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.

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 This product has completely transformed [This review was collected as part of a promotion.] This product has completely transformed my skin. From the first few weeks of use, I started noticing smoother texture, and an overall radiant glow that I’ve never had before. As a new user, I was worried about irritation or purging , but the formula is so well-crafted that I experienced minimal flaking or redness. It’s the perfect introduction to vitamin A for anyone new to retinal. The texture is creamy and luxurious, and it absorbs quickly, leaving my skin feeling hydrated and nourished. I wake up every morning with skin that looks fresher, clearer, and more even-toned.

Rated 4 out of 5 by from Smoother skin! [This review was collected as part of a promotion.] I am enjoying using the Crystal Retinal products and my skin is certainly very smooth, it will probably take longer to remove the wrinkles but fingers crossed.

Rated 5 out of 5 by from I was wow'd by this anti-aging miracle. I received the sample and was eager to try it that night! I clesned my skin as advised and applied the serum to my face and neck avoiding my eye areas. Within seconds i could physically see with my own eyes the cyanges to my skin and my mouth fell open with a suprising shock! It worked that fast! Of course tĥe effects were still there the next morning when i did my daily double cleanse tĥat was! My skin reverted back a little to what it had previously looked lije, but i was vety keen to use itcagain and again! I have since bought this nagnificent serum even though i have only used the sample 2 times before i went ahead and bought the next strength up from the number 6 which the sample was. Now i am ready to carry on my journey of discovery for my 67 year old skin! Boy am i glad that i have gone ahead and boutht the number 10 strength! Yes i am a regular retinol user and to begin usingvthe sample i had sstopped using my previous retinol of choice 3 days before i began using tĥe sampĺe. Friends arexasking me what am i using as i now look around 20 years younger tĥan isctually am! Thank you Medik8!

Rated 5 out of 5 by from Love it [This review was collected as part of a promotion.] Perfect retinal solution - gives you even skin tone, no irritation

Rated 5 out of 5 by from Perfect Retinal [This review was collected as part of a promotion.] I love the crystal retinal products! I have worked my way up and am now using 20. I love how even at this strength there is no irritation, only slightly on the first week of the new strength. This product has really helped to control my hormonal acne and also reduce/keep at bay any fine lines I was starting to notice! Would definitely recommend this to anyone wanting to start their retinal journey or even increase strength without irritation!
