Acne mechanica

Acne mechanica is a specific subtype of acne that is triggered by excess heat, pressure, friction, or rubbing of the skin. It is commonly seen in athletes, students, and individuals who wear tight clothing or equipment for extended periods. This condition is characterized by the appearance of small, rough bumps, which can develop into inflamed papules and pustules, primarily in areas where the skin is subjected to constant mechanical stress.

Causes and Risk Factors

Acne mechanica is caused by the blockage and irritation of hair follicles due to mechanical stress on the skin. This stress can be due to various factors, including:

• Tight clothing or equipment that traps heat and sweat against the skin
• Heavy backpacks or gear that rubs against the skin
• Prolonged use of medical devices, such as splints or braces
• Environmental factors that increase sweating and friction

Individuals who are already prone to acne vulgaris are at a higher risk of developing acne mechanica. Athletes, military personnel, and people who engage in physical activities that require wearing protective gear are particularly susceptible.

Symptoms

The primary symptoms of acne mechanica include:

• Small, rough bumps on the skin
• Red, inflamed papules and pustules
• Areas of skin irritation and tenderness
• Occurrence in areas subjected to pressure, friction, or heat

Prevention and Treatment

Preventing acne mechanica involves reducing skin irritation and avoiding conditions that promote excessive sweating and friction. Some strategies include:

• Wearing loose, breathable clothing
• Using moisture-wicking fabrics
• Placing barriers, such as pads or bandages, in high-friction areas
• Maintaining a regular skincare routine to keep the skin clean and hydrated

Treatment options for acne mechanica are similar to those for other forms of acne and may include:

• Topical treatments, such as benzoyl peroxide or salicylic acid
• Oral medications, including antibiotics or isotretinoin, for more severe cases
• Lifestyle modifications to reduce skin irritation and improve hygiene
