I've tried several products claiming to shrink pores, this is the only one that's worked.
Lovely texture, skin feels really nourished.

Disappointed
Ever since using this product I have no end of white heads appearing on my chin - I’ve had to stop using it as it is doing more harm than good to my skin. Shame after spending the amount I did on it.

A lot of money for no noticeable improvements
[This review was collected as part of a promotion.] Does not do what it says on the tin. This is just a money making product.

Makes skin look healthier
[This review was collected as part of a promotion.] Another new product from Medik8. I have only used Niacinamide Peptides a few times as I am trying to finish my bottle of liquid peptides advanced which I love. When I have used it, I thought my skin looked healthier, hydrated and smoother when I applied make-up. I do suffer with a little redness and I think this was calmed slightly.

Great product
[This review was collected as part of a promotion.] Great product. Used this along side press and clear for a few months now and I’ve noticed a big change in my skin. My skin is smoother with less visible pores.
Nice lightweight formula and applies nicely.

Effective serum
[This review was collected as part of a promotion.] I've been very impressed with this serum. I noticed an improvement very quickly - my areas of redness and inflammation are calmer and my skin seems clearer. I've taken one star off because I would have liked more serum in the bottle - I seemed to use it up quickly.

Loved it
[This review was collected as part of a promotion.] I was quite surprised at how clear this made my skin and actually seemed to visibly reduce my pore size after one bottle. It felt lovely on my skin. Will definitely be repurchasing
