Melasma is a commonly acquired pigmentary disorder characterized by symmetric hyperpigmentation appearing as brown macules and patches on sun-exposed areas of the face and neck. The precise mechanism of melasma remains unknown; however, melasma is associated with some factors, such as genetic susceptibility, ultraviolet (UV) light exposure, pregnancy, sex hormones, contraceptive pills, cosmetics, phototoxic drugs and inflammatory processes. [1][2][3] Melasma significantly affects patients' appearance and quality of life. 4 Although various therapeutic modalities have been attempted to treat melisma, including laser ablation, chemical peeling and depigmenting agents used to lighten melasma to some degree, no universally effective procedure or agent guarantees satisfactory results. 2,3 However, clinicians and patients are especially deeply concerned of the post-inflammatory hyperpigmentation caused by laser. 5
