Hydroxypinacolone Retinoate (HPR) is a revolutionary new retinoid. Compared with other vitamin A products, it can directly work through the excitatory receptor without metabolic transformation (generally retinoids need to be transformed in the skin in two steps). It is less irritating, highly potent, more stable, and less likely to be oxidized. It is a safe and effective anti-aging (effective in reducing fine lines and wrinkles, fading color spots) and anti-acne ingredient. Hydroxypinacolone retinoate, a derivative of retinol, regulates the metabolism of the epidermis and stratum corneum. It can be anti-aging, reduce sebum overflow, desalinate epidermal pigment, and play a role in preventing skin aging, preventing acne, whitening and lightening spots. It can be used to treat skin diseases.
