Acid Name: Tranexamic Acid
What It Does: Tranexamic acid is one of the most talked-about acids as of late because “it noticeably improves skin discoloration and decreases pigment production in melanocytes, the skin cells that are hyperactive in melasma pigment production,” says New York dermatologist Julie Russak, MD, who often recommends it for her patients with melasma.
What Makes It Different: “Originally used in cases of blood loss during open heart surgery, tranexamic acid is commonly used today to treat hyperpigmentation,” says Dr. Russak. “Unlike skin-bleaching hydroquinone, it is safe for long periods of use—discuss it with a board-certified dermatologist first—and can be paired with other gentle acids, antioxidants like vitamin C, and SPF.”
