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

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.

How to Layer Crystal Retinal
PM: In your evening routine, first cleanse and apply your target serum. Follow with Crystal Retinal and finally, your moisturiser.

Rated 3 out of 5 by from Jury is still out I have only been using my first Retinol 3 product for 4 weeks. Can't say i'm noticing any marked difference yet. 1 pump action doesn't quite give me enough for my whole face, so being frugal with it.

Rated 5 out of 5 by from The Most Effective Skincare Product I’ve Ever Used I’ve been using Crystal Retinal® 6 and absolutely love it — I’ll definitely go for a stronger level next time. My skin looks clearer, smoother, and noticeably firmer whenever I use it. I pair it with Press & Glow®, and the combination works beautifully. I apply it every other night because I’m cautious about overusing retinoids as I’m planning a pregnancy, but even with that schedule, the results are amazing. I haven’t experienced any irritation or redness, unlike some people mention. I usually need about three pumps per use to cover my face and neck, so I suppose one tube will last around two months if used every other day. That makes the product a bit pricey to me — especially considering the higher cost of stronger versions. This is honestly the most effective skincare product I’ve ever tried. I’ve used retinal serums from The Ordinary and Olay before — they were good, but nowhere near as powerful as this one.

Rated 5 out of 5 by from Worth the wait… In four weeks my skin has transformed. From the very first use, I noticed a difference in my complexion, it was brighter. At the end of week two the difference was noticeable. I have been battling melasma for over a decade and have used every product on the market without success. Today, almost five weeks in, Medik8's crystal retinal has changed everything; my skin is clear and, bright. With continued use I'll be able to go makeup free. Beyond satisfied. 😊
