Description
Powered by retinal, a next-generation form of vitamin A that works 11 times faster than standard retinol, Crystal Retinal accelerates visible skin renewal for transformative age-defying results. Medik8’s patented retinal stability system ensures unrivalled potency and performance right down to the final drop.
With consistent use, skin appears clearer, smoother and more radiant, with a firmer and more youthful texture overall.
It’s no wonder Crystal Retinal is the UK’s No. 1 dermatological face serum.
How to use
Step 1: After cleansing in the evening, apply two pumps of Crystal Retinal to the face and neck. Allow to absorb, then follow with a moisturiser such as Medik8 Advanced Night Restore, designed to be used after vitamin A. Step 2: If you’re new to Crystal Retinal, introduce gradually: use twice a week for the first two weeks, every other night for the next two weeks, then nightly. Always apply sunscreen the following morning.
We recommend finishing one tube of your current Crystal Retinal strength before progressing to the next level.
