Rated 3 out of 5 by from Unclear results Not sure about this yet, have been using for 2 weeks and there’s not much results but no damage down at least

Rated 1 out of 5 by from Had high expectations.. I had high hopes for this serum, but unfortunately it didn’t suit my combination skin. Although it feels lightweight and absorbs well, I consistently noticed more redness and a few small pimples the next morning. My skin is usually clear, and I wasn’t layering it with other actives. Interestingly, vitamin C works much better for me. Sadly, this niacinamide formula just wasn’t a match.

Rated 5 out of 5 by from 10/10 The best serum I’ve ever used, I have combination acne prone skin so I struggle to find the right products but with this serum I seen results in just a few days and I will never go back! It’s on the pricier side but worth every penny, it gets rid of hyperpigmentation really quick as well as leaving skin soft and glowy, I’ve noticed less breakouts also

Rated 4 out of 5 by from Medik8 Niacinamide Peptides As a Medik8 fan, I ordered the serum Niacinamide Peptides , Milky tends to be a lightweight liquid, elegant light blue container, but be careful, it squirts everywhere, so it is recommended to apply directly to the face, absorbs well, it is difficult to assess the degree of effectiveness from the first week, I estimate that it is as effective as other Medik8 products
