I had chin surgery ( I was class II and had a mentoplasty to advance the chin a little bit) about 20 years ago. I was left with a few titanium screws and very small plates to secure the bone. Considering that I still have those tiny little metals inside, can I do Ultherapy on my face, jaw line and neck? Is there anyting I should be aware of and avoid in terms of non-surgical comestic treatments?
