Dr Lam - at what stage do you (using your technique - I appreciate you can't answer for any other practitioner) judge a patient's "final result" following fat transfer? What I mean is, when do you tell your patients "this is it, the fat/volume that's stayed in your face is permanent [subject to regular facial aging, etc]". Is it around a year? 6 months? I know you acknowledge there's a dip about the 3 month stage.
