Anallerg® -- HPR
INCI:Hydroxypinacolone Retinoate
HPR is a cosmetic grade ester of retinoic acid. Its unique feature is that it has inherent retinoic acid activity and directly binds to retinoic acid receptor without metabolic decomposition into a more biologically active form. Compared with retinol, it has been proved to be more stable and less irritating to the skin. HPR is an effective substitute for some vitamin A with weak efficacy and retinoic acid , and has no harmful side effects.
