A cosmetologist is performing a skin analysis on a client and observes small, dark, and hard-to-extract lesions, primarily on the nose and chin areas. The client reports a history of oily skin and occasional breakouts. Which type of comedone is the cosmetologist most likely observing?
- ABlackheads
- BPustules
- CWhiteheads
- DCysts
Show answer & explanationAnswer & explanation
Correct answer: A. Blackheads
Blackheads, also known as open comedones, are characterized by their dark appearance due to oxidized sebum and dead skin cells in the pore, making them small, dark, and often found in oily areas like the nose and chin.
Why the other options are wrong
- B. Pustules are inflamed, pus-filled lesions with a red base, not typically small, dark, and hard-to-extract.
- C. Whiteheads are closed comedones, appearing as small, flesh-colored or whitish bumps.
- D. Cysts are deep, painful, pus-filled lesions, much larger and more severe than what is described.
Blackheads (Open Comedones)
Small, dark lesions on the skin caused by clogged hair follicles, where the pore is open to the air, leading to oxidation of sebum and dead skin cells.
- Also known as open comedones.
- Appear dark due to oxidized sebum and melanin.
- Common in oily areas like the T-zone.
- Not indicative of dirt, but rather oxidized material.
Memory trick: Open doors let in the dark; closed doors keep it white.
