Originally approved by the FDA to fill in hollowed cheeks of the ultra thin patients is now being used to give facelifts. The procedure does not carry the risk of general anesthesia and only takes 20 minutes. The filler is injected under the skin to increase natural collagen production in areas like the cheek and chin adding strength and volume to the face thereby lifting sagging of the jowls, cheeks and neck. And it is lasting an unprecedented 2-3 years.
