Which gland is commonly associated with acne development?

• A. Eccrine gland
• B. Sebaceous gland
• C. Apocrine gland
• D. Mammary gland

Answer: (B)

Acne development is closely tied to the sebaceous glands because these oil-producing glands sit next to hair follicles and respond to hormonal signals (like androgens) by increasing sebum production. When sebum combines with dead skin cells, it can clog the hair follicle, creating a plug or comedone. The trapped environment allows bacteria such as Propionibacterium acnes to proliferate, leading to inflammation and pimples. Eccrine glands are sweat glands for temperature regulation, apocrine glands contribute to body odor and aren’t the primary drivers of acne, and mammary glands produce milk. So the gland most associated with acne development is the sebaceous gland.
