A typical session can be 10 to 20 syringes of Radiesse. When trying to achieve volume gain, multiple sessions may be needed with each session 6 to 8 weeks apart. We recommend that you come in for a free consultation with one of our doctors. They will determine whether you are a good candidate for the Radiesse Butt Lift. They will also discuss the number of vials and procedures needed to achieve the desired outcome.
