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

- 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 5 out of 5 by from My Skin Has Never Looked Better! ✨ [This review was collected as part of a promotion.] I honestly can’t recommend Medik8 Crystal Retinal enough! It’s been the best retinal I’ve tried. My skin has improved so much — it looks smoother, brighter and healthier, and I’ve noticed a real difference in my fine lines, which are gradually fading. My skin feels so much more youthful and refreshed. I’m really impressed with the results and will definitely keep using it! ❤️

Rated 5 out of 5 by from Crystal retinal 3 [This review was collected as part of a promotion.] I have very reactive skin so decided to begin with strength 3 . I've had no reaction at all and have now progressed to strength 6 . . my skin loves this and it will be a permanent staple in my evening skincare routine.

Rated 5 out of 5 by from My Retinal Favourite for Years [This review was collected as part of a promotion.] I’ve been using Medik8 Crystal Retinal for several years now, after it was originally recommended to me by my cosmetologist, and it has become one of my favourite skincare products. I really like how my skin looks and feels when I use it consistently. It helps keep my skin looking smooth, fresh and healthy, and over time I’ve noticed an improvement in the overall texture and appearance of my skin. I also love that it feels comfortable on my skin and is easy to incorporate into my evening routine. After using it for several years, it’s definitely a product I trust and continue to repurchase. I would happily recommend it to anyone looking to introduce retinal into their skincare routine.

Rated 5 out of 5 by from Removing fine lines [This review was collected as part of a promotion.] I’ve been using the product for years now. Perfect together with peptide cream or restore night cream. In the morning the skin still feels hydrated and smooth. I always use SPF the following day as recommended. My fine lines are less visible and condition of the skin is smooth.
