Magnesium Ascorbyl Phosphate (MAP) +
Niacinamide (
Vitamin B3 ) is in the same formula. Can it be mixed together? because I've read that
วิตามินซี should not contain
B3 is in the formula, so I'm not sure. But there are many brands of serums that contain derivatives.
วิตามินซี Map and
B3 is mixed in the same formula. So I want to know to know if this serum can be mixed in the same formula or not. and have any side effects? Thank you.
