What effect does UVA radiation have on the skin?

Causes skin peeling
Contributes to sunburn
Weakens collagen and elastin fibers
Cleanses the skin

The correct answer is: Weakens collagen and elastin fibers

UVA radiation has a significant influence on skin aging and the structural integrity of the skin. When UVA rays penetrate deeply into the skin, they can damage collagen and elastin fibers, which are crucial for maintaining skin's elasticity and firmness. This breakdown can lead to the formation of wrinkles, premature aging, and a loss of skin tone. Unlike UVB radiation, which primarily causes sunburn, UVA rays are consistent year-round and can even penetrate through windows, making their damaging effects a chronic concern for skin health. The other options do not accurately describe the specific impact of UVA radiation. Skin peeling is typically associated with sunburn, which is more directly caused by UVB rays. The contribution of UVA to sunburn is minimal compared to UVB. As for cleansing the skin, this is not a function of any type of UV radiation; rather, cleansing is achieved through the use of skincare products designed for that purpose. Thus, recognizing the damaging effects of UVA rays on collagen and elastin strengthens our understanding of skin care and the need for protective measures like broad-spectrum sunscreen.
