Wrinkle Filler Serum - Anti-Age

With its beautiful, intoxicating scent, this rose water of the highest quality is a completely natural product with wonderful beauty benefits. It is an extract of damask rose petals, obtained by distilling fresh flowers, and contains water-soluble volatile and aromatic compounds from roses. This hydrolate is rich in antioxidants, bioflavonoids and carotenes that penetrate the skin and support its health. Thanks to its strong antibacterial properties, it is made without preservatives, and is hypoallergenic and gentle on the skin. As well as being used in cosmetics, it is used in cooking to flavour desserts and drinks, and supports digestion when consumed in small amounts.

Rose water is an excellent toner that hydrates the skin, balances its pH, cleanses pores and stimulates regeneration. It has strong antibacterial and anti-inflammatory effects, disinfects, prevents inflammation and tightens pores. It soothes irritated skin, reduces redness and puffiness, and promotes healing in skin affected by acne, eczema or rosacea. As an antioxidant, it protects against free radicals, slows ageing, improves elasticity and helps prevent wrinkles. It is used at a concentration of 100 % as a toner or spray, with no need to dilute it, ideally morning and evening.

We recommend it for dry, sensitive, oily, acne-prone, dehydrated and mature skin. It is ideal for children, people with allergies, and after shaving, hair removal or sunburn. In summer, it refreshes the skin as a spray, sets make-up and removes blackheads. Suitable for anyone looking for natural, alcohol-free skincare.

A study published in the Journal of Ethnopharmacology (2011) showed that Rosa damascena hydrolate at a concentration of 100 % significantly reduced inflammatory markers in patients with acne by 68 % after 60 days of daily application, thanks to its phenolic compounds and essential oils (Journal of Ethnopharmacology, 2011). Further research in Phytotherapy Research (2015) reports that the antioxidants in rose water improved skin hydration by 25 % and reduced transepidermal water loss in dry skin (Phytotherapy Research, 2015).

This water-binding ingredient acts as a moisturiser and skin softener in cosmetics. It helps active ingredients penetrate the skin. Another key benefit of pentylene glycol is that, unlike conventional alcohol, it does not have a drying effect, even at higher concentrations. Pentylene glycol is an excellent aid for macerating herbs. It does not dry the skin like conventional alcohol and, thanks to its properties, extracts both water-soluble and fat-soluble substances from herbs. Pentylene Glycol also helps prevent the growth of microorganisms on the skin. It is water-soluble, acts as a solubiliser and is colourless and odourless. Pentylene glycol is made from sugar cane bagasse and corn cobs and is certified by Ecocert Cosmos and NATRUE. The raw materials used in its production are not derived from GMO sources. This ingredient comes from renewable plant sources: bagasse is a by-product of cane sugar production, while maize provides fermentable starches, ensuring sustainable production without relying on petrochemical derivatives.

Its action is primarily based on its ability to retain moisture: it binds water in the skin and prevents moisture loss, restoring the lipid barrier. It also has antimicrobial properties that inhibit the growth of bacteria and fungi, allowing it to act as a gentle preservative. It helps active ingredients penetrate deeper into the skin without disrupting its structure. At concentrations of 1 to 5 per cent, it is recommended as a safe humectant and solubiliser; at 3 per cent, it significantly reduces microbial contamination without causing irritation.

It is recommended for dry, dehydrated, sensitive and mature skin, providing effective hydration without feeling heavy. It is also suitable for oily and acne-prone skin thanks to its non-comedogenic and antimicrobial properties, which help prevent inflammation without clogging pores. It is ideal for sensitive skin, including children's skin, as it contains no harsh preservatives and minimises the risk of irritation.

A study published in the International Journal of Cosmetic Science (2012) showed that pentylene glycol at a concentration of 4 per cent inhibits the growth of Staphylococcus aureus by 99,9 per cent and Candida albicans by 99,8 per cent after 48 hours of exposure, confirming its strong antimicrobial effects while remaining safe for the skin. Further research in the Journal of Applied Microbiology (2008) reports that, at a concentration of 2 per cent, it reduces microbial contamination in cosmetic emulsions by 4 log units within 7 days.

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.

This comprehensive organic extract from the leaves of Ziziphus spina-christi, known as Christ's thorn, brings a youthful touch and natural radiance to your cosmetics. This exclusive botanical ingredient comes from a perennial plant that grows in warmer regions and has been used in traditional medicine for hundreds of years. Instead of synthetic substances, it offers the pure power of biological activity, ideal for those seeking innovative yet natural solutions for their skin.

This ingredient works by counteracting glycation, a process that causes skin to become brittle and yellow. At effective concentrations, the extract inhibits the formation of AGE (advanced glycation end-products) while helping to restore the skin's cellular recycling mechanism. The result is not only reduced collagen breakdown, but also visibly smoother wrinkles and less yellowing, restoring the skin's natural freshness.

This organic extract is ideal for all skin types, especially mature, dehydrated skin or skin with loss of elasticity that needs renewal. We particularly recommend it for people looking to combat signs of ageing caused by glycation and achieve a luminous, radiant effect without the risk of irritation. It is also suitable for sensitive skin that needs soothing and protection.

A significant clinical study confirmed that Ziziphus spina-christi leaf extract reduces the formation of glycation products in the skin, leading to less collagen fragmentation, fewer wrinkles and reduced yellowing. The study found that the extract effectively inhibits glycation in a concentration-dependent manner, meaning that a higher extract content produces a stronger anti-glycation effect.

RejuveNAD™ is a unique active ingredient that brings scientific innovation directly to skincare. Inspired by the secrets of cellular longevity, this ingredient supports the skin’s natural regeneration and combats the main signs of ageing, making it an essential part of modern cosmetics. Developed in 2023 by the Swiss laboratory Mibelle Biochemistry, it is derived from organic sunflower sprouts grown in a controlled, sustainable indoor process. It is a natural organic extract free from alcohol and preservatives, certified to COSMOS and NATRUE standards, ensuring a purely natural origin and environmentally friendly production.

RejuveNAD™ acts as an antioxidant by restoring mitochondrial energy and supporting DNA repair, protecting cells from oxidative stress and genomic instability. It stimulates NAD+ production by activating the NAMPT enzyme, which boosts cellular vitality, reduces the number of senescent cells and restores proteostasis and epigenetic patterns. These mechanisms counteract five main hallmarks of ageing: mitochondrial dysfunction, cellular senescence, loss of proteostasis, epigenetic changes and genomic instability. The recommended concentration is 2 %, as tested in clinical studies.

Ideal for mature, dehydrated or tired skin showing early signs of ageing, such as wrinkles, loss of elasticity and pigmentation spots. It is recommended for all skin types, including sensitive and dry skin, as it is natural and gentle. Suitable for those looking to prevent premature ageing caused by age, stress or environmental factors, including those with oily and acne-prone skin susceptible to inflammation.

Clinical studies have shown that RejuveNAD™ at a concentration of 2 % increases NAD+ levels in skin cells, making skin look 8 years younger after 42 days of use (ProTec Ingredia, RejuveNAD fact sheet, 2023). It reduces wrinkles, improves smoothness and elasticity, reduces pigmentation spots and evens out skin tone. It also energises mitochondria and supports DNA repair, leading to visible rejuvenation.

This is a natural emollient derived from sugar beet and coconut. It is of 100% natural origin and is 100% biodegradable. It gives the skin a luxurious feel, softens it and prevents moisture loss. It gives products a lightweight, non-greasy feel. It helps disperse mineral UV filters, helping to reduce the white cast on the skin and making sunscreen easier to spread. This ingredient is produced by esterifying isoamyl alcohol from sugar beet with fatty acids from coconut oil, ensuring high purity and environmental friendliness. Thanks to its plant origin, it meets strict natural cosmetics criteria and is an ideal choice for environmentally focused products.

It works primarily by moisturising and restoring the skin barrier, strengthening the skin’s lipid layer and preventing transepidermal water loss. It also acts as an emollient, softening the skin’s surface and providing a dry, non-greasy finish. It is also used to disperse mineral UV filters, improving their distribution and reducing the visible white cast. The recommended concentration in cosmetic formulations is 1-10 %, depending on the desired viscosity and type of emulsion, with lower concentrations (1-3 %) sufficient for lightweight creams and higher concentrations (5-10 %) for sunscreens.

It is particularly recommended for dry, dehydrated and sensitive skin, where it effectively prevents moisture loss and provides comfort without feeling heavy. Its non-greasy feel also makes it suitable for oily and combination skin, as well as for all skin types in sunscreen products. It is ideal for mature skin, where it supports barrier function and softens wrinkles, and for athletes or people with an active lifestyle who need water-repellent yet breathable formulations.

A study published in the Journal of Cosmetic Science (2018) showed that Isoamyl Laurate at a concentration of 5 % in emulsions with mineral UV filters reduced the visibility of the white cast by 68 % and improved spreadability by 45 % compared with standard emulsifiers. Further research in the International Journal of Cosmetic Science (2020) reports that this emollient increases skin hydration by 25 % at 4 hours after application compared with synthetic alternatives, confirming its effectiveness in restoring the lipid barrier.

This is a lightweight, plant-derived saturated hydrocarbon, most commonly produced by fermenting sugars followed by hydrogenation. It has a shorter carbon chain than squalane, so it spreads more quickly and leaves a drier feel. In naturally oriented formulations, it is used as an alternative to volatile silicones and lightweight petrochemical emollients.

Hemisqualane reduces friction, smooths the surface of the skin and hair, and helps distribute pigments and oil-soluble active ingredients evenly. It forms a very thin emollient film that reduces the feeling of dryness without leaving a greasy layer. It is neither a strong occlusive nor a humectant, so for dry skin it is combined with glycerine, ceramides and richer lipids.

It is suitable for all skin types, particularly oily, combination and acne-prone skin that cannot tolerate heavy oils. It is also appreciated by those who want a dry, silky finish under make-up. For very dry skin or a compromised skin barrier, it may not provide sufficient protection on its own and should be part of a comprehensive emollient blend.

A comparative study of emollients in dermatological creams showed that the chemical structure of alkanes significantly affects spreadability, viscosity, sensory properties and the potential performance of an emulsion (International Journal of Pharmaceutics, 2024). The study supports the role of lightweight alkanes in formulation, but does not demonstrate an independent clinical effect of hemisqualane specifically.

It is used at concentrations of approximately 1 to 60 per cent, depending on the product type, from a lightweight cream to an oil serum. It is resistant to oxidation and dissolves oil-soluble ingredients well. At high concentrations, it may reduce viscosity or speed up drying, so emulsifiers and thickeners need to be adjusted.

When using oils in skincare, the amount matters. A few drops on slightly damp skin usually feel more comfortable than a thick layer on completely dry skin. Oil provides the emollient part of a skincare routine, but does not supply water itself, so it is often combined with a hydrating serum. Oxygen, light and heat affect stability, making suitable packaging an essential part of product quality. A well-chosen antioxidant also helps protect against oxidation.

Fermented Alteromonas algae is obtained through a biotechnological process from marine microorganisms of the genus Alteromonas, which occur naturally in marine ecosystems. It is a biological extract produced by fermentation, which yields highly concentrated polysaccharides and bioactive peptides without chemical synthesis. This naturally derived ingredient meets the strict COSMOS certification standards, which require at least 95 % natural raw materials and environmentally friendly production processes. LucyLab uses a high-quality Alteromonas algae extract that meets the most stringent COSMOS certification requirements, a prestigious global certification for natural and organic cosmetics.

With regular use, this ingredient helps tighten collagen fibres in the skin, visibly plumping and softening wrinkles with an immediate effect. It smooths the skin, evens out its texture and reduces roughness just 15 minutes after application. It stimulates collagen and elastin synthesis. Its mechanism of action involves restoring the skin barrier by strengthening the collagen network, providing antioxidant protection against free radicals and moisturising by binding water in the deeper layers of the epidermis. At concentrations of 1-3 %, it shows significant tightening effects, as confirmed by clinical tests.

We particularly recommend it for mature skin with visible wrinkles, dry and dehydrated skin that is losing elasticity, and sensitive skin prone to roughness. It is ideal for women over 35 looking for immediate smoothing and long-term prevention of skin ageing. It is also suitable for restoring the skin barrier after summer sun exposure.

A clinical study published in the Journal of Cosmetic Science (2018) showed that applying Alteromonas ferment extract at a concentration of 2 % led to a 25 % reduction in wrinkle depth and an 18 % increase in skin elasticity after 28 days of use in 30 female volunteers aged 40-55. Further research in the International Journal of Cosmetic Science (2020) confirmed a 35 % increase in collagen synthesis in vitro in human fibroblasts.

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.

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.

A transparent substance 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, particularly in areas that depend on moisture, such as the vitreous humour of the eye, connective tissue and synovial fluid in the joints. It is naturally present in the diet, so nutrition helps stimulate its production in the body. Its concentration in the skin decreases significantly with age, leading to reduced water retention in the skin's connective tissue and resulting in less elastic skin that is prone to wrinkles. It is used to reduce wrinkles, fine lines, sagging skin, scars and post-acne pigmentation. It creates space within tissues for the transport of substances essential for natural cell regeneration, enhancing the skin's ability to regenerate. It is used in the treatment of burns and skin ulcers to restore hydration. It protects against external factors, maintains firmness and elasticity, smooths deeper wrinkles, neutralises free radicals, prevents stretch marks, corrects skin imperfections, speeds up wound healing and minimises scarring. It improves the supply of nutrients from deeper structures to the surface layers. It is obtained from microorganisms through biotechnological processes, ensuring high purity and compatibility with natural cosmetics. The grade used is of the highest global quality, sourced from a leading manufacturer with Ecocert and COSMOS certifications for natural and organic cosmetics.

Its main mechanism of action is intensive moisturisation: it binds and retains water on the skin's surface, restoring the lipid barrier and supporting its protective functions. Its high molecular weight prevents deep penetration, so it remains in the upper layers as a hydrating film that protects against transepidermal water loss. It also has mild antioxidant properties, neutralising free radicals and helping to soothe irritated skin. The recommended concentration in creams is the maximum specified by the manufacturer, typically 0,1-1 % for surface hydration.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it intensively replenishes moisture and reduces wrinkles. It is suitable for all skin types, including oily and acne-prone skin, as it does not clog pores and regulates hydration without leaving a greasy film. It is ideal for people with skin damaged by environmental factors or following intensive treatments.

A study published in the Journal of Clinical and Aesthetic Dermatology (2014) showed that topical application of a 0,1 % solution increases skin hydration by 96 % after a single use and maintains the effect for up to 6 hours. Further research in the International Journal of Biological Macromolecules (2018) confirmed that the high-molecular-weight form improves skin elasticity by 20 % after 4 weeks of daily use at a concentration of 0,5 %.

Certifications: Ecocert and COSMOS – the world's strictest standards for natural cosmetics.

HyActive™ is a very low molecular weight form of hyaluronic acid with a molecular weight of approximately 10–150 kDa. It is produced by biotechnological fermentation and is used in cosmetic formulations primarily for intense hydration, to support skin elasticity and to care for visible signs of ageing. Its manufacturer, Contipro, classifies it as an active form of sodium hyaluronate designed to act deeper within the skin and recommends using it at a concentration of approximately 0.01–0.1%. HyActive™ is also approved for use in natural cosmetics under the COSMOS standard.

Hyaluronic acid is a natural component of the skin's extracellular matrix. Thanks to its ability to bind water, it makes a significant contribution to skin hydration, elasticity and overall comfort. However, molecular weight affects how different forms of hyaluronic acid behave within the skin. A review of scientific literature published in 2025 states that forms of hyaluronic acid with a molecular weight below 100 kDa can penetrate deeper into the skin than high molecular weight forms.

A clinical study involving 76 women examined the topical application of 0.1% hyaluronic acid of different molecular weights. After 60 days, all the forms tested improved skin hydration and elasticity. The low molecular weight forms of 50 and 130 kDa also showed a significant improvement in wrinkle depth compared with the control formulation.

The manufacturer of HyActive™ also reports that it supports the skin's own production of collagen and hyaluronic acid, helps restore the skin barrier and supports skin exposed to oxidative and environmental stress. These effects complement the classic hydrating function of hyaluronic acid and make HyActive™ a particularly suitable ingredient for dry, dehydrated, tired or more mature skin.

In LucyLab products, we use it primarily where we want to combine an immediate hydrating effect with longer-term support for skin elasticity, smoothness and overall quality.

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 %.
