Good product

Holy grail

My holy grail retinol, one of the best you can buy in my opinion. I also love that you can increase the strength of your retinol as your skin adjusts to it. Wear spf everyday if you use retinol!

Incredible

So long as you read the instructions and use this sparingly / build up your tolerance- this is incredible. It's helped my skin texture so much and it's wonderfully moisturising

Good for sensitive skin

I’ve used medical grade retinol but it was too strong for my skin. I started out with this one from Medik8 and it’s not irritated my skin at all or caused excessive peeling. I will be moving up the the higher strength once I finish.

Great gentle retinol alternative

I really love this range - active ingredients that are gentle on sensitive skin and at a relatively decent price. I never have sensitivity issues with Medik8 products and this cream is an ideal alternative for those like me who struggle to use conventional retinol

Never Disappoints!

I can’t believe I waited so many years to try the brand. I started with Medik8 Crystal 3 and now upgraded to the 6. I’m also using their Liquid Peptides and the results are amazing! Will keep repurchasing!

Only thing thats worked

I've tried everything to sort out my acne. I really didn't want to have to take medication, but has worked wonders for me and now had breakouts under control.
