Can applying facial masks frequently reduce the formation of melasma?

Using face masks frequently generally cannot significantly reduce the formation of melasma. The primary benefits of face masks typically lie in hydrating, moisturizing, and repairing the skin, with relatively minimal effects on lightening pigmentation. Melasma has complex and varied causes, including ultraviolet radiation, endocrine disorders, genetic factors, medications, and others. Therefore, reducing melasma formation requires targeted treatments addressing the specific causes, such as enhanced sun protection, regulation of endocrine function, and avoiding medications that may trigger melasma. Additionally, for existing melasma, medical aesthetic treatments such as laser therapy may be considered for improvement. Frequent use of face masks alone should not be regarded as the primary treatment for reducing melasma formation; a comprehensive approach combining multiple preventive and therapeutic methods is necessary.
