Which statement best defines extrinsic aging?

• A. It is influenced by genetics
• B. It occurs solely due to aging
• C. It is not influenced by lifestyle
• D. It is influenced by external factors such as sun exposure, smoking, and alcohol

Answer: (D)

Extrinsic aging refers to skin aging driven by external factors and environment rather than just the passage of time. This is why sun exposure, smoking, and alcohol are classic influences—they actively accelerate aging processes in the skin, producing photoaging, wrinkles, dullness, and uneven pigmentation. In contrast, intrinsic aging is governed mainly by genetics and the body’s natural aging clock, largely independent of lifestyle. So the statement that extrinsic aging is influenced by external factors such as sun exposure, smoking, and alcohol captures the correct idea.
