Dear Dr. Irwin, I've read and really like both of your books (your Best Face and Surgery-Free Makeover). I'd like to try Thermage based on your recommendation in your book. However, I have a metal plate in my left shoulder which was put in about 5 years ago when I had a surgery to fix my broken collar bone. Is it safe for me to do Thermage or other similar type of radio frequency treatments for sagging skin? The metal plate was about 5 cm long,0.8 cm high and 0.5 cm wide. Thank you very much.
