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 Bought my second bottle. It took a few weeks for my skin to get used to this product, but once my skin had settled in I saw good results. My t-one is less oily and have an overall better complexion.

Rated 5 out of 5 by from Wake up with beautiful skin! Medik8 Crystal Retinal® is an impressive product that truly delivers on its promises. The texture is light and absorbs quickly, making it easy to incorporate into my nighttime routine. I've noticed a significant improvement in my skin's texture and overall radiance since I started using it. It’s gentle on the skin yet effective, and I appreciate that it helps with fine lines and uneven tone. I love waking up to refreshed and rejuvenated skin! Definitely a must-try for anyone looking to enhance their skincare regimen.

Rated 4 out of 5 by from Staining issues Yes I think it’s good. I am now on ret 10. I have noticed that if I use it every night my skin develops very dry and itchy patches so I use it every other night. Also, it stains my pillowcase and white duvet cover as it’s tinted.

Rated 5 out of 5 by from Crystal Retinal 3 I started with Crystal Retinal 3 and followed the instructions to start slowly and not had any irritation. Feels lovely on the skin and nice scent. I've only been using a few weeks but already I feel it is making a difference.
