Disease characteristics, determinants, and perception of use of sunscreen and sun‐protective behaviors among patients of color with melasma: A cross‐sectional study

Background Melasma is an acquired state of hyperpigmentation that most commonly affects the face. The use of sunscreen is essential in melasma treatment.
