An informal definition of a face mask is a covering worn over the nose and mouth, often made of cloth, paper, or other materials, designed to protect the wearer from inhaling harmful particles or to prevent the spread of germs to others. Face masks are commonly used in healthcare settings, during pandemics, or in environments with dust or pollutants. They can also be used for cosmetic or skincare purposes, such as facial masks applied for cleansing or moisturizing.
