Definitions
- the present invention relates to the field of cosmetic products, more particularly intended for the care of keratinous substances, in particular for the care of the skin of the face and / or the body.
- the invention relates to C-glycoside compounds with an acid, ester or amide group, a cosmetic composition comprising them, a method of preparation, the use of said C-glycosides for the treatment of keratinous substances and in particular the skin; and a method for treating keratin materials using said C-glycosides. More particularly, the present invention aims to propose the use of a new active ingredient for effectively depigmenting and / or lightening, or even bleaching, keratin materials, in particular the skin of the face and / or the body and / or improving the complexion, in particular its homogeneity and its brilliance.
- the color of human keratin materials, especially human skin is mainly determined by the nature and concentration of a pigment, melanin.
- the mechanism of melanogenesis that is, the mechanism of melanin formation, is particularly complex and schematically involves the following main steps:
- tyrosinase is the essential enzyme that regulates the first stages of the synthesis of pheomelanin and eumelanin which are the two types of melanin.
- the pigmentation of the skin of the face and / or the body, and more particularly the pigmentation of the skin, is a function of various factors such as environmental factors related to the seasons of the year, and the origin of the individual.
- a molecule is recognized as depigmenting if, in particular, it interferes with one of the steps of melanin biosynthesis either by inhibiting one of the enzymes involved in melanogenesis or by interposing itself as a structural analogue of one of the chemical compounds. of the synthesis chain of melanin, a chain which can then be blocked and thus ensure depigmentation.
- the main known depigmenting substances are hydroquinone and its derivatives, in particular its ethers such as monomethyl ether and hydroquinone monoethyl ether, kojic acid, arbutin, etc.
- the depigmenting substances may exhibit in particular a certain instability, a low efficiency at low concentration, a biological activity affecting other functions, etc.
- the applicant company has surprisingly and unexpectedly discovered that certain C-glycoside compounds with a particular acid group, ester or amide have a good depigmenting activity for keratinous substances as well as an action which makes it possible to prevent, reduce and / or or to treat an alteration of the complexion of the skin or the shade of the semi-mucous membranes, that is to say in particular an activity making it possible to improve the homogeneity of the complexion and to revive the radiance of the complexion, even at low concentration .
- the skin consists of two compartments, one superficial, the epidermis, and the other deeper, the dermis, which interact.
- the natural human epidermis is composed mainly of three types of cells, which are the keratinocytes, the majority, the melanocytes, and the Langerhans cells. Each of these cell types contributes, through its own functions, to the essential role played in the body by the skin, in particular the protective role of the body against external aggressions called "barrier function".
- the epidermis is conventionally divided into a basal layer of keratinocytes constituting the germinal layer of the epidermis, a so-called spinous layer consisting of several layers of polyhedral cells arranged on the germinal layers, one to three so-called granular layers consisting of flattened cells. containing distinct cytoplasmic inclusions, the keratohyalin grains, and finally the stratum corneum, consisting of a set of layers of keratinocytes at the stage terminal of their differentiation and called corneocytes.
- Corneocytes are anucleate cells consisting mainly of a fibrous material containing cytokeatins, surrounded by a horny envelope.
- the dermis provides the epidermis with a solid support. It is also its nurturing element. It consists mainly of fibroblasts and an extracellular matrix mainly composed of collagen, elastin and a substance called the fundamental substance. These components are synthesized by fibroblasts. There are also leucocytes, mast cells or tissue macrophages. Finally, the dermis is trapped by blood vessels and nerve fibers. The cohesion between the epidermis and the dermis is ensured by the dermal-epidermal junction.
- proteoglycans also called PGs
- glycosaminoglycans also called GAGs
- PGs proteoglycans
- GAGs glycosaminoglycans
