The Management of Melasma on Skin Types V and VI Using Light Emitting Diode Treatment.

OBJECTIVE This study investigated light emitting diode (LED) treatment for patients with melasma on darker skin types. BACKGROUND Melasma is a common disfiguring skin condition in women which is difficult to treat and is refractory. The cause of melasma remains unclear. METHODS In this study, 60 female participants aged between 25 and 60 years, who presented with melasma, were enrolled (n = 39.85). They were purposely assigned to two groups according to their skin types. Both groups received a total of 36 LED light treatments over a period of 9 months. RESULTS Both subjective and objective results indicated a significant improvement of melasma. Statistical analyses revealed significant improvements in both groups. CONCLUSIONS The results of this study suggest that LED is effective in managing melasma. These results will provide a basis for future therapeutic use of phototherapy to improve melasma.
