Background: Melasma is a common acquired hyperpigmentary disorder characterized by irregular light or dark brown macules in sunexposed areas of skin. It is a consequence of specific hyperfunctional melanocytes that cause excessive melanin deposition in skin. Aims – Our present research aims to study the clinico–epidemological profile and precipitating and aggravating factors of melasma. Material and methods – Three hundred patients of melasma attending out–patient department of dermatology were included in the study. Results – The mean age of melasma patient in our study was 32.3 years with the female to male ratio of 3:1. The mean age of onset was 26.87 years. The mean duration of disease in present study was 6.23 years. Centrofacial melasma and epidermal type were the most common pattern seen. Familial predisposition, pregnancy, sun–exposure were the most common triggering factors observed. Conclusion – The study indicates was melasma has a wide variation in its clinico–epidemological profile and many factors are involved in its etiopathogenesis.
