- Acne Mechanica

This form of acne is caused by external mechanical forces like constant pressure, constant and repeated friction, covered skin, and heat. For those involved in sports, in the military or in high-activity jobs, this is nothing new as the condition is common with many athletes and in professions where factors like tight-fitting, even restrictive clothing is worn for extended periods of time. These sort of jobs may include certain kinds of factory work where an employee may be busy with repetitive tasks that may irritate the skin and lead to break outs.

For soldiers who must wear uniforms much of the time and may be carrying backpacks with straps that bite into the skin and cause friction with each step or straps on weapons that can also rub again the body this can become a real issue. Operating in the extremes of temperatures that these soldiers often do can also often complicate existent acne by causing inflammation and further breakouts.

Further examples of possible causes may include:

 Wearing head bands that can rub the forehead and irritate the skin
 The kind of friction caused by physical contact with musical instruments
for extended periods of time
 Wearing tight clothing period; whether it is blue jeans or types of
undergarments made with synthetic materials
 Even bra straps if they happen to fit snuggly against the skin
