Definitions
- the present invention relates to the use, as active principle in a cosmetic composition or for the preparation of a pharmaceutical composition, of an effective amount of at least one 2-amino-alkane-1, 3-diol, or of one of its derivatives, intended for treating the signs of skin aging as well as a non-therapeutic method for treating skin aging.
- Skin aging resulting from effects on the skin of intrinsic or extrinsic factors, is manifested by the appearance of fine lines and wrinkles, by the yellowing of the skin which develops a parchment appearance accompanied by the appearance of pigment spots, by the disorganization of the elastin and collagen fibers leading to a loss of elasticity, flexibility and firmness and by the appearance of telangiectasias.
- Some of these signs of aging are more particularly linked to intrinsic or physiological aging, that is to say to “normal” aging linked to age, while others are more specific to extrinsic aging, ie that is to say aging generally caused by the environment; this is more particularly photo-aging due to exposure to the sun, light or any other radiation.
- the invention is concerned with intrinsic or physiological aging as well as extrinsic aging.
- the skin changes resulting from intrinsic or physiological aging are the consequence of genetically programmed senescence in which endogenous factors intervene. This intrinsic aging notably causes a slowing down of the renewal of skin cells. Histologically the skin is generally thinned, both epidermally and dermally. The density of the fibrous macromolecules of the dermis (elastin and collagen) is reduced.
- extrinsic aging leads to clinical alterations such as thick wrinkles and the formation of soft and / or tanned skin, and histopathological changes such as an excessive accumulation of elastic material in the upper dermis and degeneration of the fibers. collagen.
- US Pat. No. 4,603,146 describes the use of retinoic acid and its derivatives in cosmetic compositions, with a view to combating skin aging.
- numerous patents and publications see for example application EP-A-413 528) as well as many commercial cosmetic compositions teach the use of ⁇ -hydroxy acids such as lactic acid, glycolic acid or else citric acid to treat skin aging.
