What is a papule?

A papule is defined as a small, raised, solid pimple or swelling. Specifically, it is a type of primary lesion that is typically less than one centimeter in diameter and can vary in color from red to brown. Papules are often a result of various skin conditions, including acne, dermatitis, or other inflammatory processes. They are characterized by their palpable nature and lack of fluid, making them distinct from vesicles, which are small fluid-filled blisters.

Understanding the characteristics of papules is crucial for estheticians, as they can indicate underlying skin issues that may need to be addressed through appropriate treatments or referrals to dermatologists. This knowledge also helps in differentiating papules from other skin lesions, which have different implications and treatment approaches.
