It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
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.

This is too expensive for a 30ml. You can get a pure niacinamide serum from Good Molecules at a sustainable price. I don’t feel like it’s doing anything to my skin.
Naturium Niacinamide Serum 12% Plus Zinc 2% 16 ingredients
I really do love this product. The mix of niacinamide and zinc underneath my sunscreen make me feel super protected during the day. Especially since I cannot tolerate Vitamin C as my antioxidant. And this pairs super well with Paula's Choice BHA Gel Exfoliant on days where I'm having acne breakouts. I <3 it here!
It has helped my skins redness go way down after a couple uses. But after a while my redness and acne kind of came back worse..
