My doctor is suggesting fat injections for a youthful look. What are your suggestions?

I had an endoscopic brow lift and an upper eyelid surgery 6 months ago and am not happy with the results. I feel like my eyes and my smile look very different now. My eyes look tired and their shape changed They look hollow and below the eyebrows there's loss of tone.My doctor is suggesting fat injection for a youthful look. I also feel like my cheeks are fuller now. Would the results change more through time? Should I look into reversing the operation? Or try fat injection? Suggestions?
