Smile lines are the creases that run along the sides of the mouth. These lines become more visible as we age due to a decrease in collagen and elastin production, volume loss in the face, and repetitive facial expressions. While these lines are a natural part of skin aging, some people seek hyaluronic acid filler to help with them.
Dermal fillers are gel-like substances that are injected beneath the skin to restore volume, smooth out wrinkles, and enhance facial contours. When injected skillfully into or around the creases, they will soften and smooth the skin. Sometimes filler is needed in other locations around the mid-face and lower face to help lift and support the area.
