Should BodyTite only be performed by a board certified plastic surgeon?

you do not have to be a "board certified plastic surgeon" to perform bodytite.  you have to go to a physician who is trained and an expert. I am a dermatologist and done some of the most bodytite in the country.  I suggest you see an expert with skill and experience, one that is "board certified" of course.
 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.

Most times you are getting Bodytite and liposuction together for best results. The melted fat from Bodytite needs to be sucked out anyway so the two together does great.  But as far as Board certifications go, Board Certified Dermatologic Surgeons invented tumescent liposuction with the micro canulas and probably do a much better job at liposuction than plastic surgeons. Non-plastic surgeons get the 20 watt Bodytite unit and plastic surgeons get the 40 watt BodyTite Pro unit which is more powerful and faster. I have the advantage of being both a Plastic Surgeon and a Board Certified Dermatologic Surgeon so I can tell you from both sides of the fence who i would recommend. Using the Bodytite pro is better and faster but the Derm surgeons understand the skin and fat layer so much better that they tend to know just how far and how much zapping the skin can take for the tightening to  be beneficial without burning the skin or causing dimples.  Bodytite and Bodytite Pro both have the fail-safe devices built into them to prevent severe burns or trauma which Vaser and Renuvion/J plasma don't have. Both Board certified Derm Surgeons and Plastic surgeons can do a good job though.

I do not believe that it is a requirement to be a board certified plastic surgeon to do Bodytite. However, a board certified plastic surgeon will be able to offer other procedures for you to accomplish you cosmetic goal (tummy tuck, lipo, fat grafting...) if you are not an ideal candidate for bodytite or if bodytite does not give you the results you wanted. Good luck.
