What are dermal fillers?
Dermal fillers – Juvederm, Restylane, Belotero, and Voluma– contain some form of hyaluronic acid, a substance that naturally occurs throughout the body and skin, with the highest concentrations in the fluids of the eyes and joints. Radiesse is a calcium hydroxyapatite filler, while Sculptra contains L-poly-lactic acid. Fillers can be used to temporarily plump lips, raise depressed scars and level wrinkled skin.
First, the doctor marks the areas to be injected. Topical or injection numbing medication may be used for added comfort. Then the fillers are injected by syringe using very fine needles. The effect typically lasts about six months. After that, additional injections are required to maintain the effect.
