Niacinamide has emerged as an all-star ingredient due to its many benefits.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

i’ve been using this product everyday for a month and it works wonders. it has pretty much cleared almost all of my hyperpigmentation around my mouth. however my dark spots are fading much slower but still fading faster than when i’d any other dark spot correcting serum. i’m also using it on my under eyes but it seems like it is not working on that area
i would 100% recommend this product. but Show more
