Introduction: Melasma is a skin disorder characterized by acquired hyperpigmented macules,especially in the face,and more often affects women. Its incidence is unknown.Several treatment modalities are available to control the disorder.The MASI is a useful measure in the clinical evaluation of melasma,and MELASQoL is a tool to objectively evaluate the impact on patient''''''''s quality of life.
Objective:To evaluate the effectiveness of lactic acid peeling in patients with melasma,using MASI
and MELASQoL.
Methods: 33 patients,predominantly of phototype IV,were treated with 85% lactic acid peeling (hydroalcoholic solution,pH = 3.5).Clinical results and patients''''''''quality of life were evaluated using the Melasma Area and Severity Index - MELASQoL and the Melasma Quality of Life scale,respectively,before and after treatment.
Results: A significant reduction in both indices was verified after treatment,with an average decrease of seven points in the Severity Index.No correlation was observed between the changes in the two measures,meaning that clinical improvement did not always correspond with the patients''''''''expectations regarding the treatment.
Conclusions: Lactic acid peeling is an effective,safe treatment method for melasma.
