    Doesn't irritate my sensitive skin!

    My sensitive skin doesn't typically like Niacinamide. I usually have to use a very low strength. But the INKEY Lists 10% Niacinamide serum doesn't cause my skin to react! I was so surprised! And of course it works wondergully!! Absorbs quickly, does its job with no irritation, sign me up!!!
