Abstract
Abstract The cosmetic compositions contain an active substance which promotes the collagenase activity in the skin in order to counteract the decrease in collagenase activity in the skin during the course of skin ageing but also on excessive exposure to light and sun. The active substance consists of a protein fraction obtained from blood serum or of polysaccharide sulphates such as heparin or dextran sulphate. The cosmetic compositions can also contain natural soluble collagen (tropocollagen) as further active substance.
