Formulated with retinaldehyde, a super-charged derivative of vitamin A, Crystal Retinal™ works with the skin’s natural mechanisms to enhance collagen production and speed up cellular turnover. Works up to 11x faster in the skin than classic forms of retinol. This ground-breaking night serum cream firms, plumps and resurfaces the skin, visibly minimising the appearance of fine lines and wrinkles to deliver a healthier, more youthful, even-toned complexion. Featuring multi-weight hyaluronic acid and vitamin E, it hydrates the skin at every level whilst strengthening the skin’s barrier to keep moisture locked in tight. Lightweight and luxurious, Crystal Retinal™’s silk-like texture sinks effortlessly into skin to nurture and restore the complexion. You explore the rest of our Medik8 product range here.
