Acne mechanica frequently develops during the hot summer months. Athletes apparently move through their times of peak performance without as much as an ouch. But frequently after the intensity of athletic pursuit the damage becomes more noticeable. Along with sprang ankles and stress fractures--mechanical acne slowly comes into view.

Typically, small acne lesions occur in reddened patches of skin anywhere that athletic gear rubs during physical exertion. Acne mechanica results from the combination of friction, perspiration and decreased air circulation. Spandex and Lycra are particularly good as far as ease of movement is concerned but are the usual culprits in the causation of acne mechanica. Also notable offenders are elastic straps and tight fitting head gear.

Cotton jersey knits and newer breathable fabrics can be worn to reduce flare ups of this summer nuisance. Similarly products which absorb perspiration will help. Medicated powder and strong antiperspirants are helpful in this regard. When possible, it is better to wear looser fitting clothing that would also help cool and prevent this troublesome skin rash.

Once a breakout of acne mechanica has occurred, the forms of treatment are similar to those for other forms. As with nearly every form of acne, here too benzoyl peroxide can be used as a mild antibiotic and drying agent. For torso acne a solution of at least 7% can be used. Cystic acne of the torso may require even higher solutions. As much as 15% benzoyl peroxide can be used to treat these deep sacs of trapped sebum, p. acnes and infected follicular material.

Soaps containing a rather large amount of salicylic acid used immediately after training or competition are beneficial as exfoliates.

With a few minor changes in skin care and athletic gear the troublesome lesions associated with favorite recreational and competitive pursuits can be minimized or eliminated entirely.
