I had lipo on my rib cage 2.5 months ago and it looks like I have track marks or stretch marks. Will they go away? (Photo)

Significant contour irregularities to three months after liposuction is somewhat unexpected. There appears to be some thermal damage to the skin and it's possible that these irregularities are the product of laser or ultrasonically assisted liposuction. It would be useful to know.

What kind of liposuction technique was used? Anyhow is quite likely that the identations dissapear, give them 6 months, and in contrary case a revisional procedure of conventional liposuction my reduce them or get rid of them.

This can happen to patients if there is too aggressive liposuction performed or an energy based device is used superficially (in my opinion).  I would suggest external radiofrequency device with massage like velashape or venus and considering topical lightening creams (although these are rarely helpful).  Typically time is the best option for this.  Best, Dr. Emer.

It's common to have some areas of hardness or contour irregularity after liposuction. Most of these will typically smooth out with time. Continue wearing your compression garment and follow up with your operating surgeon. If you still have areas of indentation of hyper pigmentation after 6 months, ask your surgeon how best to correct these issues. Good luck!

Your photos look like the tracks of the liposuction cannula.Notwithstanding that it is still relatively early in your recovery.Ask your surgeon about local massage +/- ultrasound.
