As we age, we begin to notice changes to our faces. Wrinkles may become more noticeable, our cheeks may appear more sunken in, our skin becomes drier and rougher, and our lips lose volume. Many of these changes have to do with a loss of naturally occurring substances found in our skin. Two of these substances include collagen and hyaluronic acid, which help give the skin structure and moisturize the skin. A Las Vegas Juvederm® treatment is one effective way to counter these aging effects.
