Pustules are small, raised bumps on the skin that are filled with pus. They can appear in various skin conditions, such as acne, chickenpox, or impetigo. Pustules are typically red at the base and can be painful or itchy. They may vary in size and can occur anywhere on the body. These skin lesions are a result of inflammation and infection, often caused by bacteria or viruses. Treatment for pustules usually involves keeping the area clean and may include topical or oral medications, depending on the underlying cause. Proper care can help prevent scarring and further skin issues.
