Melasma is a recurrent skin disorder characterized by hyperpigmentation due to melanocytic dysfunc-tion.Melasma can have a negative psychological impact on patients,which significantly affects their self-esteem.Melasma treatments that have temporary effects leave patients with unsatisfactory results.Usinga prescription depigmenting agent in combination with a retinoid often will improve melasma symp-toms.In addition,a maintenance regimen should be used to prevent recurrence of lesions.Althoughmany maintenance therapies are available,proper sunscreen protection is vital to prevent lesion recur-rence.When selecting a sunscreen,it is important to choose one that contains both UVA and UVB filters.Frequent application of sunscreen to exposed areas is necessary during intense sun exposure.Additionally,patients need to be educated about the hazards of both UVA and UVB exposure.
