Question: Do not mix vitamin C and vitamin B3 in the same bottle.

Note that vitamin C and vitamin B3 should not be mixed in the same bottle.

1 If separate bottles are vitamin C and B3 , each bottle should be applied How far apart do you have to be to have good performance?

2. Or should not be applied overlapping each other?




Thank you.

Inquire. 1. It's a sebderm. The face is tight. It's very dry and red. When there is a product, cream or serum or any substance that can help? 2. What kind of acne scars can help to get rid of dark spots? Thank you.
