I am a 21 year old, 5'4", 300 pound female. I was wondering if liposuction was possible for me? (Photo)

Dear SelfLove0786,
liposuction is not a weight loss surgery. Generally speaking, you want to reach your goal weight before you consider a surgery, otherwise your results will be suboptimal if you continue to lose weight after the surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

you need as much weight loss as possible before considering liposuction or skin removal. I suggest bariatric surgery and/or hormonal/peptide therapy (see link).

my whole practice is doing lipoabdominoplasty, or at least liposuction with internal heating (which is not the gold standard for skin tightening with body contouring).

the smaller you are before liposuction the more contouring you can get from the procedure. most of my liposuction patients get pre and post surgical optimization with hormonal therapy (see link to help boost their weight loss before surgery and help them heal after).

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.
