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.

La Roche-Posay Mela B3 Dark Spot Serum With Melasyl+Niacinamide 32 ingredients
Haven't noticed any difference in my acne scars so far as all it did was induce purging (has pro-retinol in the ingredients). Been using it for like a month and not noticing any results so far, I've noticed more results after using my Caudalie serum for a week.
i am more than impressed. la roche-posay has truly outdone themselves with melasyl. this serum is an incredible product that quickly and efficiently does its job with minimal irritation. no complaints. i do feel as though it is important to note that when i started using this i had already been using retinol for 2+ months which may have affected my initial reaction to the pro-retinol ingredients Show more
