HOW TO USE

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

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

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

THE SCIENCE BEHIND THE FORMULA

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.

FAQS

When should I apply Crystal Retinal?

+
You should apply Crystal Retinal as part of your evening skincare routine - after cleanser, toner and serums, but before your moisturiser.
Can I use Crystal Retinal every night?

+
As long as you build your use up gradually and start with the appropriate strength to begin with, you can use Crystal Retinal every night. For new users of Crystal Retinal, we strongly recommend that you phase-in application to enable your skin to build up a tolerance while avoiding any potential irritation. Use twice a week for the first two weeks, every other night for the following two weeks, then every night.
Can I use Crystal Retinal while pregnant or breastfeeding?

+
As a cosmetics company, we are unable to provide product advice in relation to medical conditions such as pregnancy or breastfeeding. We strongly recommend discussing the ingredients with your GP or midwife before use. We do, however, generally recommend avoiding vitamin A use while pregnant or breastfeeding, which is why we offer a plant-based vitamin A alternative - Bakuchiol Peptides.
Do I need to follow Crystal Retinal with a moisturiser?

+
We do recommend applying a moisturiser after vitamin A. Our bestselling night cream, Advanced Night Restore, is specifically designed to be used following vitamin A use. It helps to boost the visible age-defying benefits of vitamin A while maintaining optimal comfort.
Can I use Crystal Retinal around my eye area?

+
We don't recommend using Crystal Retinal directly around the eye area due to its very delicate nature. However, that's exactly why we've created Crystal Retinal Ceramide Eye. It boasts all of the renowned age-defying power of our original Crystal Retinal, but is expertly optimised for specific use on the delicate eye area.
How do I use Crystal Retinal alongside vitamin C?

+
We recommend using vitamin C alongside Crystal Retinal (vitamin A) as part of our pioneering CSA Philosophy. This simple yet clinically proven skincare approach champions vitamin C plus Sunscreen by day, vitamin A (retinoids) by night as the secret to youthful, glowing skin. After cleansing in the morning, apply your vitamin C serum (such as C-Tetra Luxe) and follow with your sunscreen (we recommend Advanced Day Ultimate Protect). After cleansing in the evening, apply Crystal Retinal.
