After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.
For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.

A true breakthrough in vitamin A skincare
When it comes to vitamin A; the more stable the molecule, the more effective it can be on the skin. Crystal Retinal offers a level of retinal stability that can only be found at Medik8.
Our innovative stability system features our renowned crystal encapsulation technology, a patented carrot seed oil complex, and airless packaging. All this comes together to protect the retinal molecule for unmatched potency, long-lasting effectiveness and proven skin comfort.
Unlike many retinals, which can cause flaking and irritation, Crystal Retinal has been expertly formulated in our in-house laboratory with a unique combination of the highest quality ingredients and patented technologies so it's gentle yet very powerful.
Addressing 90% of age-defying skincare needs*, we especially recommend using this product alongside our industry-leading vitamin C and sunscreen formulas - as per our pioneering CSA Philosophy.<br>
