Tranexamic Acid

Helps to reduce hyperpigmentation and redness. Synthetic lysine analog that inhibits plasminogen activator, reducing UV-induced plasmin activity in keratinocytes. Plasmin normally stimulates melanocyte activity via arachidonic acid release; blocking it reduces melanogenesis. Also inhibits mast cell activity and angiogenesis in the dermis, reducing post-inflammatory erythema. Works through a completely different pathway than tyrosinase inhibitors, making it complementary.

Well tolerated topically. Oral form used safely for decades as antifibrinolytic drug. Topical application avoids systemic effects. No photosensitivity. Safe for all skin types including sensitive skin.

Look for products with 2-5% (topical), oral dosing varies for clinical efficacy.

Use Tranexamic Acid with AHAs (Glycolic, Lactic, etc.) carefully. Tranexamic acid is generally safe with AHAs, but combining multiple brighteners with exfoliants can irritate sensitive skin.

Tranexamic Acid can be used with Niacinamide. Tranexamic acid and niacinamide are a brightening power duo. Both fade dark spots through different mechanisms.

Tranexamic Acid can be used with Vitamin C. Tranexamic acid + vitamin C target hyperpigmentation from multiple angles. Safe to layer together for faster brightening.

Tranexamic Acid can be used with Retinoids. Tranexamic acid and retinoids are a powerful combination for hyperpigmentation. TXA blocks melanin transfer while retinoids accelerate cell turnover — they work through different pathways and are safe together in PM routines.
