Can you be too thin for hi def lipo? I have a BMI of 21.5. I am 5 ft tall and weigh 110 pounds

Using the Vaser ultrasound system and maybe employing a power assisted device with it can give a beautiful more athletic look, so being smaller with less fat is a bonus. In person evaluations are the best to look at skin turgor, and fat distribution. See a provider that has experience and get a good evaluation. Hope this helps. JB

Thank you for your question, You need a formal evaluation by an expert in body shaping and contouring to determine what is best. The best in body contouring not only removes fat with energy devices like VASER ultrasound but also internally heats the skin with radiofrequency devices such as Renuvion (J-Plasma), InMode BodyTite, and ThermiRF to heat the undersurface of the skin and tighten it at the same time as fat removal. These combinations are called 4D HI-DEF VASER Liposuction and can only be done by a well-trained body contouring specialist. At the same time, fat should be harvested and purified, with PRP and stem cells added, and then injected into muscles, indentations and cellulite to get body shaping and contouring. For a Brazilian butt lift (BBL), we inject the fat into 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 a combination of Cellfina, 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: tummy tuck/abdominoplasty for lower abdominal skin; breast lift for excess breast skin; and/or a brachioplasty for loose arm skin.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. See an expert. Best, Dr. Emer.

Hi there,
not really, it depends on your whole body composition and structure.
Every individual has their fat distribution differently.
Best would be to go see a qualified Hi Def surgeon who can assess you and discuss the options.

No, you can still get high definition VASER liposuction. Considering your BMI you likely want to focus more on contouring and definition than comprehensive fat removal. High definition VASER liposuction is the most efficient technique for body etching. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.

some people can get great liposuction results when it comes to getting definition. You should not expect to see significant contour changes in regards to overall body proportions since you don’t have enough fat to make changes that way. For example your clothes will fit the same but your muscle wall of your abdomen could look better. Personally I would approach high definition to work with a great deal of caution. This is generally based on purposely giving people an abnormal fat distribution with the Intention of trying to make fat look like muscle. To me the results look like what they are. An artificial attempt to make fat look like muscle. It’s definitely a much better procedure for thin people then people With even modest amounts of body fat. This procedure is extremely unforgiving for technical errors and any results obtained can generally never be reversed. If those lines are etched incorrectly you will live with them for the rest of your life. Also, if you gain weight in the future then the results can look ridiculous. Personally I prefer a more natural thin even fat distribution that is natural and mimics extreme weight loss.For sure this should only be done by those who Have a lot of experience. Preferably many thousands of cases under their belt. This is not a good procedure to have done by someone who bought a VASER in the last 12 months and just took the body contouring course by Alfredo Hoyos.Best, Mats Hagstrom MD
