Question: 1 / 400

What are open comedones commonly referred to as?

Whiteheads

Blackheads

Open comedones are commonly referred to as blackheads. This term specifically describes a type of acne that occurs when hair follicles become clogged with sebum (oil) and dead skin cells. Unlike whiteheads, which are closed comedones, blackheads are characterized by their open surface that exposes the clogged material to air. This exposure causes the material to oxidize, giving it a dark appearance, hence the name "blackhead."

The distinction between open and closed comedones is important in dermatology, as it helps in understanding different types of acne lesions and determining appropriate treatment options. Understanding these differences is crucial for effective patient education and management in clinical practice, especially in acute care settings.
