Intrinsic aging is primarily influenced by which factor?

Intrinsic aging is primarily influenced by which factor?

• A. External sun exposure
• B. Dietary choices
• C. Genetic factors
• D. Personal habits

Answer: (C)

Intrinsic aging is the body's natural aging process driven by internal biology. It follows a genetic program built into our DNA, so the rate and pattern of aging from within are largely determined by genetic factors. External sun exposure and other environmental influences cause different aging effects—like sun-induced photoaging—which accelerate visible signs but don’t establish the baseline aging process. Diet and personal habits can influence skin health and how quickly signs appear, but they act as modifiers rather than the primary driver of intrinsic aging. So, genetic factors are the main influence on intrinsic aging.
