Detailed answer

Elastin is a protein that is responsible for giving elasticity to the skin. It allows the skin to stretch and bounce back to its original shape. As we age, the production of elastin decreases, resulting in loss of elasticity and sagging skin. Factors such as sun exposure, smoking, and genetics can also contribute to the breakdown of elastin. To minimize sagging skin, it is important to protect the skin from sun damage, maintain a healthy lifestyle, and use skincare products that promote collagen and elastin production.
