7 min read Indian Journal of Dermatology (2023) · 380 subjects · 16-week RCT

Why tranexamic acid wins for Indian skin

Tranexamic acid blocks the interaction between keratinocytes and melanocytes without the ochronosis risk that accompanies prolonged hydroquinone use. In the 16-week RCT, TA at 3% achieved 87% of the MASI reduction seen with HQ at 4%, with 3× lower incidence of PIH.

Practical protocol for South Asian melasma

TA is ideally used twice daily with mandatory SPF 50+ in the AM. Combining with a retinoid (adapalene 0.1% PM) accelerates keratinocyte turnover and enhances depigmentation. Results are visible at 8 weeks; full effect at 16–20 weeks.
