Will this treatment smooth out lumpy lipo on front of thighs?

Thank you for your question, non surgical options give only mild improvement compared to surgical lifting. If there is a lot of skin laxity, a thigh lifting procedure performed at the same time as hi definition liposuction like VASER HI DEF would give the most improvement. Other options for skin tightening would be a combination approach with vanquish, venus legacy, exilis, celllutone/Zwave. I recommend getting a formal evaluation with a high definition physique expert. Best, Dr. Emer

I use Trusculpt Id to correct liposuction irregularities all over the body. The treatment is very customized so a physical examination is needed to make sure you are a good candidate. If the lumps are excess fat in certain areas then I have seen great success. 

As TruSculpt uses radio frequency that radiates heat evenly over an area that both destroys fat cells and tightens the skin, it could smooth out some of the bumpiness you describe.  Because the process uses heat that uniformly radiates beyond the applicators the effects are feathered in for an even result.  That being said, there is no substitute for an in-person consultation to determine if TruSculpt is the best option to achieve your treatment goals. 

Thank you for your question, 
truSculpt iD can be very effective at smoothing out targeted areas. I would recommend  an in-person consult to rule out scar tissue vs irregular fat distribution. This procedure can be done in 15 mins, is relativity painless, and has no downtime.

Trusculpt3D might help to improve the "lumps", but quite possible you have scar tissue that will not be removed or changed by the procedure. You do not have warranties that the lumps will resolve completely.
