Abrasion: Definition, Causes, and First-Aid Treatment

An abrasion is a superficial skin injury where the epidermis is scraped off, exposing the dermis, often with minimal bleeding.

Common Causes

• Falls on rough surfaces (pavement, gravel)
• Friction from sports equipment or clothing
• Accidental scratches

Basic Care

1. Clean gently with saline or mild soap/water.
2. Apply thin antibiotic ointment (e.g., bacitracin).
3. Cover with non-adherent dressing.
4. Change daily; monitor for infection (increasing redness, pus, warmth).

Most heal within 7–10 days without scarring.
