How Long Should I Wait for a Second Liposuction Treatment?

I would wait about 3 months for the swelling to resolve before starting a Hidef liposuction revision that includes skin tightening, fibrous release, and microliposuction. Best, Dr. KaramanoukianLos Angeles

I would wait at least 6 months to allow the majority of the swelling to subside.  Consider a second opinion if you weren't satisfied with your first treatment. 

Because each patient heals differently and some can take a bit longer than others, I would recommend waiting 6-8 months before doing another procedure. That way you'll be better healed from surgery and also be able to determine better how much residual fat there is to remove. However, you may want to get a second opinion since your results should have been achieved with the first surgery.

Liposuction revision, also known as liposuction correction or liposhifting, is a cosmetic surgery that improves the results of a previous liposuction procedure. It can be performed on any area of the body that was previously treated, such as the abdomen, hips, thighs, arms, or neck. Some reasons for revision liposuction include: Asymmetry Too much or too little fat removal Sudden weight gain or loss Weight gain or aging after the procedure Skin irregularities, such as skin laxity, irregular bumps, keloids, or a wavy, rippled appearance Dimpling or lumpiness, which can be caused by small pockets of fat or scar tissue The procedure involves making small incisions in the targeted areas, and depending on the case, additional fat may be removed or reinserted. Some risks of liposuction revision include:InfectionBleedingAdverse reactions to anesthesiaScarringIrregularitiesPlacing too much or too little fatSwellingBruising A consultation with a skilled plastic surgeon can determine if liposuction revision is appropriate.

You have given too little information. If you want the same area treated again I would say wait at least 6 months, if a separate area  then  even a month or two would be OK if there were no complications.

Generally this is  a body contouring procedure and not a wight loss program.

You should consult a Board Certified Plastic Surgeon to see what your options are.
