Definitions
- the invention relates to a skin depigmenting composition
- a skin depigmenting composition comprising, in a physiologically acceptable medium, mequinol (or 4-hydroxyanisole), and at least one unsaturated or polyunsaturated fatty acid and its pharmaceutical or cosmetic use.
- the composition according to the invention may also contain a sunscreen.
- the pigmentation of the skin results from the synthesis of melanin in the melanocytes of the dermis by the transformation of tyrosine under the influence of a cuproprotein enzyme tyrosinase.
- Mequinol is a compound whose depigmenting activity is known. Indeed it acts as a substrate for tyrosinase and therefore blocks the mechanism of melanin synthesis in the dermis (Riley P, Journal of Pathology (1969), 97 (2), 185-191) Indeed, disorders Pigments such as hyperpigmentation are the result of excessive production of melanin. By blocking or decreasing this synthesis, one can obtain a depigmentation effect
- the Applicant has surprisingly discovered that the combination of mequinol and a fatty acid makes it possible to obtain, by synergistic effect, a depigmenting response much more effective than that obtained with mequinol alone and above all to provide better comfort of use.
- the invention relates to a depigmenting composition for the skin comprising, in a physiologically acceptable medium, mequinol and an unsaturated fatty acid.
- physiologically acceptable medium means a medium compatible with the skin, the mucous membranes and / or the integuments.
- fatty acid is meant a constituent of lipids.
- the fatty acids differ from each other by their chain length and their degree of saturation, namely the number of carbon constituting the chain and the nature of the bonds, single or double, connecting the carbon atoms to each other.
- saturated fatty acid according to the invention means the unsaturated fatty acids and the polyunsaturated fatty acids.
- unsaturated fatty acid By way of nonlimiting example of unsaturated fatty acid according to the invention, mention may be made of linoleic acid, arachidonic acid, sorbic acid, docosahexaenoic acid, or eicosapentaenoic acid.
- composition containing the combination according to the invention makes it possible to obtain a clear whitening of the skin.
- the invention also relates to a depigmenting composition for the skin comprising, in a physiologically acceptable medium, mequinol, at least one unsaturated or polyunsaturated fatty acid and at least one sunscreen.
- the composition according to the invention advantageously comprises between 0.0001 and 20% by weight of mequinol relative to the total weight of the composition and between 0.0001 and 20% by weight of fatty acid relative to the total weight of the composition, and preferably, respectively, between 0.001 and 10% by weight of mequinol relative to the total weight of the composition and between 0.025 and 10% by weight of fatty acid relative to the total weight of the composition.
- the composition can also comprise at least one sunscreen in preferential concentrations ranging from 0.001 to 30.00% by weight relative to the total weight of the composition.
- the composition may include several sun filters.
- each sunscreen can be added at a concentration ranging from 0.001 to 20% by weight relative to the total weight of the composition.
- compositions according to the invention can also comprise any additive usually used in the cosmetic or pharmaceutical field, such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfumes, essential oils, cosmetic active ingredients, moisturizers, vitamins, essential fatty acids, sphingolipids, self-tanning compounds, soothing and protective agents for the skin.
- any additive usually used in the cosmetic or pharmaceutical field such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfumes, essential oils, cosmetic active ingredients, moisturizers, vitamins, essential fatty acids, sphingolipids, self-tanning compounds, soothing and protective agents for the skin.
- any additive usually used in the cosmetic or pharmaceutical field such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfume
- the present invention also relates to a pharmaceutical composition as described above as a medicament.
- the present invention also relates to a cosmetic composition.
- compositions containing the combination according to the invention can have all the galenical forms normally used for a topical application, for example under form of solutions, gels, dispersions of the lotion or serum type, of emulsions of liquid or semi-liquid consistency of the milk type, obtained by dispersion of a fatty phase in an aqueous phase (O / W) or vice versa (E / H), or suspensions or emulsions of soft, semi-solid or solid consistency of the cream or gel type, or alternatively of microemulsions, microcapsules, microparticles or vesicular dispersions of the ionic and / or nonionic type.
- These compositions are prepared according to the usual methods.
- the cosmetic or dermatological compositions of the invention may contain adjuvants customary in the cosmetic or dermatological field, such as emulsifiers, hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents other than titanium oxide and ⁇ -hydroxy acid, preservatives, antioxidants, perfumes, fillers, filters and coloring matters.
- adjuvants customary in the cosmetic or dermatological field, such as emulsifiers, hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents other than titanium oxide and ⁇ -hydroxy acid, preservatives, antioxidants, perfumes, fillers, filters and coloring matters.
- the amounts of these various adjuvants are those conventionally used in the cosmetic and / or dermatological fields, and for example from 0.01% to 20% of the total weight of the composition.
- These adjuvants depending on their nature, can be introduced into the fatty phase, into the aqueous phase and / or into the lipid vesicles.
- the invention also relates to the use of the composition according to the invention as described above in the pharmaceutical and cosmetic field.
- compositions of the invention are particularly suitable for the treatment and prevention of pigmentation disorders.
- the compositions of the invention are suitable for the treatment and prevention of hyperpigmentary disorders such as melasma, chloasma, lentigines, senile lentigo, vitiligo, freckles, post-inflammatory hyperpigmentations due to abrasion. , a burn, a scar, a dermatosis, a contact allergy; nevi, hyperpigmentations with genetic determinism, hyperpigmentations of metabolic or drug origin, melanomas or any other pigmentary lesions, in particular those induced by photo-induced or chronological aging of the skin and integuments.
- compositions according to the invention are suitable for the treatment of melasma.
- the compositions according to the invention also find an application in the cosmetic field, in particular in the protection against the harmful aspects of the sun, in particular, against pigmentary spots.
- the invention also relates to a non-therapeutic cosmetic treatment process for beautifying the skin and / or improving its surface appearance, characterized in that a composition is applied to the skin and / or its integuments comprising mequinol and an unsaturated or polyunsaturated fatty acid.
