Detailed answer

Excessive sun exposure can lead to worsened sallow skin due to the damaging effects of ultraviolet (UV) radiation. UV radiation can cause the breakdown of collagen and elastin in the skin, leading to sagging and thinning of the skin. It can also trigger an increase in melanin production, resulting in uneven skin tone and dark spots. Additionally, prolonged sun exposure can cause dehydration and inflammation in the skin, further accentuating sallow appearance. To prevent and improve sallow skin, it is essential to protect the skin from the sun by using broad-spectrum sunscreen, seeking shade, wearing protective clothing, and avoiding peak sun hours.
