How Tranexamic Acid May Transform
Your Skin Discoloration
Tranexamic acid is typically a medication to promote blood clotting for those with heavy menstrual periods or bleeding disorders; however, when applied to your skin, it can help with some forms of skin discoloration as well. According to dermatologist Anna Guanche, MD, it is because "tranexamic acid interferes with melanin production."
The acid has also been shown by various studies to improve skin discoloration from other sources, including acne and sun damage. “Tranexamic acid has shown promising evidence as a plasmin inhibitor and therefore an effective treatment for UV induced discoloration, dark spots, and redness," revealed cosmetic chemist Krupa Koestline.
However, since the acid interferes with the production of melanin and is a skin-lightening ingredient, it may not be the right skincare ingredient for everyone to try. If you have a medical condition that already affects your body's production of melanin, for example, consult a dermatologist before incorporating it into your skincare routine.
