Modified Jessner's Solution Combined With Trichloroacetic Acid 20% Versus Glycolic Acid 70% Combined With Trichloroacetic Acid 20% in the Treatment of Melasma

Background Melasma is an acquired challenging pigmentary skin problem, which commonly affects the face. A wide range of therapeutic modalities is available, yet none is satisfactory. Objective To compare efficacy and safety of trichloroacetic acid (TCA) 20% peeling with either modified Jessner's solution (MJs) or with glycolic acid (GA) 70% peeling in the treatment of melasma. Patients and methods Thirty adult Egyptian women with melasma were recruited in the study. After cleansing the face, MJs was applied on one side of the face and GA 70% on the other side. Then, TCA 20% was applied in one uniform coat on both sides of the face. Assessment of the clinical response was guided by calculating the melasma area, severity index (MASI), modified MASI, and hemi-MASI scores before and after the end of treatment. Results Both combinations showed significant reduction in MASI, modified MASI, and hemi-MASI scores (p value = .000, for each). Moreover, the hemi-MASI score after MJs and TCA20% showed a significant decrease compared with GA70% and TCA20% (p value = .013). Conclusion Both modalities are successful, safe options for treating melasma. Moreover, combining MJs with TCA 20% is more efficacious.
