Tranexamic Acid

Tranexamic acid is a synthetic derivative of the amino acid lysine. It is primarily used in skincare to address hyperpigmentation, including melasma and post-inflammatory hyperpigmentation. It works by inhibiting a pathway in the skin that leads to melanin production and can also help calm skin.
