Detailed answer

Exposure to the sun's harmful ultraviolet (UV) rays can accelerate the breakdown of collagen and elastin, leading to sagging skin. Dry climates can cause dehydration and the loss of skin moisture, which can make the skin appear less firm and plump. Extreme temperatures, such as cold and hot weather, can also affect the elasticity of the skin, potentially leading to sagging. Additionally, some climates can expose the skin to high pollution levels, which can generate free radicals that damage collagen and contribute to sagging. It is important to protect the skin from the sun, moisturize regularly, and maintain a healthy skincare routine regardless of the climate to minimize the effects of sagging skin.
