How to choose niacinamide skincare

What does niacinamide do?

Niacinamide supports the skin barrier and can improve the appearance of uneven tone, visible pores and excess shine. Korean formulas often combine it with hydrating or soothing ingredients for a more balanced routine.

Which strength should you choose?

Higher percentages are not automatically better. New or sensitive skin may prefer a lower-to-moderate strength, while concentrated formulas are better introduced gradually by experienced users.

Choose the right format

  • Serum: A targeted step applied before moisturiser.
  • Moisturiser: An easy way to include niacinamide in a shorter routine.
  • Mask: An occasional hydrating step rather than a replacement for consistent daily care.

How to use niacinamide

  1. Apply after cleansing and watery toner.
  2. Follow with moisturiser.
  3. Use SPF every morning, especially when addressing uneven-looking tone.
