I would strongly advise against the type of injections you are referring to. Even if you aren't a doctor, common sense alone should be a strong warning. Remember, if it is powerful enough to dissolve it, just imagine what else it is destroying in your body? Plus, remember that we have one circulatory system. Anything injected will be spread throughout your entire body to at least some degree, including your vital organs.
Regarding Ann Arbor plastic surgeons, unfortunately I will not be a great deal of help. I do have a friend that was operated on by a doctor in or around Detroit (I believe for a tummy tuck) but do not know the price paid or remember the name. She was satisfied with the results, but being that I did not see myself, I cannot say whether or not I would feel the same.
