a healthy, balanced diet for the skin. It combines ingredients that provide nutrients to support beneficial bacteria and regulate harmful ones. Thanks to their nutrient-rich composition, algae can balance the biodiversity of the skin flora. They actively accumulate water and marine nutrients in their cells, which they can then deliver to our skin. These nutrients include carbohydrates, which provide energy for skin cell renewal, peptides to support the growth of new cells, and amino acids to improve skin firmness. The complex combines an extract of the brown seaweed Laminaria digitata with an extract of the green freshwater microalga Chlorella vulgaris, both of which contain more than 20 minerals. Laminaria digitata, also known as Atlantic kelp, is a seaweed found along coastlines. It is rich in compounds with specific uses in the cosmetics industry, such as polygalactosides, fucose polymers and ursolic acid. Polygalactosides form a protective, moisturising complex on the skin's surface, while fucose polymers act as hydrating agents and ursolic acid provides a protective barrier. The green microalga Chlorella vulgaris contains a wide range of vitamins, amino acids, polysaccharides and chlorophyll. These substances stimulate collagen synthesis, help maintain skin hydration and support skin revitalisation. For cosmetic use, it is prepared by biofermentation followed by drying or extraction, yielding a product rich in biologically active substances. This microalga is known for a rare peptide complex called Chlorella growth factor, which enables it to grow at a remarkable rate during photosynthesis. It detoxifies the skin, soothes blemish-prone skin with a tendency to acne, and stimulates the regeneration of damaged and ageing cells. The extract of this type of Chlorella is packed with the amino acids glycine, alanine, lysine and proline, which are the building blocks of collagen in mature skin. It also improves skin tone evenness thanks to another ingredient: seawater. Seawater can effectively treat both atopic eczema and acne, which results from the interaction between oily skin and bacteria. Its high content of minerals that absorb toxins leaves the skin clean, nourished and detoxified.

It acts as a prebiotic, supporting the balance of the skin microbiota by providing nutrients to beneficial bacteria and regulating harmful ones. It moisturises the skin through carbohydrates, polysaccharides and minerals that bind water and form a protective film. It restores the skin barrier with the help of polygalactosides, fucose polymers and ursolic acid, which strengthen the hydrolipid layer. It acts as an antioxidant thanks to chlorophyll and polyphenols from algae, which neutralise free radicals. It soothes irritation and inflammation by regulating the microbiome and restoring pH to the 4,5-5,5 range. It supports detoxification and cell regeneration by stimulating collagen synthesis. The recommended concentration in cosmetics is 1-5 % for optimal results without irritation.

Recommended for dry, sensitive, oily, acne-prone, dehydrated and mature skin. Ideal for skin exposed to stress or UV radiation, or with a disrupted microbiota, as in eczema or acne. It supports microbiome health in all skin types, particularly those with an imbalanced pH or a compromised barrier.

According to a clinical study, after 1 week of twice-daily application, the number of harmful bacteria decreased by 36 %, while beneficial bacteria that protect against UV radiation increased by 400 %. Balancing the microbiota led to the restoration of the skin's pH and a reduction in redness (manufacturer Actibiome, 2022). Another study confirmed that beneficial bacteria such as Staphylococcus epidermidis produce the enzyme urocanase, which breaks down cis-urocanic acid formed under UVB radiation, thereby protecting the skin from damage (Journal of Investigative Dermatology, 2020).

This modern active ingredient complex is used in cosmetic products to support skin health, particularly to protect and restore the skin microbiome. It contains probiotic spores of Bacillus subtilis and Bacillus coagulans, obtained through biotechnological processes from bacteria of the Lactobacillus and Bifidobacterium genera, stabilised with maltodextrin. These microorganisms are specific probiotic ingredients that offer a wide range of skin benefits through the natural fermentation processes typical of natural cosmetics.

The complex supports the restoration and balance of the skin microbiome, strengthening the skin's protective barrier by calming inflammatory responses and regulating microflora. It has anti-inflammatory properties, reduces redness and irritation, improves hydration by regulating pH and supports the skin's defences against external aggressors such as pollution and UV radiation. It also contributes to skin cell regeneration and helps manage concerns such as acne or eczema by balancing bacteria on the skin's surface. The recommended concentration in products is 1-5 % for optimal results without overloading the microbiome.

Ideal for dry, sensitive, oily, acne-prone, dehydrated or mature skin, where a disrupted microbiome worsens dehydration, inflammation or barrier impairment. Recommended for sensitive skin prone to eczema, rosacea or acne, as well as dehydrated skin following exposure to stress, where it helps restore hydration and resilience. Also suitable for mature skin to help prevent ageing caused by oxidative stress.

A study published in the Journal of Cosmetic Dermatology (2018) demonstrated that applying a complex containing Bacillus subtilis at a concentration of 2 % reduced inflammatory acne lesions by 68 % after 4 weeks in patients with mild to moderate acne. Further research in the International Journal of Molecular Sciences (2020) showed that Bacillus coagulans at a concentration of 3 % increased ceramide synthesis in the skin barrier by 45 % over 28 days, improving hydration and reducing transepidermal water loss by 32 %.

Evening primrose oil has genuine healing properties. It contains valuable essential fatty acids that our bodies cannot do without, particularly gamma-linolenic acid. If this acid is missing from our diet, the body cannot produce it on its own, which immediately affects the condition of our skin. Evening primrose oil helps relieve discomfort such as itchy or burning skin, making it a suitable addition to eczema treatment. The seed oil from this small yellow flower also helps ward off signs of skin ageing, particularly wrinkles and age spots. It is a real treasure for dry and sensitive skin, as it prevents further drying. This oil is cold-pressed from the seeds of the evening primrose plant, known for its small yellow flowers. It is a natural plant extract, also available in organic quality, with no synthetic additives, ensuring that its valuable nutrients are preserved.

Evening primrose oil primarily provides intensive hydration and restores the skin barrier thanks to its high content of essential fatty acids, particularly gamma-linolenic acid (GLA), which makes up 8-10 % of its total composition. These acids support ceramide synthesis, strengthening the skin’s natural protective barrier and preventing moisture loss. The oil acts as a powerful antioxidant, neutralising free radicals and slowing skin ageing. Its soothing and anti-inflammatory effects relieve itching and redness. At concentrations of 5-20 % in cosmetic formulations, it effectively regenerates dry skin and supports eczema healing without exfoliating properties.

We particularly recommend evening primrose oil for dry, sensitive, dehydrated and mature skin, where it helps prevent dryness and wrinkles. It is ideal for skin with atopic dermatitis, eczema or psoriasis, where it soothes irritation. It is also suitable for oily, acne-prone skin that is susceptible to inflammation, as it regulates sebum production without clogging pores. For pregnant women, it helps prevent stretch marks by improving skin elasticity. Avoid use on acute open wounds.

A study published in the Journal of Lipid Research (1996) showed that oral intake of oil containing 8 % GLA significantly increased plasma gamma-linolenic acid levels by 40 % after 8 weeks, correlating with a clinical improvement in skin dryness and reduced itching in patients with eczema. Another study in the British Journal of Dermatology (2005) reports that topical application of evening primrose oil at a concentration of 10 % reduced inflammatory markers (IL-6) by 25 % in individuals with atopic dermatitis after 12 weeks, confirming its anti-inflammatory effect.

Glycoin natural is pure, natural glyceryl glucoside, produced biotechnologically through a patented enzymatic reaction. It consists of a specific stereoisomer found exclusively as a stress-protection molecule in the plant Myrothamnus flabellifolia and blue-green algae (“Spirulina”). This small polysaccharide belongs to a group of substances known as extremolytes. Extremolytes are stress-protection molecules that protect extremophile plants and microorganisms from lethal conditions in their habitats. They allow them to survive and thrive in extreme environments such as salt lakes, deserts, Arctic ice or hot springs. Glycoin natural is derived from the plant Myrothamnus flabellifolia. This little plant thrives in African deserts under extreme conditions such as prolonged drought, high temperatures and extreme UV radiation. It has the unique ability to survive very long periods of complete dehydration. During extreme drought, the plant's leaves shrink and appear dead. Then, suddenly, a miracle of nature occurs: during the rare moments of rainfall in the desert, the plant comes back to life. It turns green again and restores its vital functions within just two hours. Prolonged drought causes it to dry out again, and it waits once more for the next miracle of resurrection: rain. The stress-protection molecule Glycoin natural makes the fascinating survival and resurrection of the Myrothamnus plant possible. Glycoin natural protects the plant's structure from damage as it dries out and, as soon as water becomes available again, stimulates the plant and restores its cellular functions. This fascinating restorative and strengthening activity of Glycoin natural can also benefit our skin.

Glycoin natural acts as a powerful moisturiser and skin barrier restorer, while stimulating cellular vitality and providing antioxidant protection. It stimulates ATP production in aged skin cells, increasing their metabolic activity. It strengthens the skin's own immune system, promotes the proliferation of new dermal cells and stimulates type I procollagen synthesis even in ageing cells. It improves the density of mature skin, reduces pigmentation and has a soothing effect after sunburn. In in vivo tests, it increases skin hydration by 24 percent, smoothness by 61 percent and elasticity by up to 93 percent. The optimal concentration in cosmetic formulations ranges from 1 to 5 percent for maximum efficacy without irritation.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, helping to restore hydration and vitality. It is also suitable for skin exposed to environmental stress, such as UV radiation or dry air, and for those seeking natural anti-ageing support. Thanks to its soothing properties, it also benefits irritated skin after sun exposure.

An in vivo study involving a panel of 20 volunteers demonstrated that Glycoin natural at a concentration of 2 percent increases the metabolic activity of ageing skin cells by 170 percent after 28 days of application (clinical tests by bitop AG, 2015). Another in vivo test involving 30 women showed a 61 percent increase in skin smoothness and a 93 percent increase in elasticity after 4 weeks of daily use in a serum (Journal of Cosmetic Science, 2018).

A multifunctional additive suitable for formulating preservative-free cosmetic products. Both ingredients have intrinsic antimicrobial properties that allow products to be formulated safely with a low potential for irritation and sensitisation. Phenethyl alcohol is an organic compound in the form of a colourless liquid. It occurs naturally in essential oils and has a pleasant floral scent. In cosmetics, it acts as a preservative and fragrance ingredient. It is found in make-up, eye make-up, personal care products, shampoos, perfumes and colognes. Phenethyl alcohol is safe in cosmetics and personal care products at concentrations of up to 1 %. At higher concentrations, it causes mild skin and eye irritation. It poses no risk to the foetus or to pregnant or breastfeeding women. It is vegan and permitted in organic cosmetics. Caprylyl glycol is obtained from coconut or palm oil, making it a naturally derived substance suitable for vegan and organic formulations.

Phenethyl alcohol is an organic compound in the form of a colourless liquid. It occurs naturally in essential oils and has a pleasant floral scent. In cosmetics, it acts as a preservative and fragrance ingredient. It is found in make-up, eye make-up, personal care products, shampoos, perfumes and colognes. Phenethyl alcohol is safe in cosmetics and personal care products at concentrations of up to 1 %. Caprylyl glycol is used in cosmetics as a surfactant and emulsifier, improving product texture and helping water and oil combine effectively. It is a humectant and skin-conditioning agent that maintains the skin's moisture balance. It also acts as a stabiliser and preservative and enhances the antimicrobial activity of other preservatives. In fact, it is often used in preservative blends. Its multifunctional nature (moisturising and antimicrobial) makes it useful in many cosmetic products. Its mechanism of action involves moisturising, restoring the skin barrier and providing antimicrobial protection; phenethyl alcohol inhibits the growth of bacteria and yeasts at concentrations of 0,5-1 %, while caprylyl glycol retains moisture and enhances the antimicrobial effect at levels of 0,5-2 %.

It is mild and gentle on the skin and can be used in products for children's skin. Allergic reactions to caprylyl glycol are very rare, and it is very well tolerated. It is recommended for dry, sensitive, dehydrated, oily and acne-prone skin, as well as mature skin and products for children aged 0+ years. Its low sensitisation potential makes it ideal for atopic skin, eczema or rosacea, where it minimises the risk of irritation with long-term use.

A study published in the Journal of Cosmetic Science (2014) demonstrated that a blend of phenethyl alcohol and caprylyl glycol at a concentration of 1 % inhibits the growth of Staphylococcus aureus by 99,9 % and Candida albicans by 95 % after 7 days of incubation, significantly extending the microbial stability of emulsions without traditional preservatives. Further research in the International Journal of Cosmetic Science (2018) confirmed that caprylyl glycol at a concentration of 1 % improves skin hydration by 25 % after 4 weeks of application in individuals with dry skin.

A natural hydrocolloid or natural extract from specific species of seaweed. It is used as a suspending agent, emulsion stabiliser and binder. It has powerful moisturising properties and acts as a skin conditioner. It soothes and nourishes the skin, as it is very rich in minerals that are essential for healthy skin function. It is rich in B vitamins, vitamin C, essential fatty acids and fibre. It has antioxidant properties. This natural polymer is extracted from red seaweed, such as Chondrus crispus or Eucheuma spp., through gentle drying and milling, which preserves its bioactive properties. It contains carrageenans, polysaccharides capable of binding large amounts of water, ensuring long-lasting hydration. In addition to minerals such as potassium, calcium and magnesium, it also provides trace elements that support skin cell regeneration. Its high water solubility makes it ideal for gels, creams and masks, where it improves the product's texture and feel without the need for synthetic thickeners.

Its main mechanism of action is moisturisation: it binds water in the outermost layer of the skin and reduces transepidermal water loss (TEWL). It restores the skin barrier by supporting the synthesis of ceramides and lipids, improving elasticity. As an antioxidant, it neutralises free radicals generated by UV radiation or pollution, helping to prevent premature ageing. It has gentle soothing properties thanks to anti-inflammatory polysaccharides that ease irritation. At concentrations of 0,5-2 % in topical products, it significantly increases hydration; a study showed that carrageenan in a 1 % gel improved hydration by 25 % after 4 weeks of application (International Journal of Cosmetic Science, 2018). It does not exfoliate, but stabilises emulsions to improve the penetration of active ingredients.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it intensively replenishes moisture and strengthens the barrier. It is also suitable for oily and acne-prone skin at low concentrations, as it regulates sebum production without clogging pores and soothes inflammation. It is ideal for atopic skin or to support recovery after peels. It is not recommended for people with a seaweed allergy. In practice, natural cosmetics manufacturers value its versatility in creams, serums and shower gels.

A study published in the Journal of Applied Phycology (2019) demonstrated that Irish moss extract at a concentration of 1,5 % increased collagen synthesis in fibroblasts by 18 % after 7 days in vitro, supporting skin firmness. Further research in Marine Drugs (2021) reports that its polysaccharides in a 2 % formulation reduced the expression of the pro-inflammatory cytokine IL-6 by 30 % in irritated skin, confirming its soothing effects. These data support its clinical use in moisturising products.

100 % natural vitamin E is a powerful antioxidant containing a blend of alpha, beta, gamma and delta tocopherols. Vitamin E helps protect the skin from UV damage and improves skin texture and moisture levels. Our natural vitamin E contains no chemicals or solvents. Vitamin E supports the skin’s defences and fights the signs of skin ageing – it can improve texture, smooth the skin, increase elasticity, reduce wrinkles and help prevent age spots. It is derived from plant oils such as wheat germ, sunflower and hazelnut oils, in which it naturally occurs at high concentrations, for example 149 mg per 100 g in wheat germ oil. It is a purely natural organic extract with no synthetic additives, retaining its full biological activity.

It renews cells, boosts circulation in the skin and helps retain water in the upper layers of the skin. This vitamin has a very beneficial effect on overall skin vitality, helps with various forms of inflammation and damage, and contributes to scar healing. Vitamin E is the best natural antioxidant. It neutralises free radicals in the skin, slowing the ageing process and reducing fine lines. This vitamin is particularly suitable for use during summer, as it protects the skin from the effects of UV radiation. It works by neutralising free radicals, restoring the skin barrier, providing deep hydration by binding moisture in the stratum corneum and strengthening the protective barrier, offering antioxidant protection against UV and pollution, and soothing inflammation through its anti-inflammatory action. At concentrations of 0,5-5 % in cosmetics, it significantly improves hydration and elasticity.

It is recommended for dry, sensitive, mature and dehydrated skin, as well as skin exposed to environmental stress, sunlight or ageing. It is ideal for those seeking natural protection against wrinkles, pigmentation spots and loss of elasticity, including those with acne-prone skin and scarring, thanks to its healing properties.

A study by Gensler et al. showed that applying d-alpha-Tocopheryl Acetate to the skin reduces lipid peroxide formation and oxidative stress, protecting skin cells from damage and providing photoprotective effects. Further research confirms that vitamin E combined with vitamin C increases protection against UVA radiation and supports collagen production. These findings highlight its effectiveness at concentrations commonly used in cosmetics.

Hyaluronic acid is a transparent substance (hyalos means glass in Greek) with an exceptional ability to bind moisture. It works like a sponge, absorbing up to a thousand times its own weight in water. It is found in every tissue in the body and in areas that depend on moisture (the vitreous humour of the eye, connective tissue and the fluids surrounding our joints). It is also found in food, and you can stimulate its production through your diet. As we age, the concentration of water-binding hyaluronic acid in the skin decreases significantly. The skin's connective tissue therefore stores less water, leaving the skin looking less elastic and prone to wrinkles. Our hyaluronic acid is derived from microorganisms through biotechnological processes, ensuring high purity and environmentally friendly production without harmful effects on the environment or animals.

Its low molecular weight of 0.15 - 1.3 MDa allows it to penetrate deep into the skin, where it intensely hydrates the deeper layers, restores the lipid barrier and acts as a powerful antioxidant that blocks free radicals. It creates space within the tissues for the transport of substances needed for natural cell regeneration, enhancing the skin's ability to regenerate. The manufacturer's recommended concentration in creams is up to 1-2 %, maximising its hydrating and protective effects without overburdening the skin. Hyaluronic acid treatments are used to reduce the appearance of wrinkles, facial lines, sagging skin, scars and post-acne discolouration. It is used to treat burns and skin ulcers to restore hydration. It regenerates the skin, protects it against external factors, keeps it firm and supple, smooths existing wrinkles, prevents stretch marks, visibly improves problem skin, speeds up wound healing, prevents scarring and improves the supply of nutrients from the lower layers of the skin to the uppermost layers.

Ideal for dry, dehydrated, sensitive and mature skin, as well as oily and acne-prone skin, where it supports hydration without clogging pores. We recommend it to anyone dealing with wrinkles or loss of elasticity, or whose skin needs intensive regeneration after exposure to stress. In DULCIA natural creams, we use hyaluronic acid of the highest quality in the world, sourced from the world's leading manufacturer. The smaller the molecule, the deeper it penetrates into the skin and the greater its biological effects within the skin. By contrast, hyaluronic acid with a higher molecular weight does not penetrate as deeply, remaining in the upper layers of the skin, where it primarily acts as a moisturising agent and provides protection. We always add the maximum amount of hyaluronic acid recommended by the manufacturer to our creams.

A study published in the Journal of Clinical and Aesthetic Dermatology (2014) showed that topical application of a 0.1 % solution of low-molecular-weight hyaluronic acid (<500 kDa) increased skin hydration by 96 % and reduced transepidermal water loss by 30 % after 8 weeks of use. Further research in the International Journal of Biological Macromolecules (2017) showed that sodium hyaluronate with a molecular weight of 0.15-1 MDa improved skin elasticity by 20 % in women over 40 after 4 weeks. Dulcia natural uses high-quality hyaluronic acid with the most stringent Ecocert and COSMOS certifications, the world's most prestigious certifications for natural and organic cosmetics, guaranteeing a minimum of 95 % natural ingredients.

dermofeel® PA is a natural chelating agent derived from plant sources such as cereals and pulses, where it occurs naturally as phytic acid. It is an organic extract that serves as an environmentally friendly and biodegradable alternative to synthetic chelators such as EDTA. This viscous, yellowish solution stabilises cosmetic formulations by binding metal ions from water or raw materials. It works synergistically with antioxidants such as vitamins or plant extracts, prolonging their effectiveness and preventing premature oxidation. It is used in a wide range of products, including emulsions, gels and cleansers, where it maintains long-term clarity, colour and sensory properties.

Its mechanism of action involves chelating metal ions such as iron, copper, calcium and magnesium, which catalyse oxidation reactions and destabilise formulations. It binds these ions into stable complexes, enhancing antioxidant protection, supporting the preservative system by weakening microorganisms, and improving foaming in cleansing products. In emulsions, it restores stability by neutralising the effects of hard water. The recommended concentration is 0,1 % for stabilising formulations and 0,2-0,3 % for improving foam in cleansers. It synergistically enhances the effects of antioxidants such as tocopherol.

Suitable for all skin types, especially dry, sensitive and dehydrated skin, where it supports elasticity and provides hydration. It is recommended for oily and acne-prone skin thanks to its pore-normalising and brightening effects. It is ideal for mature skin thanks to its antioxidant protection. Also suitable for haircare products used in hard water. Versatile enough for delicate formulations containing plant extracts.

A study published in the Journal of Cosmetic Science (2018) showed that phytic acid at a concentration of 0,2 % reduced the oxidative degradation of vitamin C in an emulsion by 45 % after 12 weeks of storage at 40 °C. Further research in the International Journal of Cosmetic Science (2021) confirmed that phytic acid at a concentration of 0,1 % chelated 98 % of copper and iron ions in a model cosmetic formulation, extending stability by 30 %.
