I'm only 32 but I've lost a lot of weight in the last year and I've always had slightly sunken cheeks - the result being that I look kind of haggard and tired all the time in the eye/cheekbone region.
I'm so, so glad I finally decided to get this done - the results were instant and really natural - it looks just like the face I had maybe 5-10 years ago - my eye/cheekbone area looks perky and plump but in a very youthful, real way - like I just had a great night of sleep. And perking my cheeks up also softened my naso-labial lines because my cheeks are fuller.
I just had it done yesterday. No bruising, no swelling, no bumps, and thanks to numbing cream plus the lidocaine in it, it was barely painful at all.
I really can't think of a con, it's an awesome treatment.
