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, sports injuries, or accidents. These wounds typically affect the outer layer of skin, known as the epidermis, and can vary in size and depth. While abrasions are usually minor and heal on their own, they can sometimes lead to infection if not properly cleaned and cared for. It's important to keep the area clean and covered to promote healing and prevent complications. Proper first aid can help minimize discomfort and reduce the risk of scarring.
