Sculptra™ / New Fill™ (poly-l-lactic acid) is a synthetic injectable material that provides a gradual and significant increase in skin thickness and is used for the correction of fine lines, wrinkles and furrows or creases, as well as for the augmentation of cheeks, chin and lips. It has been used for over 5 years in 33 countries worldwide. SCULPTRA™ is composed of poly-l-lactic (PLLA) acid, a synthetic substance that is biodegradable and bio-compatible. SCULPTRA™ works by providing a framework for your body to produce and lay down collagen, which fills in the desired area. There’s no pre-treatment skin test, and, unlike surgery, little to no downtime. Most people usually return to work or normal activities immediately. SCULPTRA™ is long lasting but not permanent.
