Prevention of acne mechanica involves minimizing mechanical stress on the skin. Wearing loose, breathable clothing made of natural fibers can help reduce friction and allow the skin to breathe. Properly fitting sports gear and helmets, with padding or moisture-wicking liners, can prevent pressure and sweat buildup. Regularly washing and changing clothes, especially after sweating, helps keep the skin clean and dry. Using non-comedogenic skincare products and avoiding occlusive ointments or creams can prevent pore blockage. Implementing these preventive measures can significantly reduce the occurrence of acne mechanica.
