Which type of rays is most responsible for the aging effects on skin?

UVB rays
UVA rays
Infrared rays
X-rays

The correct answer is: UVA rays

UVA rays are primarily responsible for the aging effects on the skin. These rays penetrate deep into the skin layers, causing damage to collagen and elastin, which are crucial for maintaining skin elasticity and firmness. Over time, this damage leads to premature aging signs such as wrinkles, fine lines, and loss of skin tone. Unlike UVB rays, which are more associated with sunburn and have a more direct effect on the surface of the skin, UVA rays can cause cumulative damage even on overcast days or through windows, making their effects particularly insidious. Therefore, understanding the role of UVA rays is essential for effective skincare and protection against photoaging.
