HOW TO USE
Circular Chevron Icon
how to use Zoom In Icon

Step 1

After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturizer. We recommend Advanced Night Ceramide which is specifically designed to be used after vitamin A (retinoids).

Step 2

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.

We recommend using at least 1 tube of your current Crystal Retinal strength before moving up the ladder to the next strength.

THE SCIENCE BEHIND THE FORMULA
Circular Chevron Icon

A true breakthrough in vitamin A skincare.

DANIEL ISAACS Chief Product Officer

When it comes to retinoids; 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.
