Fillers are injected into the skin to soften facial lines and creases, restore lost volume or add increased volume, or enhance facial contours. Fillers can help deliver fuller lips, a refined nose, more prominent cheekbones, a brighter under-eye area, and fewer wrinkles. Fillers have little or no downtime and results are immediate and can last 6 months to 2 years depending on the type of filler, the individual, and the application area.
