retinyl ascorbate

An ester of vitamin A (retinoic acid) and vitamin C (ascorbic acid) that functions as an antioxidant that seems to have a particular affinity for skin and its lipids, making it an effective topical option for improving skin's defense against environmental damage. This mix also shows greater stability in skin than when retinol or vitamin C are used alone.
