Am I botched? I have a deep line on my lower back after liposuction performed in May (Photo)

From the photograph provided it's impossible to comment specifically. If there is redundant skin that is gathering up along the crease the only treatment would be surgical excision. Physical examination would be required to establish the diagnosis.

I have to see before and after photos to really know what this may be from. Some people have loose skin that often does this "indentation" or "fold" after the fat is removed if VASER or another energy device like ThermiRF or laser isn't used.  Also, sometimes the skin really needs to be removed at the same time. I suggest posting clear before and after photos and speaking to your board certified dermatologist or plastic surgeon who performed the procedure if you are concerned.  Best, Dr. Emer.

It is very likely due to the liposuction cannula grazing or poking the underneath part of the skin called the dermis causing fibrosis and uneven retraction of the skin. It happens to also be occurring at a naturally fibrotic area at the bottom of where the back settles making it worse. Well done revision liposuction to release the scar wth fat transfer and possible blending liposuction above and below should improve it.
