Tranexamic Acid

INCI: Tranexamic Acid. Tranexamic Acid (TXA) is a synthetic derivative of the amino acid lysine, used in cosmetic formulation as a brightening active for the evenness of skin tone and the appearance of dark marks and sun spots. It works by interrupting melanin synthesis, and is non-exfoliating, which makes it a gentle option suited to all skin types.
