luuusch02 review for Niacinamide
Love it! It has helped me to control the oily areas of my face. I normally use it before my acne treatment and the hydrating and soothing ingredients in this serum reduced the irritation a lot.
I have read that higher concentration of niacinamide than 5% are unnecessary. Also 10% can be irritating to some people so be careful.
i haven’t had any issues with irritation probably because my skin is so oily
