Tranexamic Acid
Description
Tranexamic acid is a synthetic derivative of the amino acid lysine that has gained significant attention in the skincare industry for its skin-brightening and anti-inflammatory properties. Originally used in medicine to control excessive bleeding, this versatile compound has demonstrated remarkable efficacy in addressing various dermatological concerns, particularly hyperpigmentation and melasma.
The ingredient works by inhibiting melanin production through multiple mechanisms. It interferes with the interaction between keratinocytes and melanocytes, reducing melanin synthesis. Additionally, tranexamic acid inhibits plasmin, an enzyme that plays a role in melanin production and inflammation.
Clinical studies have shown that topical application of tranexamic acid can effectively reduce the appearance of dark spots, even skin tone, and improve overall skin clarity. Its anti-inflammatory properties also make it beneficial for treating conditions like rosacea and post-inflammatory hyperpigmentation.
Tranexamic acid is generally well-tolerated and can be used in conjunction with other skincare actives. It's typically formulated at concentrations between 2% to 5% in over-the-counter products. For optimal results, consistent use over several weeks to months is recommended, along with proper sun protection to prevent further pigmentation issues.
