Efficacy and Safety of Picosecond, Neodymium-doped Yttrium Aluminum Garnet Laser Therapy Using 1,064 nm and 595 nm

Efficacy and Safety of Picosecond, Neodymium-doped Yttrium Aluminum Garnet Laser Laser Therapy Using 1,064 nm and 595 nm on Patients With Melasma: A Prospective, Multi-center, Split Face, 2% Hydroquinone Cream-controlled Clinical Trial

This is a prospective, multi-center, split-face, controlled clinical trial that aims to investigate the efficacy and safety of picosecond, neodymium-doped yttrium aluminum garnet laser laser therapy on patients with melasma, compared with 2% hydroquinone cream. The trial will be performed by two Korean institutions on 45 subjects.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Success rate of treatment according to RL*I	The success rate is determined by the change rate (%) of the relative lightness measured before the treatment (day of screening) and 1 week after the final treatment.	Baseline, 1 week after final treatment

Secondary Outcome Measures

Outcome Measure	Time Frame
Relative skin lightness using the colorimeter(RL*I)	Baseline, 1 week, 4 weeks, and 12 weeks after the final treatment
mMASI (modified Melasma Area Severity Index) evaluation	Baseline, 1 week, 4 weeks, 8 weeks, and 12 weeks after the final treatment
Subject satisfaction (5-point scale questionnaires on subject's satisfaction)	1 week and 12 weeks after the final treatment
