Mask Acne (Maskne): A New Variant of Acne Mechanica
Paichitrojjana A Mail

Mask acne (maskne) is the new variant of acne mechanica, associated with personal protective equipment usage in healthcare workers. Widespread daily use of facial masks for many hours during the COVID-19 pandemic has been linked to the development of new acne or exacerbation of the previous acne over the masked area, with a distinct pattern, referred to as the “O” zone area around the mouth. Maskne can be caused by friction, irritation, local increase in skin temperature, and humidity, the same mechanism as observed in acne mechanica.
