A closed comedone is commonly referred to as a whitehead. This type of comedone occurs when hair follicles become clogged with sebum, dead skin cells, and sometimes bacteria, leading to the formation of a small, flesh-colored bump on the skin's surface.

Understanding the terminology in dermatology and esthetics is crucial for accurate identification and treatment of skin conditions. Recognizing that a whitehead is a closed comedone helps in distinguishing it from other types of acne lesions and highlights the importance of proper skincare and treatment approaches for various forms of acne.
