Can you mix niacinamide with direct acids like AHA BHA?
Posted by Sandy Hippo on
Niacinamide is an active form of Vitamin B3 found in animals and plants. Niacinamide gives optimum results at pH of 5-6.
It's fine to layer niacinamide with other serums in your skincare regimen because your skin absorbs the niacinamide serum instantly. However we do not recommend mixing niacinamide into a direct acid solution.
Niacinamide can hydrolyze and form nicotinic acid at higher or lower PH, which can result in skin irritation.
