Patch test on a small area before first use. Avoid the eye area. Stop use if irritation occurs. COSRX recommends not layering this with a vitamin C serum at the same time; use them at different times of day. Wear sunscreen daily.

Can I use it with vitamin C?

COSRX suggests using them at different times, for example vitamin C in the morning and niacinamide at night.

Is 15% niacinamide too strong?

It is a concentrated formula. If your skin is sensitive, start once a day and build up.
