Definitions
- the invention relates to the use of DHEA and / or its precursors and chemical and / or biological derivatives, in a cosmetic composition or for the manufacture of a dermatological composition for topical application to the skin, with a view to preventing or treat the atrophy of the epidermis.
- Human skin is made up of two compartments, namely a deep compartment, the dermis, and a superficial compartment, the epidermis.
- the dermis provides the epidermis with solid support. It is also its nourishing element. It mainly consists of fibroblasts and an extracellular matrix itself composed mainly of collagen, elastin and a substance, known as the fundamental substance, components synthesized by the fibroblast. There are also leukocytes, mast cells or tissue macrophages. It also contains blood vessels and nerve fibers.
- the epidermis is in contact with the external environment. Its role is to protect the body from dehydration and external aggressions, whether chemical, mechanical, physical or infectious.
- the natural human epidermis is mainly composed of three types of cells which are the keratinocytes, very majority, the melanocytes and the Langerhans cells. Each of these cell types contributes by its own functions to the essential role played in the body by the skin.
- Epidermal lipids are synthesized mainly in the living epidermis. They are essentially made up of phospholipids, sphingolipids, cholesterol, free fatty acids, triglycerides, cholesterol esters and alkanes. During cell differentiation, the phospholipids, the role of which is to develop the fluid structure of the cell membranes of the living layers of the epidermis, are gradually replaced by a mixture composed of most fatty acids, cholesterol and sphingolipids, essential constituents of the stratum corneum of the epidermis (stratum corneum).
- the lipids of the inter-comocytic cement of the skin are organized in lamellar bi-layers or sheets and participate in the cohesion of the stratum corneum in order to maintain the integrity of the barrier and its protective role, anti-penetration, anti-irritation etc.
- an activation of the metabolism in the living cells of the epidermis, or an increase in cell proliferation in the living layers, will result in an increase in the content of the epidermis in phospholipids (sphingomyelin / phosphatidylinositol or phospholipids membranes, respectively) and will result in an increase in the size or number of living cells, i.e. thickening of the epidermis.
- phospholipids sphingomyelin / phosphatidylinositol or phospholipids membranes, respectively
- DHEA DHEA to remedy dermal atrophy by inhibiting the loss of collagen and connective tissue
- US Pat. No. 5,843,932 It has also been described in US Pat. No. 5,736,537 the oral use of DHEA esters, in particular DHEA salicylate, for regulating the atrophy of the skin due to thinning or general degradation of the dermis.
- DHEA dehydroepiandrosterone
- Exogenous DHEA is also known for its ability to promote keratinization of the epidermis (JP-07 196 467) and to treat dry skin by increasing the endogenous production and the secretion of sebum and thereby strengthening the barrier effect of the skin (US Pat. No. 4,496,556).
- DHEA applied topically could have any effect on the atrophy of the epidermis.
- the anti-atrophic effect of DHEA on the dermis did not suggest that this compound could have an effect on the epidermis, the cells involved and the mechanisms of action being very distinct in these two compartments of the skin. .
- the present invention therefore relates to the use of DHEA and / or its precursors and chemical and / or biological derivatives, in a cosmetic composition for topical application to the skin, as an agent for preventing or treating atrophy of the epidermis.
- the invention also relates to the use of DHEA and / or its precursors and chemical and / or biological derivatives, for the manufacture of a composition for topical application to the skin, intended to prevent or treat atrophy of the epidermis.
- the invention relates to the use of DHEA and / or its precursors and chemical and / or biological derivatives, in a cosmetic composition for topical application to the skin, as an agent for preventing or treating the signs of skin aging linked to the skin. atrophy of the epidermis.
- DHEA has the following formula (I):
- DHEA precursors is meant its immediate biological precursors or substrates, as well as its chemical precursors.
- biological precursors are ⁇ 5-pregnenolone, 17-hydroxy pregnenolone and 17 ⁇ -hydroxy pregnenolone sulfate, without this list being limiting.
- chemical precursors are sapogenins such as diosgenin (or spirost-5-en-3-beta-ol), hecogenin, hecogenin acetate, smilagenin and sarsapogenin, as well as natural extracts thereof. containing, in particular fenugreek and Dioscorea extracts such as wild yam root or Wild Yam, without this list being exhaustive.
- DHEA derivatives are understood to mean both its biological derivatives and its chemical derivatives.
- biological derivatives there may be mentioned in particular ⁇ 5-androstene-3,17-diol and ⁇ 4-androstene-3,17-dione, without this list being limiting.
- chemical derivatives mention may in particular be made of the salts, in particular the water-soluble salts, such as DHEA sulfate.
- esters such as the esters of hydroxycarboxylic acids and of DHEA described in US Pat. No. 5,736,537 or the other esters such as salicylate, acetate, valerate and enanthate of DHEA.
- composition containing DHEA and / or at least one of its precursors or derivatives is suitable for topical use and therefore it contains a physiologically acceptable medium, that is to say compatible with the skin.
- This composition may contain from 10 's to 10% by weight, preferably from 0.1 to 5% by weight, and more preferably about 1% by weight of DHEA and / or its precursor or derivative, based on the total weight of the composition.

- aqueous solution possibly gelled
- a dispersion of the lotion type possibly biphasic of an emulsion obtained by dispersion of a fatty phase in, an aqueous phase (O / W) or vice versa (W / O), or of a triple emulsion (W / O / W or O / W / O) or of a vesicular dispersion of
- This composition can be more or less fluid and have the appearance of a white or colored cream, an ointment, a milk, a lotion, a serum, a paste, a foam. . It can optionally be applied to the skin in the form of an aerosol. It can also be in solid form, in particular in the form of a stick. It can be used as a care product and / or as a make-up product for the skin.
- the composition of the invention can also contain the adjuvants usual in the cosmetic field, such as hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents, preservatives, antioxidants, solvents, perfumes, fillers, filters, pigments, odor absorbers and coloring matters.
- the amounts of these various adjuvants are those conventionally used in the field under consideration, 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, into the lipid vesicles and or into the nanoparticles. In any event, these adjuvants, as well as their proportions, will be chosen so as not to harm the desired properties of the combination of active agents according to the invention.
