Ingredient
Tranexamic Acid (TXA)
A versatile brightening ingredient that fades dark spots and reduces the redness triggered by inflammation — particularly effective for melasma and inflammation-linked pigmentation. Look for 2–5%, with 3–4% being the range where clinical results are most consistent; visible improvement typically appears within 4–8 weeks. Frequently paired with niacinamide in K-beauty for a synergistic effect.
Ingredient
Suitable for
Melasma and stubborn hyperpigmentation — especially effective when dark spots are linked to inflammation or redness, where many other brighteners fall short.
Also suitable for sensitive skin, oily skin, dry skin and redness-prone skin.

Combinations that work
- NiacinamideBrightening
They interrupt pigment at two different points — tranexamic acid quiets the signal that tells melanocytes to produce, niacinamide blocks the transfer of finished pigment to surface cells. Studied together for melasma and post-acne marks.
- Vitamin CBrightening
Vitamin C interrupts pigment as it is being formed; tranexamic acid quiets the inflammatory signal that starts the process. Useful for pigmentation that keeps returning after it fades.
- Azelaic AcidBrightening
Two different points in the same pathway: azelaic acid inhibits tyrosinase directly, tranexamic acid interrupts the signal that activates the melanocyte. Studied together for melasma and stubborn post-acne marks.
Combinations to avoid
Tranexamic Acid (TXA) has no documented conflicts with anything else in this library. It can sit anywhere in a routine.
