← Human Body & HealthWhy does skin elasticity decrease in elderly individuals more rapidly than in younger individuals after equivalent UV exposure?
A)Increased melanin production prevents degradation
B)Enhanced fibroblast activity maintains collagen
C)Reduced collagen cross-linking impairs repair✓
D)Elevated elastin synthesis supports dermis
💡 Explanation
Reduced collagen cross-linking impairs the skin's ability to repair UV-induced damage because cross-links provide structural integrity essential for recovery. Therefore, elasticity decreases more rapidly in the elderly, rather than melanin production, fibroblast activity, or elastin synthesis preventing or reversing the damage.
