Arm fat rolls - would liposuction and skin tightening help?

Hello,
Great question. Thank you for your pictures. Unfortunately, they do not adequately show your arms, there must have been an issue with uploading. Please visit a board certified plastic surgeon for a detail surgical plan to achieve your desired results. 

From your front view photograph, it appears your breasts are low on the chest wall, pulling down and it may be distorting the axillary skin.  It is possible that you would benefit from a breast lift but your photographs are very limited and I cannot tell for sure.  Certainly, if you have had massive weight loss this would be a possible cause.  Skin tightening is ineffective and liposuction may be possible, but more information is needed.Best Wishes,Gary Horndeski, M.D.

liposuction plus internal heating (j plasma/renuvion is best here) will give you improvement based on your photos you may still have some sagging , the best improvement would be a mini or full Brachioplasty with liposuction and heating.
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.
