Tranexamic acid has become a go-to for stubborn discoloration that other brighteners struggle with — including melasma.
What it does
Tranexamic acid interrupts the pathway that leads to excess pigment, helping fade dark spots, post-acne marks, and melasma over time. It’s especially valued for stubborn, recurring discoloration.
How it fits with other brighteners
It works alongside other hyperpigmentation ingredients rather than competing with them:
- Vitamin C (morning antioxidant + brightener)
- Niacinamide (interrupts pigment transfer)
- Azelaic acid and alpha arbutin
The catch
As with all pigmentation treatments, daily sunscreen is non-negotiable — UV undoes the work faster than any serum can fade it. Expect weeks to months for results, and see a dermatologist for deeper or persistent melasma. For the full strategy, read fading dark spots: what actually works.
