Holy Grail

5 stars out of a maximum of 5

I really rate Medik8 products. Excellent products at a decent price point and superior to more expensive products. This smooths and evens out the skin without causing irritation

Too expensive

3 stars out of a maximum of 5

I liked the ingredients of this product and thought it would help me with my skin texture but it did absolutely nothing! I used up the whole tube and saw no benefit. Waste of money.

Great product

5 stars out of a maximum of 5

I haven't used any retinol before so after some reviews decided to with no 3. Started once a week with a moisturise before and after as I have a dry skin, after a month I increased it to to 2-3 times and my skin looks like a glass! Love how it transformed my face.

Amazing

4 stars out of a maximum of 5

Amazing retinol once you have become more used to the less harsh ones. Really does transform your complexion and make fine lines less noticeable.

noticeable improvement

5 stars out of a maximum of 5

I've been using it for only three weeks now, but I can notice such great improvement -- unlike other retinol I've used in the past. I can't wait to graduate to the stronger one!

The Best!

5 stars out of a maximum of 5

Been using this serum now for a good year. Used 3 first then worked my way up to 6. A little goes a long way and this tube will last me months. My skin looks clearer, more even and less blotchy. At 39 years old , my skin is the best it’s ever looked. Will always repurchase this.
