If left untreated, acne mechanica can lead to significant complications, including persistent acne lesions, skin irritation, and scarring. The continuous friction and pressure on the skin can cause deeper, more painful nodules that are harder to treat and more likely to scar. Additionally, the psychological impact of visible and painful acne can lead to decreased self-esteem and social withdrawal. Timely diagnosis and treatment are crucial to prevent these complications and maintain healthy skin. Implementing preventive measures and adhering to treatment plans can effectively manage acne mechanica and its potential complications.
