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 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.

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 retinoid that effectively targets the appearance of fine lines and wrinkles, dark spots, uneven skin texture and loss of firmness - without irritation.
*G. Siegenthaler et al., Retinol and retinal metabolism, Biochemical Journal, 1990, 268, pp 371-378

Vitamin E

A powerful antioxidant that's naturally present in the skin, Vitamin E works to nourish the complexion.
Glycerin

A natural humectant, glycerin attracts water to the skin to leave it hydrated, comfortable and visibly supple.

THE SCIENCE BEHIND THE FORMULA

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.

FAQS

When should I apply Crystal Retinal?

+
You should apply Crystal Retinal as part of your evening skincare regimen - after cleanser, toner and serums, but before your moisturizer.
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 physician or obstetrician 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 moisturizer?

+
We do recommend applying a moisturizer after vitamin A. Our bestselling night cream, Advanced Night Ceramide, is specifically designed to be used following retinoid use. It helps to boost the visible age-defying benefits of retinoids 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 optimized 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 per our Vitamin C + A strategy. This simple yet clinically proven skincare approach champions vitamin C 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). After cleansing in the evening, apply Crystal Retinal.
