Vitamin A skincare reinvented. Crystal Retinal is a powerful night serum proven to work 11X faster than Retinol products.

0.06% Retinal serum for regular vitamin A users - 11x faster than retinol

Discover youthful skin with Medik8 Crystal Retinal, the ground-breaking serum that reinvented vitamin A skincare. Featuring retinaldehyde, the next-generation retinoid that is 11x faster acting than retinol[1], now available in a series of 5 progressive strengths to accompany you on your journey to Beautiful Skin For Life.

Crystal Retinal is our ‘everyone’ vitamin A. It is renowned for its universal hydrating texture and low-irritation potential, while delivering profound, proven age-defying results.

Extremely sensitive skins should start low on Crystal Retinal 1 (0.01% retinal), with Crystal Retinal 3 (0.03%) best for sensitive skins or for those nervous about using retinal. Most people can start on Crystal Retinal 6 (0.06%) and gradually move up to Crystal Retinal 10 (0.1%) & 20 (0.2%) for clinical-strength results.
RetinOl is two conversion steps away from active retinoid ‘retinoic acid’, whereas retinAl is just one step away. So you get faster, elevated results.

Retinal improves all of the visible signs of ageing 11 times faster than retinol[1].

Unlike other forms of vitamin A, our Crystal Retinal formula is suitable for even the most sensitive skins.

Retinal is the only form of vitamin A with antibacterial properties, making it perfect for oily or blemish-prone complexions.
