Underactive sebaceous glands typically result in _________.

• A. oily skin
• B. pore congestion
• C. dry skin
• D. dehydrated lips

Answer: (C)

When sebaceous glands are underactive, they produce less sebum, thinning the protective oil film that keeps skin moisturized. With less oil, the skin loses moisture and becomes dry, often feeling tight or looking flaky. The other options don’t fit because oily skin comes from too much oil, not too little; pore congestion is typically due to excess sebum and dead skin buildup; and dehydrated lips aren’t a direct result of facial sebaceous gland activity.
