What is photoaging skin and how does prolonged sun exposure contribute to its development?

Photoaging skin refers to premature aging of the skin caused by prolonged exposure to the sun's harmful UV rays. This exposure can lead to the breakdown of collagen and elastin fibers in the skin, causing wrinkles, fine lines, age spots, and sagging skin. Over time, repeated sun exposure can accelerate the aging process, making the skin appear older than it actually is. It is important to protect the skin from the sun by using sunscreen and wearing protective clothing to prevent photoaging.
