As we get older, our skin begins to lose collagen, which is the main binding protein in the skin of mammals. The result, as you probably have already seen, is skin changing from smooth and young to wrinkled and old. I know that sounds harsh, but there's really no getting around it. Our skin will gain wrinkles as we age, and it's simply a matter of nature. What matters, I think, is the way that we think about our skin. Do those wrinkles show character and wisdom? If so, then why would we go out into the world worried about them?
