Skin Brightening Agent

Tranexamic Acid

Tranexamic acid is a synthetic amino acid derivative that works by inhibiting plasminogen activator, thereby reducing the production of arachidonic acid and UV-induced pigmentation signals that stimulate melanin synthesis. Originally developed as a haemostatic drug, it has been extensively studied as a topical brightening ingredient effective against melasma and other forms of hyperpigmentation. It works through a different mechanism than many other brighteners, making it a useful option when combined with or alternating with ingredients like niacinamide or kojic acid.
