Detailed answer

Skin elasticity refers to the ability of the skin to stretch and then return to its original position. It is primarily determined by the presence of elastin and collagen fibers in the skin. These fibers provide support and strength to the skin, maintaining its firmness and tightness. As we age, the production of elastin and collagen decreases, leading to a loss of skin elasticity. When the skin loses its elasticity, it becomes more prone to sagging, wrinkles, and fine lines. Factors such as sun exposure, smoking, and poor diet can further accelerate the breakdown of elastin and collagen fibers, exacerbating sagging skin. To maintain skin elasticity and prevent sagging, it is important to protect the skin from harmful UV rays, maintain a healthy diet, and use skincare products that promote collagen production.
