Introduction: Treatment of melasma is challenging. Topical TA has shown promising results as an adjuvant, when combined with microneedling or QS Nd:YAG laser. The efficacy of both combinations has been demonstrated but the efficacy between these two combinations has never been compared.
Aim and objectives: To compare the efficacy and side effects of microneedling and QS Nd:YAG laser when combined with topical 3% TA gel.
Materials and methods: 60 patients were randomized into 2 groups. Group A received Nd:YAG laser sessions monthly with daily 3% TA gel while Group B underwent microneedling monthly with daily 3% TA gel. A total of 5 sessions were given with follow-up after 2 months. Evaluation using modified Melasma Area and Severity Index (mMASI), Patient satisfaction score, and photography was done at baseline, 3rd session, 5th session, and final follow-up.
Results: Mean fall in mMASI at follow-up in Group A was 5.12 ± 2.66 to 2.33 ± 1.33 and Group B was 4.60 ± 2.38 to 1.88 ± 1.08 (p < 0.001). Patient satisfaction score was not significantly different. Side effects of both interventions included erythema, pain, and burning sensation.
Conclusion: Our study shows equal efficacy of microneedling and QS Nd:YAG laser when combined with topical 3% TA gel in treating melasma without serious side effects. Microneedling has more downtime and maybe less preferable as a lunchtime procedure.
