What Causes Wrinkles?
Our skin consists of two layers: the outer layer and another layer below it. Wrinkles happen in the below layer that is made up of collagen and other proteins. The collagen is the main structural protein found in skin and other connective tissues is often considered the glue that holds the body together. And it is what makes our skin elastic and smooth. As we age, our bodies produce less collagen, which results in saggy skin with wrinkles.
