Combination of fractional QSRL and IPL for melasma treatment in Chinese population

BACKGROUND: Melasma is the most common and distressing pigmentary disorder presenting to dermatology clinics. Various treatment protocols for melasma have been suggested in the previous literature and applied in various clinical settings. However, no satisfactory therapy has been widely accepted. OBJECTIVE: To evaluate the efficiency and safety of a combination treatment with fractional Q-switched ruby laser (QSRL) and intense pulsed light (IPL) for melasma in Chinese population. METHODS: Fifty-three Chinese melasma patients were enrolled in this study. Each patient underwent 2 courses of treatments at 2-week interval. One course was composed of 3 successive sessions of 694-nm fractional QSRL at intervals of two weeks followed by one IPL. The efficacy was evaluated by non-invasive measurements and subjective assessments. The adverse effects were recorded. RESULTS: Mean melanin index (MI) and erythema index (EI) significantly decreased from 216.1 and 381.8 pre-treatment to 167.8 and 310.3 post-treatment, respectively. Mean melasma area and severity index (MASI) decreased dramatically from 14.66 before treatment to 5.70 after the final treatment. These values remained at low levels at 3-month follow-up. The percentage of patients who achieved moderate or significant improvements was 73.6%. Adverse effects of QSRL and IPL were minimal. CONCLUSION: The combination treatment of fractional QSRL and IPL would be a promising modality for managing melasma in Chinese patients.
