Love!

Love this product.  Like most people I started on number 3 and then moved up to 6.  My skin looks so much more clearer and feels smoother since using this.

I love this brand!!

My absolute favourite skin care brand. It isn’t cheap but I genuinely feel that using this product has made a difference to the texture of my skin. I use this with their liquid peptides and have been for sometime and can honestly say my skin looks smoother

Love this

I've moved up from strength 3 after finishing my last bottle. I've barely had any irritation and my skin is glowing.

Fantastic retinal product!

I’ve been working my way up the Medik8 CR products, starting on CR 3, and have now moved on to CR 6 - fantastic product. It soaks in well and leaves me looking refreshed on the morning. Personally I’ve not experienced any sensitivity or irritation with the CR products, and have loved them so far.

Great Quality

I have very sensitive skin that I have had to build up to using stronger retinol products over several years, but I still have to be very careful. This retinal has caused me no issues at all, my skin is comfortable after use and not dried out or sensitive at all. The results are definitely showing and it lasts a long time too!

Best thing I have purchased this year 🤍

Thanks to TikTok where this product was recommended so I decided to give it a ago. I’ve been using this product for 3 weeks now but I’m going throw the purge stage, I would get crazy red spots or white heads out of no where and within 2 days it will disappear as well. The cycle is unreal.  I have notice a sight change I know it’s early but this works wonders. PS if you have acne use this, sort out your diet and exercise ( great for inflammation) , that’s the key not all of these expensive products trust me as I was on accutane for years but the second I stoped it all started all over again

conflicted between Retinal 3 and Retinal 6

Been using Nr3 for ages and I absolutely loved it, I thought it's time to try stronger Nr6. And Honestly didn't see much difference besides huge price difference. I will try Nr10. Maybe it will do better,  but if you are using Nr3 IT"S THE BEST! CHEAPER! SAME RESULTS. I would stick to Nr3...
