After 3 procedures I have disproportionate thighs. Is there any hope to fix it?

I can see why this is a concern for you. Without physical examination it's impossible to conclude what is specifically wrong. Sometimes inadequate liposuction may require a revision to make the results uniform. If the problem is excess skin this is another situation altogether. In My opinion there is no benefit to skin tightening technology. Maybe time to get another opinion.

Lipo sculpture was made for this kind of problem, your torso looks great and your skin tone seems wonderful. See a board certified plastic surgeon who does a ton of liposuction and ask specific questions. How many liposuction have you done on women who look like me last year? Don't settle for vague answers and ask to talk to a patient who looked like you. All surgeries carry risks and disappointment is key. Good luck.
