Papule: Definition, Causes, Treatment - Skin Bump Explained

A papule is a small, raised, solid bump on the skin that is usually less than 1 centimeter in diameter. It is typically red, pink, or flesh-colored and may be accompanied by inflammation. Papules can be caused by various factors, such as acne, insect bites, allergic reactions, or skin infections. They are different from pustules, which are similar in appearance but contain pus. Treatment for papules depends on the underlying cause and may include topical creams, oral medications, or other interventions.
