Hyaluronic Acid [ Relift + Renew HA Complex ] - Booster

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).

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.

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.

This sodium salt of hyaluronic acid is produced through biotechnological fermentation and then processed to achieve a low molecular weight. The smaller chains spread more easily within the surface layers of the skin and form a less noticeable sticky film. The ingredient is water-soluble and is used in concentrated hydrating and smoothing serums.

Supreme HyalRelift binds water, supports the suppleness of the stratum corneum and may visibly soften fine lines caused by dehydration. The low-molecular-weight form penetrates the epidermis better than very large chains, but it is not an injectable filler and does not create lasting volume. At high concentrations, it can feel sticky or increase tightness in dry climates, so it is combined with emollients and an occlusive layer.

We recommend it for dehydrated, dry, mature and oily skin. It is suitable for use under a light moisturiser and in after-sun products. For very sensitive or inflamed skin, a carefully formulated low dose should be used, as very small hyaluronate fragments may stimulate inflammatory signals under certain conditions.

A clinical study using 0,1 per cent formulations of hyaluronic acid of different molecular weights showed significant improvements in hydration and elasticity with all variants. After 60 days, the 50 and 130 kDa forms significantly reduced wrinkle depth compared with placebo (Journal of Drugs in Dermatology, 2011). This finding supports the importance of low molecular weight for smoothing the skin.

The active concentration is usually around 0,05 to 0,2 per cent, depending on molecular weight and purity. The powder must be hydrated slowly in water without forming lumps. When combining several types of hyaluronate, stickiness, viscosity and microbiological stability need to be monitored.

In your daily routine, it is worth assessing longer-term comfort, suppleness and whether your skin feels less tight during the day. In dry climates, a humectant also needs an emollient or occlusive ingredient to lock in the water it retains. The result therefore depends on the whole formula, consistent use and gentle cleansing, rather than on a single high concentration. Regular application in appropriate amounts is also important.

This sodium salt of hyaluronic acid, produced by fermentation, has a higher molecular weight and long polysaccharide chains. It remains mainly on the skin’s surface, where it forms a flexible, hydrating film. In cosmetics, it is used to provide immediate comfort, reduce tightness and support a smooth appearance without an oily feel.

Supreme HyalRenew attracts water and forms a thin network on the skin’s surface, slowing water evaporation. Its higher molecular weight provides a film-forming and soothing effect, but it does not penetrate deep into the dermis or act as a filler. It works well alongside low-molecular-weight hyaluronic acid, glycerine and lipids, as different types of hydration work in different layers.

It is suitable for dry, dehydrated, sensitive and mature skin, as well as oily skin that needs non-greasy hydration. It is particularly useful for people whose skin feels tight after cleansing or in air-conditioned environments. In very dry air, it is advisable to follow the serum with a cream to help keep water in the skin.

A clinical study of 0,1 per cent creams containing hyaluronic acid of different molecular weights showed a significant increase in hydration and elasticity with regular use (Journal of Drugs in Dermatology, 2011). Higher molecular weights worked mainly on the surface, while smaller forms had a more pronounced effect on wrinkle depth.

The usual concentration is approximately 0,05 to 0,3 per cent. The powder should be hydrated slowly and protected from intense shear once a gel has formed, as this can mechanically shorten the chains. Excessive amounts cause stickiness and pilling when layering products.

In your daily routine, it makes sense to focus on longer-term comfort, suppleness and whether your skin feels less tight throughout the day. In a dry climate, a humectant also needs an emollient or occlusive ingredient to lock in the water it retains. The result therefore depends on the overall formula, consistent use and gentle cleansing, rather than a high concentration of a single ingredient. Regular application in appropriate amounts is also important.

The hydrolysed form of hyaluronic acid with a very low molecular weight of 5 kDa is obtained through modern microbial fermentation using non-pathogenic bacteria such as Streptococcus sp. or Escherichia coli, ensuring high purity and safety without animal-derived materials. This biologically extracted ingredient naturally resembles the hyaluronan found in the human body, where it forms part of the synovial fluid and extracellular matrix. Hyaluronic acid was first isolated in 1934 from the fluid inside a cow's eye, but biotechnological production is now preferred as it offers a range of molecular weights and better compatibility with the skin.

The hydrolysed form of hyaluronic acid with a very low molecular weight of 5 kDA provides long-lasting skin hydration, restores the skin barrier and stimulates the skin's own production of hyaluronic acid. It acts as an antioxidant to protect the extracellular matrix, soothes irritation, reduces inflammatory processes and supports the formation of new blood vessels to improve tissue nourishment. Thanks to its low molecular weight, it penetrates deep into the skin, improves elasticity and reduces wrinkles. IN VIVO studies have shown: a 51% reduction in wrinkles, a 31% reduction in inflammatory processes in the skin and reduced redness, and a 29% increase in the skin's own production of hyaluronic acid. Further benefits: improved skin elasticity and reduced wrinkles, support for the formation of new blood vessels to nourish the skin, stimulation of the skin's own hyaluronic acid production, soothing effects, long-lasting hydration and an improved skin barrier, protection of the extracellular matrix, and relief for irritated skin.

This ingredient is ideal for dry, dehydrated, sensitive, mature and acne-prone skin, supporting hydration without weighing it down. It is recommended for people with wrinkles, loss of elasticity or irritation, including those with oily skin prone to dehydration. Suitable for all age groups concerned with ageing or environmental damage.

An IN VIVO study on OligoHyaferre demonstrated a 51% reduction in wrinkles, a 31% reduction in inflammatory processes and redness, and a 29% increase in the skin's own production of hyaluronic acid (Dulcia Natural, clinical tests). Another study confirms that low-molecular-weight hydrolysed sodium hyaluronate stimulates fibroblasts to synthesise endogenous HA and proteoglycans, improving the skin's viscoelastic properties (Journal of Cosmetic Dermatology, viscosupplementation effects).
