Our bodies produce collagen, elastin and hyaluronic acid. Each of these substances play a role in keeping skin plump, supple, and hydrated. As you age, your skin becomes thinner and dry because the body decreases its production of these compounds.
Dermal fillers add volume and lift to your skin. Each injection is administered with a tiny needle filled with a gel that reduces the appearance of wrinkles and fine lines. Many injectables contain HA, which is a biocompatible substance. In other words, HA appears naturally in the body, so it's absorbed into the body without any adverse effects and the body has the ability to break it down.
