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 5 out of 5 by from Great For Sensitive Skin! [This review was collected as part of a promotion.] I recently started using Medik8 Crystal Retinal strength 3 and I really love it, I can already see a positive difference in my skin. It is so soft and my fine lines are definitely blurred, I have also ordered and received strength 6 as my skin wasn’t at all sensitive to the 3 and will be starting to use it soon. My skin would normally be quite sensitive and i can honestly say the Retinal 3 was great. Hoping the 6 strength will be the same !

Rated 5 out of 5 by from I have only just started [This review was collected as part of a promotion.] I have only just started my skin care regime. I’m getting used to the products I need and in the right order but I can see the difference starting already. I have started with the 3 but I have already bought 6 for when this runs out. My skin is feeling softer and the fine lines especially on my forehead are getting reducing

Rated 5 out of 5 by from Another great product [This review was collected as part of a promotion.] I have worked my way through each of the products in terms of strength and I am loving the 20. My skin has responded very well to it and I am seeing a difference in my sun spots already.

Rated 5 out of 5 by from MARVEL [This review was collected as part of a promotion.] Marvellous from day one (or should I say night one). Smoothes skin, firms it, erases lines. I started 6 and now use 10.
Date published: 2026-04-07
Rated 5 out of 5 by from Fantastic product , works as promised - alternative to Botox to reduce lines and improve skin appearance [This review was collected as part of a promotion.] I was recommended this product by an Aesthetics clinician as an alternative to Botox to reduce forehead lines. It really works , i combine with the peptide cream. The number 6 is perfect but i tried the number 10 and it was too strong for me and dried my skin out. Honestly, this product is worth every penny but you must use consistently and also i use electrolytes & collagen supplements which also really help the appearance of my skin.
