Transformative!

This is truly so effective on my skin. I've used lower doses for years and this was the perfect upgrade which I will stick with for a while.

Lovely!!

I don't think I've bought any medik8 product and not liked it!!! Perfect formula. No irritation at all.

So far so good

Have been using for 2 weeks and normally use the ‘Youth To The People’ retinal. Can’t really say if I can notice a difference visually but the cream is a nice lightweight texture, it didn’t cause any reaction on my dry, aging, sensitive skin. I’m used to retinal so maybe will go to the higher strength next time. Only thing is my YTTP bottle will last longer as the tube seems quite small.

Medik8 retinal 6

Slowly working my way up the different strength retinal in the range. This is the next step up and still delivers a soft skin feeling with much less irritation than the other types of retinol I’ve used. Would recommend starting at 3 and working up.

Brilliant

This is my favourite 'retinol' it is much more gentle on my skin than others that I have used and also adds good hydration and glow to the skin. I have been using this product for about a year and I have definitely seen an improvement in fine lines and the texture of my skin.
