What is acne mechanica?
Acne mechanica is an inflammatory skin condition in which repeated rubbing or pressure on the skin causes breakouts and skin irritation. Friction and pressure from mask-wearing, tight clothing, or sports equipment trap heat, dead skin cells, and bacteria, causing a patient to develop acne mechanica.
Acne mechanica presents similarly to other types of acne, such as acne vulgaris. Redness, pimples, raised itchy bumps, papules, and pustules are all frequent symptoms and tend to form in areas such as the inner thighs or under the bra, where chafing, friction, and sweating are common.
Skin sensitivity is a common result of acne mechanica, and sensitive skin is more prone to breakouts. This means those with acne mechanica often experience a vicious cycle in which the affected areas do not have sufficient time to heal between exposure to friction or irritants, leading to continual or worsening symptoms. Untreated acne mechanica may develop into severe inflammation.
People with preexisting acne are more prone to developing acne mechanica, but unlike regular acne it is typically caused by external trauma to the skin. Acne mechanica is a relatively preventable and treatable form of acne.
