Niacinamide Peptides
[This review was collected as part of a promotion.] Thanks to Medik 8 I was able to try a sample of the new Niacinamide Peptides . It sinks into the skin easily with no tacky feeling . It is non Comedogenic so will not break me out as I have combination skin. Hopefully overtime it will reduce blemishes & help prevent future breakouts while balancing congestion-prone skin & the look of pores . I will try the full size product thanks 🙏

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.
