Facial fillers such as Belotero, Radiesse and Juvederm Ultra help restore volume to support facial structures for a very natural youthful look. Hyaluronic acid is a substance found naturally in our bodies and is most commonly used. Radiesse has a calcium-base filler which provides support & helps stimulate collagen production. They are called “injectables” because they are injected into various sites where both patient and physician wish to see improvement.
