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

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 Unfortunately I didn’t notice any [This review was collected as part of a promotion.] Unfortunately I didn’t notice any improvements using this. I had such high hopes as well. The colour (orange) comes off on everything too so not ideal. Was a lot of money for something that sadly didn’t work.

Rated 3 out of 5 by from It is a good product for those new to retinoids It is a good product, but to mild for me. . I still use it but need to add more potent products intermittently. I've been using 0. 1% Retinoid, which is best for me, but possible to strong for some.

Rated 1 out of 5 by from Just more skin problems I have tried this with all the recommended ways to put but i keep getting more spots and skin issues unfortunately my moneys wasted 🥲

Rated 5 out of 5 by from It’s magic I’ve been buying and using this for a year now. It’s transformed my skin, and I had quite nice skin to begin with at 33. I put this on and then let it sink in for a few minutes and follow with moisturiser, an hour before bed so it doesn’t just wipe straight onto the pillow. My skin is so smooth, even toned with redness gone (hallelujah), not as dry (I suffered with very dry skin during winter), it looks plumper, and people notice and comment on it. It’s given me glass skin. It’s pricey but worth the money in my opinion and I don’t have any cosmetic procedures like Botox etc whilst a lot of women I know do. That’s far more expensive in comparison. However, I didn’t have many fine lines or wrinkles to begin with, so it’s difficult to measure it’s effect there.

Rated 5 out of 5 by from Amazing [This review was collected as part of a promotion.] Absolutely beautiful product when I put it on my face it just smells gorgeous so easy to use and it hasn’t made a massive difference to my skin. Highly recommended. There’s so much skincare to choose from these days but I would highly recommend this brand.

Rated 4 out of 5 by from Too soon to tell It is probably too early to tell since I have only been using this product for about four weeks . I followed the instructions so didn’t see any adverse reactions . My skin did break out a little but this settled again soon . I haven’t noticed any major differences so far (I have combination skin with minor wrinkles and some sun damage) but will keep using this anyway and then perhaps try a higher concentration .
