The problem with fat melting injections is that since they're so new, they are only recommend for the double chin area and not jawline/cheek area. Have you considered facial liposuction, such as traditional lipo or acculift? You may also want to consider buccal fat removal, but I have heard mixed reviews about this - many drs say it can cause your face to look overly gaunt when older.
One PFer did power V at TLPS and had a great result -

I consulted with TLPS on kk and I thought their price was a little excessive for what they were offering though.
I also consulted with Fresh ps and visited their clinic because I thought this before/after was very impressive:

However, the consultants were very rude and pushy and wasted my time by talking about procedures that apparently I 'needed', despite telling them repeatedly I had no interest. On kk I had requested to see the dr, they agreed on a date, and then the day before that date they said the dr was not available. The date was then moved to a week later, and then when I arrived for my consult I spent ages with the consultant, thinking I would see the dr after and then they told me the dr could not see me.
Regardless, they do have very good B/As.
