Tranexamic acid is a powerful brightening ingredient that helps reduce the appearance of hyperpigmentation, melasma and post-inflammatory dark spots. Originally developed for medical use, it has become a popular skincare ingredient because of its ability to interrupt the processes that lead to excess melanin production. Unlike exfoliating acids, tranexamic acid does not remove dead skin cells but instead works to improve skin clarity while helping to calm inflammation. It is generally well tolerated by most skin types, including sensitive skin.
In K-Beauty, tranexamic acid is commonly found in serums, ampoules and creams formulated to target pigmentation and improve skin radiance. Korean skincare values tranexamic acid for its gentle yet effective approach to brightening the skin without compromising the skin barrier. It is often paired with ingredients such as niacinamide, alpha arbutin, vitamin C and hyaluronic acid to enhance brightening results while maintaining hydration.
