Love it!

I really like using this retinal ! I will definitely be repurchasing it when it gets low! There was no irritation at all n very little peeling the first time I used it ! I’m excited also to try the 2.5  when my skin has fully adapted to this one! Which it pretty much has since the first use! Def recommend this to ppl who have worked their way up already

Powerful Yet Gentle Rentinol

I was so excited when I saw that Medik8 came out with an even stronger version of this serum. I continue to have glowing skin with minimal irritation because of the great formulation here.

Gentle

I’ve tried Tretinoin and just can’t get through the purge. This is non irritating and as close to pure retin A as I am use. I like it. I have very mature, dry skin and this does not cause any additional dryness. This is my second tube of this strength and I will purchase more.

Must have product

This serum has fully changed my skin. I had some fine lines before, nothing crazy but definitely was something I wanted to get rid of. This serum has done exactly that, my forehead is completely smooth, I don’t have smile lines or crows feet, it really has done exactly what I needed and more. If I were to lose every product I own, this would be the first one I would repurchase, worth every penny and can’t recommend enough!

Sensitive Skin

Best retrinal/retinol for sensitive skin. Fades dark spots and helps skin texture look smooth and firm!

Medik8 Crystal Retinal 20

I have used the Medik8 Crystal Retinal 10 without any side effects and decided to upgrade to the Medik8 Crystal Retinal 20. I have found this to work well on my neck leaving it smooth and firm. However, I find it too harsh for my face causing redness. I will continue to use the amount that I have left on my neck and switch back to the Medik8 Crystal Retinal 10 when finished.

Zero irritation

This is the strongest strength sold by Medik 8 and it has been great. No irritation and smooth  bouncy skin.i definitely recommend if you have been using retinol for years. I think I maybe ready for proscription Tretinoin.

Zero irritation, highly effective

Fist off seasoned retinoid user . This was easy to incorporate used nearly ever evening since purchase with zero irritation. So glad to see Retinal at this strength for consumers like me who have enjoyed results from lower strength but hit a plateau and do not want to go down the proscription route.If this is you buy it. New to retinol users it’s a no. Derms always recommend start low and slow. Price is not outrageous bought on sale. Will repurchase.
