Collagen and elastic compounds give skin a youthful shape and appearance. Collagen is composed of tightly-constructed fibers, which helps skin maintain its structure and firmness. In contrast, elastin provides skin elasticity, allowing the skin to bounce back when stretched. As we age, both of their productions are reduced and lead to saggy loose skin. While the aging process cannot be reversed, we can do something to slow it down or reduce the appearance of sagginess.
