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 moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.

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.

Crystal Retinal 20 should only be used by those who have comfortably finished at least 2 tubes of Crystal Retinal 10, due to it containing a very high strength of retinal (0.2%).

  • Ingredient Icon 1
    Retinaldehyde

    Proven to work up to 11 times faster than standard retinol,* retinaldehyde (retinal for short) is a revolutionary form of vitamin A that effectively targets the appearance of fine lines and wrinkles, hyperpigmentation, uneven skin texture and loss of firmness - without irritation.

THE SCIENCE BEHIND THE FORMULA
Circular Chevron Icon

A true breakthrough in vitamin A skincare

Daniel Isaacs Chief Product Officer

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.
