How It Works

The serum uses hydroxypinacolone retinoate (HPR), a retonic acid ester. This product is related to retonic acid: a compound derived from Vitamin A that helps stimulate collagen production, hydrate your skin, and smooth wrinkles. HPR plays a similar role but with one major advantage: it may help you reduce visible signs of aging without irritating your skin!
