strength ladder Zoom In Icon

Ladder up your visible age-defying results over time with Crystal Retinal's 5 progressive strengths (0.01% - 0.2% retinaldehyde) - only available at Medik8. For those with very sensitive skin, we recommend starting with Crystal Retinal 1 (0.01%). However, most Crystal Retinal and vitamin A beginners start on Crystal Retinal 3 (0.03%). If you're an experienced vitamin A user already, start at Crystal Retinal 6 (0.06%) before working your way up to Crystal Retinal 10 (0.1%) and finally Crystal Retinal 20 (0.2%). Not sure which strength is right for you? Take our simple quiz to find out.

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 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%).

KEY INGREDIENTS
Circular Chevron Icon
  • 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.

  • Ingredient Icon 2
    Hyaluronic Acid

    With the ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the upper layers of the skin; leaving the complexion hydrated and visibly supple.

  • Ingredient Icon 3
    Vitamin E

    A powerful antioxidant, vitamin E works to protect against the ageing effects of free radical damage while stabilising retinal for optimal power.

  • Ingredient Icon 4
    Glycerin

    A natural humectant which traps moisture within the skin to leave it hydrated and comfortable.

THE SCIENCE BEHIND THE FORMULA
Circular Chevron Icon
science behind Zoom In Icon

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.
