Is J Plasma effective with lipo on thighs? My thighs aren't very flabby. I'm having lipo from my thighs for fat transfer (BBL)

Yes J Plasma (Renuvion) is fantastic for the thighs. I almost always combine thigh liposuction with J Plasma. The skin tightening effect of J Plasma allows me to take out more fat than if J plasma wasn't used, and also tightens your thighs as well.

you have to be a good candidate for it to work on the thighs, often thighs need thigh lift + liposuction at same time, see link.

You need a formal evaluation by an expert in body shaping and contouring to determine what is best.  Traditional liposuction awake and smart liposuction are old methods and do very poorly for tightening skin or significant skin tightening or contouring.  Small problem areas can be improved slightly by these methods.  The best in body contouring not only removes fat with energy devices like VASER ultrasound but also internally heat the skin with radio-frequency devices such as J PLASMA/RENUVION, InMode BodyTite, ThermiRF to heat the under surface of the skin and tighten it at the same time as fat removal. These combinations are called 4D HIDEF VASER contouring and can only be done by a well . trained body contouring specialist. At the same time fat should be harvested, PRP and stem cells added and injected into muscles or indentations/cellulite to get body shaping and contouring.  This is known as a Brazilian butt lift when you inject the fat to the buttock for contouring and lifting, but fat can also be used in areas such as the chest/breast, arms/shoulders, calves and face.  Cellulite should also be treated with cellfina, sculptra, subcision and/or fillers such as bellafill, renuva synthetic fat, or sculptra.  If skin is very loose before surgery then it will need to be removed such as lower abdominal skin (tummy tuck/abdominoplasty), breast skin (breast lift), arm skin (brachioplasty).  Overall you need a full assessment, but simple liposuction alone will not tighten skin and needs a combination of various methods -- fat removal, skin tightening, defining, fat grafting, skin removal -- to get the best in body contouring and body sculpting.  Dr. Emer.

The J-Plasma, now called Renuvion, is effective for tightening the skin on the thighs and just about anywhere. It is usually combined with liposuction, which removes the fat but doesn't tighten the skin very well. I suggest finding someone who uses the Renuvion for a consultation to see if you are a candidate. The Renuvion is the latest technology.
Thank you for your question, and best of luck.
