Wow

I had a retinoid (The Ordinary) that I thought was great, visible results and a great price point. However this is next level results. My skin is fairly hardy, so I didn’t get any adverse reaction from using the product. It’s in a nice creamy serum formula which i much prefer to oils.

Incredible

I cannot recommend this serum enough. It’s simply gorgeous. Beautiful scent, velvety, glides on skin like a dream and absorbs quickly. I’m on my third tube I enjoy it every time I use it. My acne is 70% better, my scarring and hyperpigmentation less and it’s already working hard on those wrinkles. I use many medik8 products and they’re a rare brand that does what the say. I’ll never be without it now.

The BESt

Hands down, this is the best Retinal I’ve ever used! I started with Crystal 1 and have worked my way up through the system.  I’ve periodically brought and tried alternative Retinals but ALWAYS return to Medik8 Crystal. For me, it doesn’t get any better- I’ve recommended to all my friends and family, who also purchase and are converted

Simply the best

I've just moved up to CR6 from CR3 after trying a different retinal inbetween. I think Medik8 is the gold standard when it comes to retinal. It sinks in easily and even though I have moved up in strength I have had no irritation. My skins loves it. It's one thing I am happy to prioritise spending a bit of extra money on

Lovely texture & results

I stepped up from using CR3 to CR6, and I have sensitive skin, but I didn’t see any irritation. It’s a lovely texture and scent. Keeps my skin clear.

Beautiful product

Been using this for a few months at night and I can see the difference in my skin. The texture is creamy but absorbs well with no stickiness. It's expensive but you only need a small amount. A great addition to my Medik8 routine!

Sunspots

I am building my way up the strengths on this and have found it to reduce the appearance of hyperpigmentation. It also makes my skin look more youthful and is absorbed easily

Love love loveee

My favourite retinal! I’ve tried pricier options but I love this! Soft scent, smoothing cream like product instead of an oil or serum! Will be repurchasing
