It seems like every single skincare product on the market right now has Niacinamide in it. It's supposed to be amazing for fading pigmentation and evening skin tone, but honestly, every time I use a serum with a high percentage of niacinamide (like 10%), my skin breaks out in tiny bumps and gets super red. Am I allergic to it, or is 10% just too strong? Has anyone else experienced this?
