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 compound has demonstrated remarkable efficacy in treating various hyperpigmentation disorders, including melasma, post-inflammatory hyperpigmentation, and sun spots.

Tranexamic acid functions by inhibiting melanin synthesis through multiple mechanisms. It interferes with the interaction between melanocytes and keratinocytes, reducing melanin production and transfer. Additionally, it inhibits plasmin, an enzyme that plays a role in melanin formation and inflammation.

Typically used in concentrations ranging from 2% to 5% in topical formulations, tranexamic acid can be found in serums, creams, and lotions. It is generally well-tolerated by most skin types and can be combined with other brightening agents like vitamin C, niacinamide, or alpha-arbutin for enhanced results.

Clinical studies have shown that tranexamic acid can significantly improve skin tone and reduce the appearance of dark spots within 8-12 weeks of consistent use. Its anti-inflammatory properties also make it beneficial for treating redness and sensitive skin conditions.
