I had lipo on my inner knees to my inner upper thighs, waist, and back. I just noticed small dark circles on both sides of my lower butt is tis from lipo also done on the back of my legs or could it be from fat transfer that was placed in my butt. There are no other scars on the back of my legs I'm curious to what this can be. Due to disastrous outcome from the tummy tuck that was also done at that time, i am no longer seeking his medical help. And yes, this was a board certified Doctor in US
