Acne mechanica is a form of acne caused by friction, pressure, heat, and occlusion against the skin. This type of acne is commonly seen in athletes, military personnel, and individuals who wear tight clothing or equipment for extended periods. The repeated mechanical stress on the skin leads to clogged pores and inflammation, resulting in the formation of acne lesions such as papules, pustules, and nodules. Recognizing the signs and triggers of acne mechanica is essential for effective prevention and treatment. Simple adjustments to clothing and hygiene routines can significantly reduce the risk of developing this condition.
