Brief summary
Melasma relapse is almost common after discontinuation of conventional treatment. Recent studies have suggested that photoaging dermis is main pathomechanism of melasma emphasizing stromal targeting therapy. Therefore, we investigated maintenance effect of microneedle radiofrequency (RF) for melasma treatment.
