Detailed answer

Sun exposure accelerates sagging skin due to the harmful effects of ultraviolet (UV) radiation. UV rays penetrate the skin and damage collagen and elastin fibers, which are responsible for keeping the skin firm and elastic. Over time, this leads to a loss of skin elasticity, resulting in sagging. Additionally, sun exposure promotes the breakdown of the skin's supportive structures, such as hyaluronic acid, further contributing to sagging. It is essential to protect the skin from sun damage by using sunscreen with high SPF, wearing protective clothing, and seeking shade whenever possible to prevent premature sagging and maintain skin's youthful appearance.
