Powered by 0.3% pure retinol, this formula utilizes advanced stabilization and delivery systems to provide a controlled, consistent release into the skin. To help prevent the irritation often associated with retinol, it is enriched with calming bisabolol. Housed in specialized packaging to maintain maximum freshness and efficacy, this formulation speeds up cell renewal to visibly smooth fine lines, fade discoloration, and clear blemishes. It can be used as a long-term daily treatment or as a stepping stone to build skin tolerance before graduating to SkinCeuticals Retinol 0.5.
