Great
[This review was collected as part of a promotion.] I really liked this serum, it felt light and it’s a great active component. As I got a tester, I’ll be looking to buy a full-size bottle later.

Effective
[This review was collected as part of a promotion.] I bought this to help clear up my teenage daughter's breakouts and it does seem to be working to make her skin look clearer, when she can be bothered to use it!

Good product
[This review was collected as part of a promotion.] The texture of the serum is lovely, glides on the skin and dries really fast. The only reason I put 4 stars is the pump, really hard to work around and the products extraction is a bit difficult, resulting sometimes the product being splashed around

Not for me. . . . . . .
[This review was collected as part of a promotion.] I have sensitive combination skin with a couple of severe red patches. As I was already using a couple of products from this range I decided to try this serum as I thought it would help with the condition and appearance of my skin and was described as being gentle. After using as directed for just under a week I developed additional red patches on my neck and a fungal skin infection which I am prone to getting. I stopped using it and tried again once my skin had calmed down this time only using the serum every other day but the same thing happened. It is disappointing as the effect the serum creates is great but it obviously does not agree with me.

Really great product
[This review was collected as part of a promotion.] I love it. I use it at night before the retinal and it really makes a difference. My skin is soft and clean and I like the texture, very light and it absorbs great. I tried it just to see and it is going to become a must in my routine.

It works!
[This review was collected as part of a promotion.] I bought this for my son as he gets spots but I've ended up keeping it for myself. I get the odd hormonal spot and it clears up so quickly - overnight plus it's a lovely soft feel on skin and you can feel it soothing your skin.
