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.

Rated 4 out of 5 by from Best retinal on the market [This review was collected as part of a promotion.] I’ve been using this for over 2 years now and omg have I seen my skin change, for the better! My complexion is brighter, smoother and has smoothen out my fine lines. My sling can be quite sensitive but I introduced this low and slow and have built it up over the last 2 years and my skin has never reacted. I will never stop using this!

Rated 5 out of 5 by from Good Nice product texture and smell. Has not irritated my sensitive skin. Have had some compliments this month since using so seems to be doing the job.

Rated 5 out of 5 by from Good I have sensitive skin but I’m trying to get into retinol for fine lines and to grow old gracefully. The pump works well and dispenses the right amount. The cream goes on smoothly and feels nice. I’ve followed the advice - twice a week for 2 weeks and then every other night for 2 weeks, so just going into using it nightly. I had very slight dryness initially, but as I said I have sensitive skin that rebels whenever I use something new. I’m planning to move up through the levels so hoping I’ll see the long-term effects of this.

Rated 5 out of 5 by from It works [This review was collected as part of a promotion.] I didn’t believe that it was working, but when I tested it I was surprised. The skin looks amazing, the ton of skin very smooth. I just started using #3 more details will be able to say later when get it all.

Rated 5 out of 5 by from Fabulous product. [This review was collected as part of a promotion.] I have used retinol for a long time and I have swapped between brands to try and get the perfect one, well I’ve now found it finally…better late than never! I start my journey with crystal10 which I felt was the right starting point for me and it’s working beautifully my skin is softer and more glowing than it’s ever been so the 10 strength product was right for me, I will move up once I have finished a second tube, it’s hard to tell how much is in the tube and sometimes it’s a struggle to get the product out so I will order one as a back up cos I literally do not want to run out. I have Botox regularly and went last week and was asked what I’d been using as my skin was looking really lovely and there was no need for my Botox in my jaw areas as it seems to be tightening all by itself ( ok so not all by itself) so money saved on that. I’ll be interested to see in a few more months how my skin progresses but I feel my skin looks the best it’s looked since I was in my early 40’s thank you MEDIK8.

Rated 5 out of 5 by from The best [This review was collected as part of a promotion.] Have loved working my way up the retinal range. Haven’t had any irritation with any of them and really notice the difference in the condition of my skin. I pair this with the eye serum. I do feel like retinal & spf are the best and keeping your skin looking young & at its best. I am a repeat buyer of retinal & love working up the range.

Rated 5 out of 5 by from Unfortunately I didn’t notice any [This review was collected as part of a promotion.] Unfortunately I didn’t notice any improvements using this. I had such high hopes as well. The colour (orange) comes off on everything too so not ideal. Was a lot of money for something that sadly didn’t work.
