Rated 5 out of 5 by from Great Addition to My Skincare Routine [This review was collected as part of a promotion.] I’ve been using Medik8 Niacinamide Peptides and I’m really happy with it. It feels lovely and lightweight on my skin, absorbs quickly, and fits perfectly into my skincare routine. My skin feels smoother, more balanced and generally looks healthier since I started using it. It also works really well with my other skincare products without feeling heavy or sticky. So far, I’m very pleased with the results and would definitely recommend it. It’s a product I’m happy to continue using and repurchase.

Rated 5 out of 5 by from Great product for oily skin I really needed a product that addressed my oily skin, but I didn't want to add another serum on top of my peptides. This is perfect. I'm six weeks in and my complexion is much more mattfiied and my fine lines are even finer. The consistency is very light and absorbs almost instantly. Huge fan. Haven't found any men's skincare product that beats this.
