Whiteheads are also known as which form of clogged pore?

• A. Blackheads
• B. Vesicles
• C. Closed comedones
• D. Open comedones

Answer: (C)

Whiteheads occur when a pore becomes clogged but stays closed at the surface. The sebum and dead skin cells plug the follicle and are sealed off by a thin layer of skin, forming a small, white or flesh-colored bump called a closed comedone. If the opening of the pore remains open, the material is exposed to air and darkens, producing a blackhead (an open comedone). Vesicles are fluid-filled sacs from other skin conditions and are not clogged pores, so they don’t describe whiteheads. Hence, whiteheads are closed comedones.
