A Retrospective Study of the Management of Chinese Melasma Patients Using a 1927 Nm Fractional Thulium Fiber Laser

Background: A new fractional photothermolysis device is used in our retrospective study to treat melasma in Chinese patients.

Objectives: To evaluate the efficacy and safety of the 1927 nm fractional thulium fiber laser in the treatment of melasma in Chinese patients.

Methods: Eleven melasma patients who received treatment between November 2009 and May 2010 were included. Photographic images at baseline and follow-up were assessed for clinical efficacy and complications by two independent and blinded physicians. Questionnaires were also completed by patients.

Results: Significant MASI improvements were seen at 1 week, 1 month and 2 months, but not at 3 months. Patients' degree of satisfaction was high. Significant improvement in skin texture and pore size was seen for up to 2 months and improvement in wrinkles for up to a month. There was no change in skin laxity. Main adverse effects seen were erythema, edema, and crusting in the early days. One patient developed PIH.

Conclusion: The novel 1927 nm fractional thulium fiber laser is safe and effective in the management of melasma in Chinese patients for up to 2 months. It is also useful in photo-rejuvenation. Complications were limited to erythema and edema in the early days, and transient PIH.
