Crystal Retinal 20

Discover youthful skin with Medik8 Crystal Retinal, the one-of-a-kind, ground-breaking serum that reinvented vitamin A skincare. Available in a series of progressive strengths to accompany you on your journey to Beautiful Skin For Life.


Crystal Retinal is ‘everyone's’ 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.

Unlike other forms of vitamin A, 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.


Crystal Retinal is a one-of-a-kind innovation within the retinoid category. Not only featuring a patented stability system to offer unparalleled sustained levels of retinal power, Medik8 have taken it one step further and developed a progressive 5-strength ladder from 0.01% to 0.2% retinal. Harness the power of this molecule in a skin-friendly solution to build visible results comfortably over time.
