Definitions
- Cosmetic composition comprising an extract of Adenium obesum, its use and a method of cosmetic care comprising the application
- the present invention relates to a cosmetic composition
- a cosmetic composition comprising an extract of Adenium obesum, a new use of an extract of this plant in the field of cosmetics, its use in particular to reinforce the cutaneous barrier and / or the dermo-epidermal junction, and a method of cosmetic care comprising the application.
- the skin is the outermost layer that protects our body.
- stratum corneum and the epidermis which form the most superficial layers of the skin must have a resistance to the forces and mechanical stresses exerted on them, and also a resistance to the evaporation of water.
- the intercellular junctions of the epithelial cells for example of the epidermis, can be classified into two groups according to their ultrastructure and their function:
- the adhering or anchoring junctions also called “desmosomes”, which allow the mechanical attachment of the cells to one another and reinforce the mechanical strength of the sealing systems,
- Watertight junctions also called “tight junctions” capable of limiting the permeability of the stratified epithelium that is the epidermis and which seal against water between two cell compartments.
- Desmosomes are binding sites for keratins between two cells (keratinocytes or corneocytes) and thus strengthen the adhesion of keratinocytes to each other, from keratinocytes to corneocytes of the stratum and corneocytes to each other. These adherent or anchoring junctions allow groups of cells to act as solid structural units by associating the cytoskeletal elements of one cell with those of another.
- the keratin filaments within the keratinocytes and corneocytes form a structural framework for their cytoplasm and provide resistance to the lateral and vertical forces and mechanical stresses that these cells undergo.
- Desmosomes are complex structures that contain two main proteins, desmoglein, a glycoprotein with a molecular weight of 160 kDa, and desmoplakin with a molecular weight of 285 kDa that bind the keratin filaments.
- Desmosomes therefore play a key role in these mechanisms of resistance to the stresses to which the cells of the epidermis are subjected and in the prevention of the evaporation of intercellular water, a phenomenon responsible for cutaneous dryness and accelerating during aging. skin.
- JP 2001288113 discloses a cosmetic composition comprising a substance allowing the expression of desmoglein, desmocollin or desmoplakin, constitutive proteins of desmosomes with a view to obtaining a preventive effect or improving effects of aging of the skin, such as skin dryness or the formation of wrinkles.
- FR 2 803 523 relates to a cosmetic composition based on extracts of seaweed from the family Dictyotales, more particularly an extract of Padina pavonica causing the maturation of keratinocytes, with amplification of the synthesis of cytokeratins 1 and 10, and increase of desmosomal proteins.
- Adenium obesum also known as desert rosé, is a plant belonging to the Apocynaceae family, native to Yemen and cultivated as a tropical ornamental plant.
- WO 96/11015 discloses a homeopathic moisturizing composition for oral absorption. Indeed, the moisturizing effect aims to increase or facilitate the passage of water and ions in the intestine. This document does not disclose or teach any cosmetic application or any effect on the skin. There is no mention of any excipient.
- an extract of Adenium obesum stimulates the expression of proteins of the desmosomes present at the level of the intercellular junctions of the cells forming the epidermis and the stratum corneum, and more particularly makes it possible to stimulate the expression of the desmoglein, and in particular desmoglein 1, or desmoplakin, which are two of the constitutive proteins of the desmosomal junctions of the epidermis, involved in inter-keratinocyte or inter-corneocyte cohesion.
- Such stimulation makes it possible to increase the efficiency of these adherent junctions and thus to improve the resistance to stresses experienced by these cell layers and to limit the evaporation of the intercellular water.
- the reinforcement of the cutaneous barrier results mainly from these two physiological phenomena which are, on the one hand, an improved resistance to the stresses suffered by the cells of the stratum corneum and the epidermis and, on the other hand, a greater resistance to evaporation of the intercellular water.
- Such stimulation thus makes it possible to reinforce the cohesion between the cell compartments, in particular between the stratum corneum and the living epidermis, or between the epidermis and the dermis, that is to say the strengthening of the junction. dermo-epidermal.
