Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Glow! [This review was collected as part of a promotion.] Really enjoying this serum. I find it very effective at clearing breakouts and preventing new ones! Definitely helped with smoothing skin texture, will repurchase!

Rated 4 out of 5 by from Good Product Decent product, has reduced the visibility of stubborn blemishes. Still struggling with dullness and uneven skintone - only been using for 3 weeks. Hoping to see more results over time. I have very sensitive skin.

Rated 5 out of 5 by from Honestly I’ve tried so many [This review was collected as part of a promotion.] Honestly I’ve tried so many different things to minimise the look of pores and blackheads and nothing has worked. Until this! It has reduced the overall appearance my face looks so much clearer and I now go places with minimal to no make up on. I paired this product with the press and glow (blue version) and I cannot recommend enough!! You won’t be disappointed at all!

Rated 5 out of 5 by from Amazing product even for sensitive skin [This review was collected as part of a promotion.] I have been using clarity peptides for years and didn’t think there could be a better product. Until now. Niacinamide peptides keeps my skin even clearer, smoother and hydrating. I have sensitive skin and no issues with this product. Highly recommend.

Rated 5 out of 5 by from A simply lovely product! I have very sensitive, acne-prone skin and have been looking for a product to help improve my blocked pores/skin texture. I can’t say 100% if it’s working BUT I haven’t had any breakouts from the product, it feels incredible on my skin, smells lovely and makes me skin look and feel much fresher. Hopefully, over time, it can help my skin texture more visibly, but I’m very impressed with the quality and the fact it hasn’t negatively triggered my skin!

Rated 5 out of 5 by from Great [This review was collected as part of a promotion.] I have just started to use this and already I am seeing an improvement in my skin. Can’t wait to see what it looks like after I have been using it for longer.
