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.

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 5 out of 5 by from Pleasant experience and visible results Have been using Medik8 Crystal Retinal 3 for about 10 months - and it never disappointed. Gentle, non-greasy, non irritating (I've been diagnosed with blepharitis and dry eye). Light and pleasant. Goes well on niacinamide serum. On top of retinal I always put some nourishing moisturizer. I must say I applied it under my eyes as well - and most visible results appeared exactly in that area, the skin got firmer. Enjoyed the product. Time to move on to retinal 6.

Rated 5 out of 5 by from Liquid gold! I’m so annoyed I’ve only just found this liquid gold. It’s made such a difference to my face and because you can build the strength up I’ve had zero irritation or dryness. My skin looks more even, toned and my lines are faded. This is hands down the best anti ageing serum/retinal on the market (and I’ve tried a lot of them!) I will not be without this now. I know it’s expensive but you can’t put a price on your skin and this is an investment you want to make.

Rated 5 out of 5 by from Fine lines are visibly reduced I've been using Crystal Retinal 6 for a few weeks now, and the results are truly impressive. My skin looks noticeably smoother and more radiant. Fine lines are visibly reduced, and my face feels soft and refreshed every morning. It gives that healthy, glowy look that I was hoping for. Definitely a new staple in my skincare routine!

Rated 5 out of 5 by from The one and only I couldn’t fault this serum, ever. Started to use it almost 2 years ago, I am now at stage 10, so powerful, so good, I mean is anti aging weapon in a bottle. My skin looks so much younger and even like ever before. I’m so exited to start with 20 with my next bottle. My routine couldn’t be complete without Cristal Retinal.
