Can you use niacinamide and vitamin C together?
Yes. Niacinamide and vitamin C are fine together. The idea that they cancel each other out comes from old tests that don’t match how products are made today.
Fine together
These don’t clash. Layer the thinner one first.
Layer them in the same routine, thinnest texture first. In the morning, finish with sunscreen.
How to use them together
Apply vitamin C first in the morning, then niacinamide, then moisturizer and sunscreen.
Plenty of serums already combine the two. If a pure vitamin C serum stings when layered, use them at different times of day.
