Watch out
Brightening ingredients only hold up with daily sunscreen — without it, UV keeps re-triggering the discoloration. Results are gradual (think weeks to months). Melasma and persistent pigmentation can need professional care — see a board-certified dermatologist.
FAQ
How long does tranexamic acid take to work?
Brightening is slow — usually several weeks to a few months of consistent use, and only if you wear sunscreen daily. It is a marathon, not a quick fix.
Tranexamic acid vs vitamin C vs niacinamide for dark spots?
They work differently and often pair well. Vitamin C is an antioxidant brightener, niacinamide supports tone and barrier, and tranexamic acid targets the look of stubborn discoloration. Many good "brightening" formulas combine them.
Is tranexamic acid safe for sensitive skin?
It is generally one of the gentler brightening options and is usually well tolerated. Patch-test as you would with any new active, and if you have melasma, loop in a board-certified dermatologist.

The honest note: ingredients help — they don't treat medical conditions. For persistent skin issues, a board-certified dermatologist beats any product swap.
