An ideal introductory retinal serum to plump and tone the skin. This formula contains retinaldehyde which is a revolutionary new form of vitamin A that targets fine lines and wrinkles, pigmentation and uneven skin texture. Proven to work up to 11 times faster than retinol, and is absorbed gradually into the skin overnight, reducing irritation. Combined with hydrating hyaluronic acid and skin-soothing vitamin E, Crystal Retinal 3 targets fine lines and wrinkles for smooth and visibly youthful skin.
