Texas Class A Barber Written ExamShaving and Facial ServicesMedium
A barber is performing a skin analysis and observes several comedones, both open (blackheads) and closed (whiteheads), on a client's T-zone. Which underlying skin condition is primarily responsible for the formation of comedones?
- ALack of collagen
- BDehydrated skin
- CExcess sebum production
- DHypopigmentation
Show answer & explanationAnswer & explanation
Correct answer: C. Excess sebum production
Comedones (blackheads and whiteheads) are formed when hair follicles become clogged with a mixture of dead skin cells and excess sebum (oil). Therefore, excess sebum production is a primary underlying factor in their formation.
Why the other options are wrong
- A. Lack of collagen is associated with aging skin and loss of elasticity, not comedone formation.
- B. Dehydrated skin lacks water, but its primary effect is not the formation of comedones; it can sometimes worsen acne but isn't the direct cause of blockages.
- D. Hypopigmentation refers to light spots on the skin due to a lack of melanin, unrelated to comedones.
Comedone Formation
Comedones (blackheads and whiteheads) form when hair follicles become clogged with a mixture of dead skin cells and excess sebum, leading to blocked pores.
- Clogged hair follicles.
- Mixture of dead skin cells and sebum.
- Results in blackheads (open) or whiteheads (closed).
Memory trick: Oil and Cells Clog, Comedones Grow.
