Patent FR-2761884-A1 (FR)
Inventor: GREFF DANIEL
IPC: A61Q19/00
Filed: 1997-04-10
Abstract: The invention relates to the use of the extracts of plants of the genus Lapsana and of the species Lapsana communis L (Asteraceae) in particular. Said extracts are preferably obtained by maceration in a hydroglycolic mixture, and are used in cosmetic or dermopharmaceutical preparations for their skin-protective and radical-resistant properties. The actions of such preparations produce anti-ageing and anti-wrinkle effects, and protect the basic constituents of the cutaneous structure from the harsh effects of oxygen free radicals while prolonging the skin's suppleness and protective function. Said compositions supply protective cellular action against the deleterious effects of free radicals and those of enzymes such as elastase and hyaluronidase.
