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

Abstract

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.
