Medik8’s iconic night serum, now with a 0.2% concentration of vitamin A. Crystal Retinal 20 is a clinically-proven formula that works over time to diminish visible signs of ageing. At the core of its composition is retinaldehyde. This revolutionary form of vitamin A helps to minimise the appearance of fine lines, pigmentation and textural irregularities, while lending the skin a firming effect. Helping to minimise feelings of dryness and sensitivity post-application, the serum is blended with hyaluronic acid, glycerin and vitamin E for a refreshing boost of hydration. These ingredients are supported by Medik8’s patented stability system to ensure maximum potency and effectiveness. Crystal Retinal 20 is the strongest treatment in the complete collection. It is only recommended for experienced vitamin A users who have comfortably finished two tubes of Crystal Retinal 10.
