Great but pricey
I got this as part of the 2023 advent calendar and I didn't read the instructions properly at first. You need to build up your tolerance a bit and use it every few days at first. It tingles when you first use it but your skin will get used to it. I thought this was actually really effective and I noticed a difference after using this tube.
Best Use: Reduce Puffiness, Uneven Skin Texture, Firming, Anti-Aging

the best
Hands down the best retinal on the market! I just can’t get enough of it. I started with CR3 and quickly moved to 6. It doesn’t cause any irritation, the texture is lovely and absorbs beautifully into the skin. I pair it with Advanced Night Restore moisturiser and my skin is so soft, smooth and youthful-looking in the morning.
Best Use: Treat Pigmentation / Dark Spots, Treat Redness, Reduce Dullness, Minimise Fine Lines & Wrinkles, Uneven Skin Texture, Firming, Anti-Aging

Fab
Big fan of medik8. I use the vitamin C and have heard great things about this product. Gave it a go and my skin feels really soft, plump and no spots and have had several compliments. Would recommend to anyone consider this or this brand. Will definitely repurchase

Too good to be true
Medik8 Crystal Retinal 6 is truly a game-changer! Initially, I was skeptical as the claims seemed too good to be true, but after using it for a few weeks, I am amazed by the results. My skin has never looked better - smoother, clearer, and more radiant. This product is definitely worth every penny!

Unhappy so far…
I have only used the product once so far so cannot give a review of the results yet however so far I am unimpressed, I bought this on offer for £55 and for 30ml personally I think that’s very expensive and it is three quarters full, I had to pump over 20 times to finally get any product. Considering it’s a premium brand I expected it to be full.
