What is a common factor associated with the aging of the skin?

The aging of the skin is significantly influenced by exposure to UV rays. Ultraviolet (UV) radiation from the sun can damage the DNA in skin cells, leading to premature aging, which manifests as wrinkles, loss of elasticity, and uneven skin tone. Over time, cumulative sun exposure can deplete collagen and elastin in the skin, essential proteins that maintain firmness and elasticity. Because UV rays cause oxidative stress, they contribute to oxidative damage, a key factor in the skin aging process.

Hydration is often considered beneficial for the skin, and while hydration is essential for maintaining skin health, it does not directly contribute to the aging process in the same way that UV exposure does. The use of herbal products and the consumption of antioxidants may support skin health but are not commonly recognized as primary factors in the aging process. In contrast, UV exposure is a well-established environmental factor that significantly accelerates skin aging.
