Hydroxypinacolone Retinoate, also known as HPR, is a next-generation retinoid that exhibits exceptional skin rejuvenating properties. It is a derivative of retinoic acid, a form of vitamin A known for its ability to promote skin renewal and improve overall skin texture. With its small molecular size, HPR penetrates the skin more effectively than traditional retinoids, making it an ideal ingredient for targeted treatment of hyperpigmentation and fine lines.
