Has been in the market since 2006, this one is slightly different in that it is a volumizing filler used to plump up moderate to severe facial wrinkles and to restore lost volume, such as the nasolabial folds and the cheeks. However, it is so much more than just a volumizing filler.
Unlike hyaluronic acid fillers this filler works by stimulating your body to produce collagen. It is made of Calcium Hydroxyapatite (CaHA) microspheres suspended in an aqueous gel carrier. When injected, it immediately adds volume to deficient areas and contours facial features. Over time, the gel is fully absorbed and the body uses up the CaHA microspheres (which are a component of collagen), leaving behind your own natural collagen.
It was first FDA approved in 2006 for treating folds and wrinkles in the face and in 2015, it also received FDA approval for treating volume loss in the back of the hands. To date, it is the only dermal filler approved for this purpose.
This filler provides an immediate lift by restoring lost volume in the treated areas, such as the cheeks and temples. It corrects deep facial folds such as the nasolabial lines and results continue to improve over the next 3 months. The skin becomes smoother and firmer when the CaHA particles stimulate collagen in your skin with associated tightening to pull the skin upwards and improve facial contours.
Lastly, this filler can be hyper-diluted and used primarily as a skin rejuvenator –when the procedure is performed this way, the skin rejuvenating effects are even more pronounced and visible – suitable for annual rejuvenation of sundamaged, worn areas such as the face, neck, decolletage and hands.
