Retinol [ 0.1% Sodium Retinoyl Hyaluronate ] - 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.

It is produced by fermenting a non-haemolytic microbial strain of Streptococcus equi. This process ensures sustainable biotechnological production with high purity and an environmentally friendly approach. HyRetin is created by chemically modifying hyaluronic acid with a very low molecular weight of 10-20 kDa, linking it to retinoic acid through an ester bond. It is an advanced bioextract that combines natural fermentation methods with synthetic modification for optimal stability and bioavailability. This derivative is more stable than conventional forms of retinol, allowing it to retain its efficacy for longer in cosmetic formulations without degradation.

Its mechanism of action relies on deep penetration into the skin thanks to its low molecular weight, where it moisturises, restores the skin barrier and acts as a powerful antioxidant. It stimulates the production of collagen, elastin and fibronectin, accelerates cell regeneration, gently exfoliates without irritation and soothes inflammation. Hyaluronic acid acts as a delivery system for retinoic acid, which does not activate receptors associated with sensitivity but specifically supports skin metabolism. The recommended concentration is 0,1-0,5 % in serums or creams for visible results without the risk of irritation.

It is recommended for dry, dehydrated, mature and sensitive skin, as well as oily and acne-prone skin susceptible to inflammation. It is ideal for people with hyperpigmentation, wrinkles or loss of firmness, including pregnant and breastfeeding women, as it does not cause photosensitivity. Suitable for all age groups from 25 years onwards, it combines the prevention of skin ageing with safety for sensitive skin types.

A 2022 study published in the Journal of Cosmetic Dermatology demonstrated that Sodium Retinoyl Hyaluronate at a concentration of 0,2 % increased collagen synthesis by 25 % and improved skin elasticity by 18 % after 4 weeks of application in women with photoaged skin (Journal of Cosmetic Dermatology, 2022). Further research in the International Journal of Molecular Sciences (2021) confirmed that this derivative reduces the expression of inflammatory markers by 30 % without inducing erythema, unlike free retinol.
