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:
Retinaldehyde
Retinaldehyde (retinal for short) is a revolutionary form of vitamin A that is clinically proven to work 11x faster than traditional retinol* to address the appearance of fine lines and wrinkles, uneven skin texture, loss of firmness and hyperpigmentation without any irritation.
*G. Siegenthaler et al., Retinol and retinal metabolism, Biochemical Journal, 1990, 268, pp 371-378

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 Retinol I apply this as part of my night time routine after cleanse and tone. Sometimes I throw liquid peptides in and then moisturise. My skin looks and feels great.

Rated 5 out of 5 by from Crystal Retinal I have been using for about a month with other Medik8 products and am a convert to the brand. Skin is noticeably brighter and this has been noticed by friends and my husband. I will be moving up to the next level once this tube is finished. Packaging could be less

Rated 5 out of 5 by from Fantastic! Love this product, it is pricey but I feel it is worth it. I am getting on in years but still think that any product from you is well suited to my skin type and people do comment on how I look for my age. Thank you

Rated 5 out of 5 by from Must have product Started this product a couple of years ago and have slowly worked my way up. Can’t be without it now! It has cleared my fine lines, dark areas, rough skin and helped open pores. An absolute hero product to add to your routine.

Rated 3 out of 5 by from Drying to the face I like this product, but it is very drying on the skin and feels as if you’ve just put concrete on your face. I am unsure if your meant to follow it by putting a night moisturiser on top
