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. The Crystal Retinal collection features a unique ladder of five progressive strengths (0.01 – 0.2%), and Crystal Retinal 20 is the strongest treatment in the range. It is only recommended for experienced vitamin A users who have comfortably finished two tubes of Crystal Retinal 10.
