Radiesse is a synthetic calcium hydroxyapatite filler. Calcium hydroxyapatite is the stuff that makes up your bone. The Radiesse people have made a synthetic version of this compound that is injected as a gel. The gel is great as a filler for deeper folds and wrinkles. It is great for the nasolabial folds, grooves under your eyes and any larger volume loss on your face. It lasts for about one
year, although Bioform would like you to believe it lasts longer than that. One of the wonderful things about Radiesse is that it expends when injected and takes up more space than the other fillers. For example, to fill in a single area, studies have shown that 1.2cc of Radiesse will fill the same amount as 2.4 cc of collagen.
