Tranexamic acid, originally used to stop bleeding in surgery, has shown effectiveness in treating several skin issues including melasma, acne, rosacea, and post-inflammatory hyperpigmentation. It works by reducing inflammation, blocking new blood vessel formation, and slowing melanin production. The ingredient can be used topically, orally, or injected, and often works better when combined with other treatments.

This was a review article that examined existing research on tranexamic acid's use in dermatology across multiple skin conditions and application methods.
