Does transplanted adipocytes get replaced after turnover? (27, male)

I'm considering facial fat grafting to deal with asymmetrical fat volumes on my face. This asymmetricity started after I had lipoma excision near my right nasolabial fold 10 years ago, and it seems to be more prominent as time goes by. My question is, what happens when transplanted adipocytes ends up with its lifespan under the condition that those are initially settled? I've seen doctors say it's permanent but in my knowledge the lifespan of a single adipocyte is about 10 years.
