Niacinamide and AHAs and BHAs
Niacinamide used with AHAs and BHAs together have no effect and can actually cause redness. Because niacinamide has a pH of around 5-7, it can actually raise the lower pH of the acids, which is around 3-4, and cancel out its properties. Used separately, both ingredients can help skin texture, acne, and signs of aging, so we encourage you to still use them.
