Best retinol ever

5 stars out of a maximum of 5

I started using the number 10 after a couple of tubes of the 6, I was a bit worried just in case it was too strong but I have using it without a problem for the last three months. I use it every other night and my skin loves it, it looks and feels healthy and soft.

Brill - make sure to build tolerance

5 stars out of a maximum of 5

I’ve had numerous retinal over the years and slowly built my tolerance so this is perfect for me now, as long as I don’t use it too many nights in a row and maintain a good balance of ‘hydration’ nights to give my skin a break.

Essential

5 stars out of a maximum of 5

Cannot live without, lasts 3-4 months. Has absolutely changed my skin and reduced/stopped breakouts including over my neck and chest. I use in conjunction with their vitamin c ferulic acid (during the day) and I could not recommend more.

The best.

5 stars out of a maximum of 5

The best retinal out there for me, skin has improved so much, fine lines are nearly non existent. Started with the weakest one and have gradually moved up and I will never use another brand.

Amazing product

5 stars out of a maximum of 5

I’ve used the entire Medik8 retinal range but recently decided to buy this product since it felt like my skin had gotten used to retinal 6. I just say it feels like my skin really enjoys this product and felt like after a few uses I saw an immediate difference in my skin.
