Do both Niacin And Niacinamide  interact negitivly with vitamin C If combined in creams and serums??

Thank you for your time, I appreciate your opinions.


The question of mixing these creams together and having the side effect of weakening both is not true with niacinamide and Vit C. They are both good products and can be mixed together if desired. I will say that when mixed, they turn to a yellow color but they still work well. Mixing niacin with Vit C can cause some redness, a rash appearance, and flushing so most people avoid it.
