Updated August 18, 2026
Niacinamide and tranexamic acid target discoloration; slow results, some irritation.
What the community says
A serum with 4% niacinamide and 3% tranexamic acid for fading pigmentation and brightening dull skin. Favored for mild irritation risk and accepted by sensitive skin users. The trade-off is that it works slowly and may cause redness in sensitive skin types.
