Fillers do exactly as their name implies, they fill. Most fillers on the market are made from hyaluronic acid (HA) which is a gel-like substance found throughout the body. They come packaged as pre-filled, sterile syringes with slightly different properties across brands and products. Each filler is specifically selected by your provider for your unique skin, type of correction needed, and desired outcome. Fillers can be used to smooth deep and fine lines, augment existing structures like the lips, chin and cheeks, contour facial shapes, and minimize the signs of aging by lifting tissues where volume has been lost. Injections are most common in the face but can be used behind the hair line to lift the lower face and in the neck, arms and legs.
