Radiesse (filler) and Complications
To smooth out wrinkles and add some volume to parts of the face, I prefer to use hyaluronic acid fillers like Juvederm or Restylane. Bumps or lumps occurring with Juvederm/Restylane can be reversed with the enzyme hyaluronidase. I see a higher rate of more serious complications with Radiesse, partly because it is made of calcium hydroxyapetite. Radiesse is also not reversible easily. Radiesse should never be used around the eye area or around or in the lips.
