Microlipo to nasolabial fold and cheek?

I had a facial fat transfer 4 months ago and was injected in areas I did not want, including outside the nasolabial fold (instead of the piriform) and too low on high lateral cheek. My dr said we can always do microlipo to remove unwanted fat, but how safe and precise is this procedure? And can I get staged rounds of conservative microliposuction every 3 months?
