What effect does excessive UV exposure have on the skin over time?

Excessive UV exposure can lead to premature skin aging and damage due to the harmful effects of ultraviolet rays on the skin's structure. Over time, repeated exposure to UV radiation can break down collagen and elastin fibers, which are crucial for maintaining skin elasticity and firmness. This degradation contributes to visible signs of aging, such as wrinkles, fine lines, and sagging skin. Additionally, UV exposure can cause hyperpigmentation, such as sunspots, and increase the risk of developing various skin conditions, including skin cancers. Thus, the acknowledgment of the long-term detrimental effects of UV rays on skin health is vital for promoting proper sun protection and skin care practices.
