kamiey review for Azelaic Acid 10% Serum with Niacinamide

I've read a lot of good review about azelaic acid, so decide to try this one cuz I've been using few product from CDB, it's doesn't irritate my skin, I use it 2 times a day, as I can't use retinol due to pregnancy, this is a safe and great alternative to tackle the incoming acne/melasma/pigmentation .
