Abstract;In the course of our studies on the further application of licorice as a cosmetic ingredient, we studied a new dermatological availability in the licorice extract containing licochalcone-A as a main principle, Polyol Soluble Licorice Extract P-U, prepared from the roots of Glycyrrhiza inflata Batalin. As a result, this extract showed several activities such as inhibitory actions of testosterone 5.ALPHA.-reductase, lipase and phospholipase A2, as well as androgen receptor antagonist, antimicrobial and SOD-like actions, which relate to skin care, especially the suppression of acne formation and development. On basis of this evidence, a trial of Polyol Soluble Licorice Extract P-U with acne patients was carried out and the efficacy was demonstrated clinically. (author abst.)
