6 days post op, I got a burn or bruising after Brazilian Butt Lift and Liposuction. Will this mark eventually go away? (photos)

A bruise will heal.  A burn will likely leave a mark.   What type of liposuction did your surgeon use?  Laser or Ultrasound?  If yes then this could be  a burn.At this stage all you can do is care for the wound and allow your body to heal

Thank you for your question and for your photo. Bruising and swelling is normal and will eventually start going down. If any pain or any type of infection starts to persist, I would advise you to follow up with your surgeon.

Hello dear!!
Thanks for the question and provided information as well.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation, discomfort, bruising and irregularities are normal.
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)

It is always to properly appreciate from only photos, but if it is only a bruise, then it will dissipate.  It does not appear to be a burn, judging by photos only, since there isn't any blistering or skin slough.  It may be a collection of blood under the skin (hematoma) or an area of necrosis.  If it is necrosis, then one has to allow for the time to elapse to evaluate further. Keep in close contact with your surgeon.
