Sagging skin is primarily caused by the natural aging process, as the production of collagen and elastin—proteins that provide skin with firmness and elasticity—declines over time. This loss leads to skin loosening and sagging. Sun exposure accelerates this process, causing photoaging and further weakening of the skin’s support structure. Other factors, such as smoking, dehydration, poor diet, and a lack of sleep, can also contribute by damaging the skin’s ability to regenerate and maintain moisture.

Lines and wrinkles are primarily caused by the natural aging process, as skin loses collagen, elastin, and hyaluronic acid, which are essential for maintaining firmness and elasticity. Sun exposure accelerates this breakdown, leading to photoaging and the development of fine lines, particularly around the eyes and mouth. Repeated facial expressions, such as smiling or frowning, cause dynamic wrinkles that deepen over time. Smoking, poor diet, and dehydration also contribute by reducing skin’s ability to regenerate and maintain moisture.
