Sagging skin on the face is mainly caused by the natural aging process, which leads to a breakdown of collagen and elastin—proteins responsible for skin’s firmness and elasticity. Over time, facial fat pads shrink and shift downward, contributing to loose, sagging skin. External factors like sun damage, smoking, dehydration, and nutrient deficiencies accelerate collagen breakdown and weaken the skin’s structure. Additionally, gravity and repeated facial movements gradually pull the skin downward, making sagging more noticeable.
