Although we all know that skin changes as we age, it's not always easy to accept, especially as those changes become more pronounced. As the years pass by, the skin begins to lose collagen and elastin, making it thinner and sagging. Skin laxity is most prevalent on the face and neck, but it can occur anywhere in the body, including the arms, abdomen, and thighs. We will experience some amount of skin laxity as we get older. Still, the degree of laxity depends on many factors, including sun damage, exposure to pollution, diet, weight fluctuations, and lifestyle.
