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.

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 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

Rated 4 out of 5 by from I feel too soon to I feel too soon to give full review. But I’m very happy that I’ve had no reaction as I have VERY sensitive skin and this was my first retinol. I’ve not noticed any change in my wrinkles or pigment over last month, but I’d say my skin texture has def improved. So I’m going to persevere and maybe slowly up the strength.

Rated 5 out of 5 by from Results are in I have been using this for a month so I’d like to think it’s too early for results, but the results are already in! The formula is beautiful, the texture rich and luxurious. Far nicer than other products I have used in the past! I have been building up resistance from 3-5 nights and there’s been no dryness or irritation. My skin is looking firmer and I’m really pleased with the results so far.

Rated 4 out of 5 by from Best I have used so far…. . This is a fabulous product and part of my favourite Medik8 range. Quality serum come cream which glides over my skin and absorbs readily. My skin has never felt to good and I intend to continue to use and work my way up strength range. I might feel my age at times but my complexion does not.

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 Great Product Smoother supple skin within 4 days of using this wonderful product. Visible results are usually not that obvious, but with Crystal Retinal night cream it was.

Asked by: Thera
If you have used retinal 3 for a while and your skin is okay with it, then yes I would say you can try 6.
