Radiesse for neck tightening. Which type of aftercare instructions should I follow? 74 y/o female

Female, 74. I am interested in radiennse for my neck but received different information from doctors for post injections. I was told that I should not massage afterwards from 1 and the other said not to massage to leave it alone cause he molds it to my neck. I'm confused as to going to either one for my procedure, just wondering what you advise!
