Acne Mechanica Treatment Guidelines Handout

Acne mechanica is a type of acne caused by repetitive friction on the skin. Typically, the skin will become sensitive and inflamed, and breakouts will appear that can be itchy, uncomfortable or painful.

Acne mechanica forms when clothing or sports gear such as helmets repeatedly rubs against the skin. This obstructs pores, causing a build-up of sebum, dead skin cells and bacteria, leading to breakouts. Acne mechanica is especially common after long or frequent periods of exercise, as sweat, heat, and friction can exacerbate acne-causing bacteria.

Acne mechanica may go away on its own if the affected skin is not exposed to any further friction or irritation. However, over the counter topical medications with ingredients like benzoyl peroxide and salicylic acid are often necessary. In severe cases of acne mechanica, prescription acne medication may be required. Treatment typically takes several weeks, depending on symptom severity.
