Moved up from the 3, with no irritation
I used up a tube of Crystal Retinal 3 before moving up to 6 as advised by the brand. I’ve found no irritation with the higher strength cream and I can see the continued improvement and refinement in my mid-30s skin. Pigmentation is clearing and my skin does look more even toned. Highly recommend this range of retinol over many others which I’ve tried. I have combination skin and find it best to apply the cream and then a moisturiser to add some hydration.

Good step up
I started using retinal products with the Medik8 crystal retinal 3 and was really pleased with the results and have now moved up to the crystal retinal 6. This is an ideal way to get yourself accustomed to retinal and to to build up slowly towards good results without upsetting sensitive skin.
Best Use: Brightening, Anti-Aging

Medik8 crystal retinol 6
I’m a fan of medik8 products and this retinol is just lovely. I have been using retinol for a couple of years hence the use of no 6. I apply it before the medik8 advanced night cream and in the morning my skin is smooth soft and well rested. I am lucky that I have very few wrinkles but I can definitely notice a difference.

Brilliant retinol without irritation
I’ve recently upgraded from Crystal Retinal 3 to number 6 and I’ve had no irritation with the stronger product. These serums show noticeable results with consistent use - skin looks more refined, brighter and pigmentation is kept under check. The product absorbs easily and skin is not left feeling stripped or raw. I’d suggest a nice moisturiser on top especially if you have dry skin. I’d highly recommend and will keep moving up the strength scale.
Best Use: Wrinkles, Hyperpigmentation, Brightening

I’ve been using this brand for over a year now and love it. I started on the lower strength first then bought the 6 to follow on with. My skin has adapted well to it. The consistency is lovely, goes on well and smells devine but not too over powering
