When I first had a filler on my cheeks was 10 years ago. Unfortunately the left side cheek has not dissolve over the 10 years but the right side was dissolving and I had to refill it every year.last time that I have done my right cheek was 20 months ago with radiesse it is over sized and I'm not happy with the shape and size at all. It's annoying me. I consulted with a few doctors and they said that I have to do surgery to remove them.what is going to happen to my tissue and skin after surgery?
