Usually love medik8 but this gave me a bad purge and undid all previous skin progress. Would recommend a weaker strength to start even if familiar with retinal.

Fantastic Product

5 stars out of a maximum of 5

As always Medik8 does not disappoint with their products. I recently moved up to number 6 after using 2 tubes of strength 3. The serum is lovely, absorbs well and I’ve never had a bad reaction to it. My skin looks noticeably better now than it did when I was younger and all the credit to that goes to these fantastic products!

Working so far

4 stars out of a maximum of 5

I started with a deluxe sample of number 3 before moving onto number 6 I’ve had a few spots which is to be expected when the skin purges, however I have been seeing results which I’ve never had with similar products, I have dry/dehydrated skin but this hasn’t made me sensitive at all and the only dry patches I’ve experienced are from after my spots have healed

With this serum my skin has become noticeably better, the skin turgor is denser.

Amazing

5 stars out of a maximum of 5

Received in an edit box and will definitely repurchase. I have used inexpensive Retinal and whilst they’re effective the formulation of this one is far superior.

Best Retinol. Full Stop.

5 stars out of a maximum of 5

I keep on coming back to this retinol, it's the one that my skin tolerates best, and I always look like I had a good night's sleep when I wake up after using it. Love the smell, and that you can level your way up.
