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 The package arrived safely on The package arrived safely on time. I am using Crystal Retinal every night before going to bed. It feels so smooth and nice on my skin. In the morning my skin looks more radiant and youthful- I like what I see in the mirror. Of course the sleep routine is very important as well. I am very happy with decision to use Crystal Retinal. It is a great tool to take care of my skin

Rated 5 out of 5 by from Crystal retinal perfection Love this product! I initially bought it having received a sample tube of retinal 1 and enjoying the benefits. It smells so earthy and is a pleasure to use. If I had one small criticism, it's that it dries quite quickly, so you need to apply more. I found using a damp cotton wool pad immediately before applying helped it to smooth on evenly & saved me having to use additional pump of product. I purchased this product with the night restore cream & have found immense benefits in my skins appearance since using the products together.

Rated 5 out of 5 by from I have used Medik8 intelligent I have used Medik8 intelligent retinol for some years & decided to switch to advanced Crystal retinol because I felt my skin needed a boost. Think it’s too soon to see any real benefits yet, however the non greasy serum glides on and is absorbed quickly. Feels good.

Rated 5 out of 5 by from The best retinal on the market! I wish I knew about retinal earlier! Medik8 Crystal Retinal is smooth and glides on your face leaving you with soft textured skin. The well-designed tube/pump provides the right amount to be applied on the face.

Rated 5 out of 5 by from This product is amazing. Smells This product is amazing. Smells wonderful and it’s easy to spread. After a week my skin tone was more even and my face was brighter. Received lots of complements and honestly my skin tone has never been that even. Doesn't dry out the skin. I sometimes apply it and leave it for 10 minutes before applying moisturiser and my face is not dry. Best retinol product I've used, and I have used many. However, always use SPF the next day. I usually am religious with it, but one day I applied less than I'm supposed to and I burned so easily.

Rated 5 out of 5 by from So far so good. Was So far so good. Was very hesitant to use a retinoid product due to my sensitive, eczema prone skin, but I’ve had no issues so far using this twice weekly for 2 weeks. Feels lovely on the skin: looking forward to seeing the results after a longer period of use

Rated 4 out of 5 by from Definitely making a difference to Definitely making a difference to my fine lines. I was recommended this strength but think I should’ve gone for stronger as used to use Kate Somerville retinol before which was powerful too.
