Abstract
The present invention relates in general terms to the use of saponins or sapogenols, particularly those extracted from a plant, preferably from soya or Medicago, in cosmetology and for the manufacture of pharmaceutical compositions for treating the skin in order to increase the amount of collagen IV in the dermo-epidermal junction. It further relates to novel cosmetic or pharmaceutical compositions which promote an increase in the amount of collagen IV in the dermo-epidermal junction, and to a method of cosmetic treatment using a saponin or a sapogenol. The invention is applicable in cosmetics, preferably in an anti-wrinkle treatment, and in pharmacy in the treatment of diseases associated with a deficiency of the dermo-epidermal junction resulting from an insufficient amount of collagen IV.
