What causes lipo burns?

Excellent question! Liposuction burns are from heat generated liposuction equipment such as lasers or radio wave technology and cannulas. Such energy generated cannulas first burn or melt the fat, and then the fat must be liposuction. These procedures take two steps to remove the fat and then add an additional list of complications, such as pigmentation changes of the skin and even burning the skin.
My preference is the Tickle Liposuction technology, which is infrasonic and thus generates no heat, or traditional liposuction. These procedures are faster and safer in my opinion after having performed liposuction procedures since 1982.
I hope this answers your very interesting question for you.
