Product Description

Reveal visibly firmer, brighter-looking skin with just 1 tube of Crystal Retinal.

Medik8’s bestselling vitamin A night serum is formulated with next-generation retinaldehyde (retinal) which is clinically proven to act 11x faster than retinol* for a visibly brighter, smoother and firmer-looking complexion.

Unlike other retinal serums available, Crystal Retinal features Medik8’s unique patented stability system to ensure maximum retinal potency, while their industry-leading encapsulation technology delivers powerful yet gentle results with minimal irritation, even on sensitive skin types.

Loved and recommended by dermatologists and professionals all over the world, Crystal Retinal features a unique ladder of 5 progressive strengths (0.01%-0.2% retinal) so that you can continue to experience increased visible youth-renewing results. If you’re a vitamin A beginner, Medik8 recommends that most people start on Crystal Retinal 3 (0.03%), or Crystal Retinal 1 if you have very sensitive skin (0.01%). If you’re an experienced vitamin A user, start with Crystal Retinal 6 (0.06%) and gradually work your way up to Crystal Retinal 20 (0.2%). To use Crystal Retinal 20, you must have comfortably finished at least 2 tubes of Crystal Retinal 10 due to it containing a high percentage of retinal.

Working to reduce the appearance of stubborn fine lines and wrinkles and dark spots, Crystal Retinal is the ultimate age-defying serum for a healthier, more youthful-looking complexion.

Hyaluronic Acid
An incredibly hydrating ingredient, hyaluronic acid attracts and retains more than 1,000 times its own weight in water and draws moisture in the upper layers of the skin; leaving it looking visibly supple and deeply hydrated.

Vitamin E
Rich in antioxidants, vitamin E helps to protect the skin against ageing free radicals, while helping to stabilise retinal for maximum results.

Glycerin
A natural humectant that locks moisture into the skin; leaving it feeling comfortable and hydrated.

Directions

- After cleansing in the evening, massage Crystal Retinal across the face, neck and décolletage.
- Allow to absorb before applying your moisturiser.
- Crystal Retinal application should be phased in gradually, and only use in the evening.
- 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.

Rated 5 out of 5 by from Crystal Retinal Up until now I haven't been able to get along with retinols for one reason or another but, as time has gone on and the lines are deepening, I thought I would try again. After reading lots of reviews, of the Crystal and others, I decided on Medik8. So easy to use, smooths onto skin and disappears. No after touch. Have been using for 3 weeks now, starting off as recommended and building up to nightly. As yet no irritation. No huge difference, as yet, in my lines, but it is early days.

Rated 5 out of 5 by from Crystal Retinal Magic indeed really helps keep signs of aging at bay. My first retinal product and one that I renew without fail.

Rated 5 out of 5 by from Something I've wanted to use for a while After recently listening to skincare experts who recommended at least a basic routine, I decided at 40 (male) to maybe start giving it a go. And I'm glad I did. Skin has broken out into spots which i never get but googling retinoids I'm told this is common when you first start. No noticeable results yet as it's only been a month but I'm told it could take months so I'll certainly be monitoring as it's not a cheap gig!

Rated 4 out of 5 by from Crystal Retinal 3 A thicker vitamin A than I have been using, so more of a cream than a serum. Since first use I have experienced no stinging, redness or dryness to my skin and would say skin looks and feels plumper and smoother. It’s early days and I need to use for longer to see the longer term benefits, but I am impressed so far.
