What is a long-term effect of overexposure to UV radiation?

Overexposure to ultraviolet (UV) radiation has several negative long-term effects on the skin, one of which is premature aging. This occurs because UV radiation damages the DNA in skin cells, leading to a breakdown of collagen and elastin fibers, which are critical for maintaining the skin's structure and elasticity. As this structural integrity diminishes, the skin becomes more prone to wrinkles, fine lines, and discoloration. This phenomenon is often referred to as "photoaging," which includes not only aesthetic changes but also an increased risk of skin conditions such as skin cancer. Therefore, recognizing the effects of UV radiation is crucial in promoting skin health and taking preventative measures against excessive sun exposure.
