Radiesse (dermal fillers) (calcium hydroxylapatite)is a good volumizing facial filler that can last 1 year. It is better than than the various hyaluronic acid fillers (restylane, juvederm) for deeper areas and for more longevity.
In general, fillers (Hyaluronic Acids) last from 6 months to a year. How long fillers last depends on: 1) the amount injected, 2) the location of placement and 3) the number of repeated injections. Placement in areas of motion (nasolabial folds and lips) cause the filler to dissipate more rapidly; whereas, injection in the tear trough region tends to be apparent longer.
