Crystal Retinal™ speeds up cellular turnover and increases the skin’s natural mechanisms for collagen production. Unlike other forms of retinol, it\'s formulated with a supercharged derivative of Vitamin A, retinaldehyde. This high-performance, retinaldehyde is an encapsulated active that only requires one conversion to retinoic acid, giving results comparable to clinical-grade and is up to 11x faster in the skin than classic forms of retinol. Medik8’s crystal encapsulation acts as a time-release mechanism as well as a stability enhancer. Retinaldehyde is encased within a crystal-shaped molecular vehicle that is gradually broken down by the skin’s natural enzymes as the serum is massaged into the skin. This unique action controls the release of the active to ensure the formula remains stable, absorption is optimised and the highly-potent formula is distributed evenly and consistently throughout the night. It features a multi-weight hyaluronic acid and vitamin E to hydrate the skin whilst strengthening the skin’s barrier to keep moisture locked in tight.
