A great experience, so far!

5 stars out of a maximum of 5

I have the most sensitive acne prone skin. I was so nervous about using a retinal but after so many recommendations, and my skin worsening, I decided to give and and give this a go. I’m super pleased I did. It got to work on my acne after just one use. It smells delightful and soaks in lovely. I’ve used it twice now, just starting with once per week and then I will gradually build up. If you’re like me and you’re hesitant, give it a go, you won’t regret it!

Good beginners retinol

Good as an introduction to retinol. Medik8 is one of the best skincare brands in my opinion. All the products work well together. This retinol under the ceramide cream is a winning combination!

My new favourite!

5 stars out of a maximum of 5

I have used a retinol product of some sort for over 20 years now but recently read an article that advised Retinal was the way forward. So gave this a go. Really pleased that I did ! A lovely serum, non greasy and smells lovely and my skin is looking so good. I will be 70 this year and want to look good for as long as I can,  Definite repeat purchase .
