<unk>  is an acneiform eruption that has been observed after repetitive physical trauma to the skin such as rubbing, occurring from clothing (belts and straps) or sports equipment (football helmets and shoulder pads). In addition to those mechanisms, the skin not getting enough exposure to air also contributes to the formation of<unk> . It is often mistaken as a rash that forms on sweaty skin that is constantly being rubbed, but in reality, it is a breakout of<unk> . The term "acne" itself describes the occurrence in which hair follicles (also known as pores) in the skin get clogged by oil, dead skin cells, dirt and bacteria, or cosmetic products and create a pimple. Pimples can vary in type, size, and shape, but the sole basis of them occurring is the same - the oil gland in the pore becomes clogged and sometimes infected, which creates pus in order to fight the infection and subsequently causes the development of swollen, red lesions on the skin.
