Chances are, you’re familiar with Radiesse. Since gaining FDA approval in 2006, some 6 million syringes of the filler have been injected deep in the skin, to restore lost volume and correct facial wrinkles and folds. Radiesse is frequently used to smooth smile lines, lift sunken cheeks, plump hands, and strengthen jawlines. Recently, however, dermatologists and facial plastic surgeons have started using Radiesse in a unique way, by diluting (or when the ratio is 1:2 or higher, hyperdiluting) it with saline or lidocaine and injecting it more superficially, to address concerns related to skin texture and laxity—think fine wrinkles, crepiness, acne scars, and cellulite as well as saggy skin. It’s being used on the face, neck, chest, arms, abdomen, legs, and buttocks.
