Abrasions are injuries that occur when the skin is scraped or rubbed off, often due to friction against a rough surface. Common causes include falls, accidents, or contact with sharp objects. These injuries typically affect the outer layer of skin, known as the epidermis, and can vary in severity from minor scrapes to deeper wounds. Treatment for abrasions usually involves cleaning the affected area to prevent infection and applying a sterile bandage. It's important to keep the wound clean and dry while it heals. In some cases, if the abrasion is deep or shows signs of infection, medical attention may be necessary.
