Many routines combine a niacinamide serum with a niacinamide moisturizer or cleanser. Introduce new products one at a time so you can track how your skin responds.

Niacinamide is used across formulas intended for different skin types, though individual tolerance varies by product and person. Always check the specific product listing and patch test before full use.

This page covers all product formats containing niacinamide. The Niacinamide Serum collection covers the serum step specifically.
