Tranexamic Acid
Tranexamic Acid — a synthetic derivative of the amino acid lysine used topically to help fade discoloration and even skin tone. It is thought to interrupt the interaction between skin cells and pigment-producing melanocytes, making it a popular choice for melasma and post-inflammatory hyperpigmentation.
Key points
- Tranexamic acid was originally developed as an oral medication to reduce bleeding and is now widely used topically in skincare.
- It helps limit excess pigment production by interfering with signaling between keratinocytes and melanocytes.
- It is frequently studied and used for melasma, sun-induced spots, and post-inflammatory hyperpigmentation.
- Topical tranexamic acid pairs well with ingredients like niacinamide, vitamin C, and sunscreen for tone-evening routines.
Frequently asked
What does tranexamic acid do for the skin?
