good molecules niacinamide brightening toner

Really interested with that toner as well! Niacinamide is an active of vitamin B3, but it doesn’t cause purging. Niacinamide is pretty much well tolerated by all skin types. If you experience breakouts, it may be because your skin is having a bad reaction to it or another ingredient in the product.
