Skin SciencesQuestion 48 of 100
Which pair correctly separates intrinsic from extrinsic aging?
a.Both are entirely genetic and cannot be influenced
b.Both are caused only by lifestyle choices
c.Intrinsic aging is caused by smoking; extrinsic aging is genetic
d.Intrinsic aging is the genetically programmed decline over time; extrinsic aging comes from external factors such as UV exposure, smoking, and pollution
Explanation
Intrinsic aging reflects genetics and the passage of time, producing gradual thinning and loss of collagen, while extrinsic aging is driven by controllable external exposures, with sun exposure the largest single contributor. The two are distinct but overlapping, and only the extrinsic component is meaningfully modifiable through sun protection and lifestyle.
