What is a common effect of overexposure to UV light?

• A. Decreased collagen production
• B. Improved skin elasticity
• C. Enhanced skin hydration
• D. Reduced skin sensitivity

Answer: (A)

Overexposure to UV light primarily results in decreased collagen production in the skin. Collagen is a vital protein that provides structure, strength, and elasticity to the skin. When the skin is exposed to UV radiation, it can lead to direct damage to collagen fibers and the dermal layer where collagen is produced. This degradation negatively impacts the skin's ability to maintain its firmness and resilience over time, contributing to premature aging, wrinkles, and a loss of smoothness. In contrast, options that suggest improved skin elasticity or enhanced skin hydration are not accurate outcomes of UV overexposure. Rather, prolonged exposure can lead to a decrease in these qualities. Additionally, the notion of reduced skin sensitivity is misleading, as UV exposure often makes the skin more reactive and sensitive due to irritation and potential sunburn. Thus, the effect of decreased collagen production directly correlates with the damaging effects of UV light on the skin.
