Persistent scarring after nano fat transfer below eyes, is it permanent? (photo)

I had a procedure called nano fat cell transfer below my eyes+regular fat transfer to my cheeks. I developed bruising below the eye area after the procedure. Doc reassured me that it will resolve within 2 weeks&did medlite laser.The fat transfer on my face also seem to be not equal( 9 cc of fat on each cheek) He told me that the take of fat transfer alone is only 30%.Concerns; 1) the darkening under my eyes, permanent? 3) the fat transfer to cheek,how long will it take to see the final outcome?
