Effect of Intense Pulsed Light versus Intradermal Tranexamic Acid for the Management of Melasma.

Abstract

To compare the effectiveness of intense pulsed light (IPL) and intradermal tranexamic acid (TXA) in treating melasma. A cross-sectional analytical study. Place and Duration of the Study: Department of Dermatology, Dow International Medical College, Dow University Hospital, Karachi, Pakistan, from 15th January to 15th July 2023. A total of 62 patients with melasma, aged 20-50 years, were divided into two groups. Group A (32 patients) received IPL (560 nm filter was used) treatment, and Group B (30 patients) received intradermal TXA. Each group underwent four treatment sessions with varying intervals. Melasma area and severity index (MASI) scores were used to compare the effects of treatment. After a 3-month treatment period, both groups showed reduced mMASI scores compared to baseline with a significant initial difference between Group A (8.6 ± 4.2) and Group B (5.4 ± 2.7, p <0.001). However, post-treatment, there was no significant difference in mMASI scores (Group A: 3.8 ± 2.6; Group B: 3.2 ± 2.0, p = 0.29). IPL treatment (Group A) demonstrated a significant reduction in mMASI scores (57.1 ± 19.7) compared to intradermal TXA treatment (Group B, 42.2 ± 18.8, p = 0.0034). Both IPL and intradermal TXA treatments effectively reduced melasma, with IPL exhibiting superior results. However, post-treatment outcomes converged, emphasising the need for personalised approaches considering the unique characteristics of South East Asian skin.
