What characterizes a papule?

A papule is characterized as a raised area on the skin that is generally smaller than 1 centimeter. This definition aligns with the clinical terminology used in dermatology to describe various skin lesions. Papules are often solid lesions that can vary in color and texture, and they may be a result of a variety of skin conditions, including acne, eczema, or psoriasis.

Understanding the nature of a papule as a small, raised swelling is crucial for accurate identification and differentiation from other types of skin lesions. For example, a large bump filled with pus would typically be classified as a pustule instead of a papule. On the other hand, a flat discoloration of the skin is referred to as a macule, and an inflammatory condition encompasses a range of skin disorders that may involve papules but are not limited to them. The clear definition of a papule helps estheticians and other skincare professionals recognize and appropriately address various skin concerns.
