How Do Juvederm Fillers Work?

Juvederm is made of hyaluronic acid, a naturally occurring substance that hydrates and attracts water to the skin. The injectable gel adds volume, and this added volume helps smooth the appearance of fine lines, wrinkles, and sunken cheeks. The hyaluronic acid in Juvederm works to hydrate the skin, but additional treatments are typically needed to address lines and wrinkles.
