My plastic surgeon did chin lipo 4 years ago and I was happy with results for 2 years. These past 2 years the fat has returned or at least it looks like fat to me...is this really possible to gain this much fat in this area after initial liposuction? Or is it a "possible reaction to the lipo laser" that was used during my lipo like my Dr says it is? He says I 'll never lose this chin fat even though I've lost 20 lbs this year. He will do it again for "free" If I add on more lipo to another area.
