Melasma is a skin disorder caused by dysfunction in melanogenesis, and this study aimed to investigate the influence of lifestyle on the severity of melasma. This was a cross-sectional study involving 75 patients of both sexes diagnosed with melasma, who answered three questionnaires: the Melasma Quality of Life Scale (MelasQoL), the Individual Lifestyle Profile Scale, and the EAS-40 scale, in addition to being evaluated using the Melasma Area and Severity Index (MASI). The mean age was 37.5 years, 33% were undergoing medical treatment, 58% used cosmetic products, and 77% were exposed to sunlight at least once a week, while only 40% regularly used sunscreen, 17% were smokers, 40% reported alcohol consumption, and 21% used oral contraceptives. A significant association was found between lifestyle and MASI scores (r = ?0.62; p < 0.0001), as well as with the EAS-40 scale (r = 0.59; p < 0.0001), and the odds ratio for smoking was 2.4. It is concluded that a negative lifestyle may contribute to greater severity of melasma.
