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.

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

KEY INGREDIENTS

  • 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.

    *G. Siegenthaler et al., Retinol and retinal metabolism, Biochemical Journal, 1990, 268, pp 371-378

  • 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.

  • Vitamin E

    A powerful antioxidant that provides additional antioxidant protection against the ageing effects of free radicals. It also helps to boost the power of vitamin C for optimum visible results.

  • Glycerin

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

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.
