Product Details

Stable Retinal Night Serum.

Rediscover youthful skin with Crystal Retinal™, Medik8’s latest innovation in vitamin A is now available in four strengths. Formulated with stabilised retinal, a powerful derivative of vitamin A with next-generation anti-ageing results. Unmatched in its age-defying power, retinal can deliver results comparable to clinical-grade vitamin A up to 11 times faster than classic forms of retinol.*

The ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face. Featuring hyaluronic acid, glycerin and vitamin E, it hydrates skin at every level to deliver a supple, even-toned, more youthful-looking complexion.

More than that, it actively helps reduce blemish-causing bacteria to keep skin clear and balanced. In just 4 weeks, skin is noticeably younger, smoother and undeniably radiant.**

Ladder up your results with 4 available strengths: 1, 3, 6, and 10. Most customers start on Crystal Retinal 3 (for skincare beginners) or 6 (for experienced skincare users), then over time move up to 10 if necessary.

Encapsulated Retinaldehyde – Proven to work up to 11 times faster than retinol, retinaldehyde is a revolutionary new form of vitamin A that targets fine lines and wrinkles, pigmentation and uneven skin texture.
Hyaluronic Acid – With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple.
Vitamin E – An oil-soluble antioxidant, vitamin E can quench free radicals on the skin while stabilising retinaldehyde for optimal power.
Glycerin – As a natural humectant, glycerin traps water within the skin to leave it hydrated and comfortable.

Will always repurchase.
I’m 26 years old and new to retinol, but work in the sun everyday and I have started to notice some fine lines appearing. I wanted to add retinol to my routine as prevention rather than cure. I have combination skin that can be sensitive but after and bit of research and heaving used AHA’s and BHA’s for a number of years I decided to go straight in with number 6. Followed by Medik8’s advanced night repair. Neither of which have disappointed! Even after the first use my skin felt brighter and more clear. It goes on and sinks in beautifully andI have had zero irritation from this product! Would 100% recommend if you’re looking for a quality retinol product that works fast.

This product is amazing. My skin is usually very sensitive but have not reacted at all. Am only 1 week of use and the benefits are beginning to show.

Favourite find
I swapped to this straight from retinol 10TR and I will never go back. This absorbs very quick and doesn’t leave this skin feeling oily. Personally I am also more of a fan with the way this one dispenses - however I know I will go through this quicker than the oil type one

So far so good
I was using The Ordinary Granactive Retinol, then Aspect Dr Exfol A+ (1% Retinol). Went straight onto CR6, face neck and chest, nightly, with no issues. Pleasant, mild fragrance. A thick cream consistency, rather than a lotion or serum. Obviously, too early to tell how effective CR6 is, that's why only 4 stars.

No Issues So Far
Upgraded a couple weeks ago from Aspect Dr Exfol A+, which has 1% retinol. Obviously still too early to tell how effective this product is, but I was able to go straight to CR-6 nightly, with no sensitivity. Has a mild fragrance and a cream rather than thin lotion or serum texture. So far so good.
