How to get rid of stomach dent from liposuction? (Photo)

I specialize in fixing Liposuction defects. it can be made better. its a very common site for the defects to occur after Liposuction and I have fixed this multiple times. you can look at some of my B&A pics on my profile on RealSelf and also on IG (@drmisbahkhan6). there are several videos on my YouTube channel where I speak about how I fix defects post-liposuction. the link to my website is provided below. email me please if I can be of help

I would do a revisiobn procedure and consider fat gafting with or without internal heating or skinremoval based on individual assessment. 
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.

Dear chinc,
I would have to examine you but it appears that this is a contour irregularity after liposuction.  This happens often when areas the undergo liposuction are not feathered appropriately. The good news is that it can be fixed and I have done so with good results before. 
While there is always a chance for contour irregularities with liposuction, someone who takes their time and uses the appropriate sized cannulas should give you a superb result.I have all my patients wear compression garments and I use multiple sized cannulas to feather out the result.
