Applied to the skin it interferes with the plasminogen-plasmin pathway in keratinocytes, dampening UV-induced prostaglandin and arachidonic-acid signaling to melanocytes and thereby reducing melanocyte tyrosinase activity and melanin production without decreasing the number of melanocytes. It is formulated as a serum or cream, typically at concentrations of 2-5%, for melasma and other facial dyschromia. ## Its role in longevity In randomized controlled trials and multiple meta-analyses, topical tranexamic acid significantly lowers melasma severity scores (MASI/mMASI and melanin index) and performs comparably to the long-standing standard agent hydroquinone, frequently with fewer irritant side effects; combining it with microneedling or laser-assisted delivery can add further benefit. Honest limitations: many trials are small, short (typically 8-12 weeks) and heterogeneous, melasma tends to relapse after treatment stops, and pooled analyses indicate oral TXA is more potent than the topical form, though the oral route carries clotting-risk contraindications that minimally absorbed topical use largely avoids. The evidence is specific to melasma and hyperpigmentation; broader anti-aging claims are extrapolation. This evidence concerns the compound tranexamic acid and its mechanism and formulations, not this specific commercial serum product. ## Evidence grade: Moderate evidence - **What the grade means:** Curated grade based on the human and mechanistic evidence for this compound. - **Dose used in studies:** 2-5% topical cream or serum, typically for 8-12 weeks - **What this grade does not say:** Randomized trials and meta-analyses support topical tranexamic acid for melasma, roughly comparable to hydroquinone with fewer side effects. Trials are short and heterogeneous, melasma often relapses after stopping, and benefits beyond pigmentation (general anti-aging claims) are extrapolation. ## In the news - **The 9 best tranexamic acid serums to fade dark spots, according to derms** — NBC News 2026 [Read it](https://www.nbcnews.com/select/shopping/best-tranexamic-acid-serum-rcna146988) > Tranexamic acid is a skin care ingredient derived from the amino acid lysine that can reduce the appearance of dark spots - **Tranexamic Acid for Skin: Benefits, Safety, How to Use** — Healthline 2022 [Read it](https://www.healthline.com/health/beauty-skin-care/tranexamic-acid-for-skin) > After 12 weeks, the severity of melasma decreased by 27 percent in the group using tranexamic acid ## The research Peer-reviewed studies on the active compound.
