What is the term for a non-inflamed buildup of cells, sebum, and debris inside follicles?

  1. Comedo

  2. Milia

  3. Steatoma

  4. Bromidrosis

The correct answer is: Comedo

The term for a non-inflamed buildup of cells, sebum, and debris inside follicles is known as a comedo. This term specifically refers to the type of acne formation that occurs when a hair follicle becomes clogged with dead skin cells and oil, but without any surrounding inflammation. In the context of skin care and esthetics, understanding comedones is essential because they can lead to more severe forms of acne, such as pustules or papules if they become inflamed. Comedones can present as open (blackheads) or closed (whiteheads), both of which are critical for estheticians to recognize and treat properly. Other terms associated with skin conditions serve different meanings—milia are small, white cysts that appear often around the eyes and cheeks but are distinct from comedones. Steatoma refers to a sebaceous cyst filled with sebaceous gland products, while bromidrosis refers to a foul odor from sweat and does not pertain to follicular build-up. Understanding these distinctions is important for effective skin assessment and treatment in esthetic practices.
