Medik8 Niacinimide Peptides
[This review was collected as part of a promotion.] I’ve been using Medik8 Niacinamide Peptides and it’s become one of my favourite lightweight serums. The texture is really light and absorbs quickly without leaving any sticky feeling, which makes it perfect for both morning and evening routines.
After a few weeks of using it consistently, my skin looked calmer, smoother, and more balanced overall. I especially noticed an improvement in redness, skin texture, and the appearance of pores around my T-zone. It layers beautifully with other skincare products and doesn’t feel heavy or greasy, even under makeup.
The combination of niacinamide and peptides makes it great for supporting the skin barrier while also helping the skin look healthier and more even over time. It gives that fresh, healthy-skin look without irritation.
I’d recommend it to anyone looking for a gentle but effective serum that improves overall skin condition while still feeling lightweight and comfortable on the skin. I’ve actually just purchased my second bottle, which says a lot about how much I’ve been enjoying it.

Amazing product
[This review was collected as part of a promotion.] I use Niacinamide peptides only at night and I am very satisfied. My skin is softer, I have no pimples, my pores are clean and smaller. It also has a lifting effect.

Good as usual
[This review was collected as part of a promotion.] I read about this in a Sunday Times review and decided to try it.
First impressions are good, it sinks into the skin easily and compliments my Medik8 routine.

Great product, packaging needs improving
[This review was collected as part of a promotion.] Really like the product, my skin looks smoother. But the packaging isn’t great, I’m finding the pump gets stuck quite easily/often and then product is wasted spurting out of it.
