Discover a younger-looking complexion with Crystal Retinal 1.
Featuring retinaldehyde (retinal), a next-generation form of vitamin A which is not to be mistaken for the classic form of vitamin A, retinol. In numerous studies, retinal has been demonstrated to be more effective and 11x faster-working than retinol, without any additional irritation.[1,2,3]
The hydrating overnight serum-cream visibly addresses signs of aging; improving the aappearance of wrinkles, texture and tone. Potency and optimum power is ensured through a double-layered stabilization system, which includes a crystal encapsulation that releases vitamin A gradually throughout the night, to protect the skin from becoming overwhelmed at any point. Hyaluronic acid and glycerin also feature to moisturize and hydrate skin, minimizing any dryness. The complexion is left visibly smooth and supple. Crystal Retinal is available in a series of progressive strengths. Crystal Retinal 1 (0.01% retinal) is the perfect starting point for sensitive skins before moving up to Crystal Retinal 3. Medik8 recommend a simple, effective skincare strategy of using vitamin C and sunscreen in the morning and vitamin A at night.
This strategy is called: CSA.

Gentle yet effective
I've always had a hard time with retinol-like products. Either they had no effect or destroyed my skin. This was the first I've used that was gentle yet effective. The consistency is nice too, it just soaks in. I'm now going to try the level 3- fingers crossed its the same.

Retanal 1
This was my first time using it, it smells great, I dont have sensitive skin so I didn't notice much of a difference, I will need to go up in number.

1st time retinol user
I started on this strength as it’s my first go round with retinol and I have very sensitive/acne prone skin. This stuff is INCREDIBLE. I have been using it for a month now and notice a difference in my acne scars and skin texture. Can’t wait to move on to the next strength(s)!

Best over the counter Vitamin A serum! Helps to fade lines and keeps the acne breakouts away. win win

Amazing!
This product is so so good! I’ve tried many retinols and they either look like they don’t do anything or they react to my sensitive skin. This one does neither of those! I am 26 and use it for my adult acne and it does such a good job at minimizing my break outs and keep my skin looking fresh. I absolutely love it. Highly highly recommend especially for retinol newbies

Happy first time retinol user
Did a lot of research before pulling the trigger on this product. Have super sensitive skin so have been cautious about starting a retinol. Am very pleased with product — absolutely no drying or negative side effects. My skin has always been good but recently have been battling some issues and I do feel that my skin tone especially has improved since starting to use. Will amp it up with the retinol 3 next.

Loving this product
It is so easy it is to get started with this retinal. Started noticing changes to my skin soon after using this. Can’t wait to slowly progress with this range of products.
