Different technique in different countries
I don't think the difference varies as much in different countries as it does from doctor to doctor.
One particular thing to be very cautious of it when assessing fat transfer pictures is the timing of when the pictures were taken.
Fat transfer requires at least six months before final results are seeing.
Pictures taken sooner than that will show results that can be very different than the final long-term outcome.
Since a substantial amount of fat will not survive and the fat that survives can be unpredictable early results can be deceptive.

Is there a difference between fat transfer techniques in United States and Korea?
After seeing results from Korea I agree that many surgeons in the US seem to be more conservative with the degree of change they accept. I try to match the patients wishes.
