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.

Key Ingredients:

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 1 out of 5 by from Fabulous Product I have been using Medik8 retinal for a number of years. I am regularly complimented on the youthfulness and appearance of my skin and I feel this is mostly down to this product along with a regular skincare routine. Easy to use lovely consistency and a reasonable price.

Rated 5 out of 5 by from Fantastic product After finishing my first tube of Crystal Retinal 3, I can confirm that it is a fantastic product and I am not going to move onto the Crystal Retinal 6 I was previously using a monthly subscription retinol which was great for my spots but I just couldn’t get through the dryness and discomfort. I had heard great things about Medik8 so decided to try and ease my way in by starting on number 3 It has kept my spots at bay and I have suffered from no dryness or discomfort Fantastic product

Rated 5 out of 5 by from Amazing product Completely cleared up my skin , I know it’s not supposed to be an acne product but since I have been using my skin has been so clear & decongested- it’s gave me the best skin of my life. I have quite sensitive skin & started on level 3 , just finished my level 10 and my skin is worlds away from the start! Highly recommend this product

Rated 5 out of 5 by from Skinvestment that works If you’re fed up of buying and trying anti aging products with limited success, buy this, buy it now and chuck everything else in the bin. This works like nothing I’ve ever tried, my skin is more even in tone and texture, fine lines diminished and all achieved with zero irritation. Just buy it, I can’t recognise strongly enough.

Rated 5 out of 5 by from Reliable Retinal I’ve been using Crystal Retinal by Medik8 for the past few weeks, and I can confidently say it lives up to the hype. As someone who has tried various forms of retinoids—from over-the-counter retinol to prescription tretinoin—I was skeptical about how effective a “gentle” retinaldehyde formula could be. But this product struck the perfect balance between efficacy and skin tolerance.
