My fill person told me 3 to 4 fills until most of her clients hit there sweet spot. Dr. Ortiz says o average 2 -3 fills. But many people get more than that. It just depends on how much you need to lose, your habits, how aggresive your fill doctor is, how much you work you put into it yourself, and how you did on your post-op diet. I am sure even more things contribute to it but I do not know them all. For sure it is easy to say it is not going to be the same for everyone.
