Acne mechanica is form of acne caused by irritations, most commonly found on the back. Acne mechanica is the result of something rubbing against the skin repeatedly such as backpacks or weightlifting machines. Over the shoulder straps can also irritate the skin on the chest.
Why does it occur. Acne occurs when glands (called sebaceous glands) in the follicles of the skin become overactive. These glands produce sebum, an oily substance that helps to stop the skin drying out.Someone with acne produces too much sebum, which forms a plug with dead skin cells and blocks the follicle.If the blocked follicle is close to the skin surface, it balloons outwards and forms a whitehead.everal factors can cause acne to get worse: 1  Changing levels of hormones in teenage girls and women, usually two to seven days before their period starts. 2  Oil from skin products, such as moisturisers and make-up, or grease in the workplace (such as a kitchen with fryers).
