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.

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 I adore Crystal Retinal I am an experienced user, years ago started with the lowest percentage of Retinal, now using 20. Keeps my skin looking healthy and younger than I actually am.

Rated 4 out of 5 by from Will keep using Using this in combination with other products and nothing bad to say about it! Can't tell exactly how much effect it has by itself, but it feels like it also helps with light acne.

Rated 5 out of 5 by from Great product. would not use any Great product. would not use any other brand after using medik8

Rated 4 out of 5 by from I like this! This product has a lovely consistency and absorbs easily as part of my night skin routine. I feel my skin is very happy and I don't experience any irritation from the retinal which is a real bonus. I'm regularly told I don't look my age, so I assume this means the product is working! My only gripe is that the coral coloured product transfers onto my (white) pillow case which has not been my experience with the lower strength products (x6, x10 etc)

Rated 5 out of 5 by from Adding Crystal Retinal to my Adding Crystal Retinal to my evening skincare lineup has been a game-changer. I use it with Hydr8 B5 Intense and Advanced Night Restore and together they feel like a dream team for my skin. The serum itself is creamy and gentle no irritation, no dryness just smooth, radiant skin that keeps getting better. Since introducing it, I’ve noticed my skin looks more refined and even-toned. Fine lines are softer, and there’s a healthy glow that wasn’t there before. It’s powerful but surprisingly kind to my skin, which I really appreciate. I love how it layers perfectly with the other Medik8 products I’m using. The hydration from Hydr8 B5 and the nourishment from the night cream seem to amplify the retinal’s effects. It’s quickly become a staple in my routine, and I’m excited to see even more results over time.

Rated 5 out of 5 by from Best Retinol product I’ve tried I love this, saw results immediately and it’s continued to impress me. I was concerned that the tube is quite small but actually a little goes a long way.
