If I lose weight after fat transfer to lips will my lips shrink back?

Good question! While you may lose a small bit a volume right after procedure, weight loss should not affect your result.

Most surgeons with a lot of experience in fat grafting, including myself, agree that the transplanted fat does not respond to changes in weight as it would if left in its natural location. So if you were to undergo extreme weight loss you might observe a slight decrease in volume but you would still maintain a noticeable improvement over your preoperative appearance.

Fat certainly responds to weight changes , but even if its shrinks you will still keep the proportion , since all the fat from your body shrinks at the same time . so , in relation to the rest of your face , your lips should still look good Best wsihes
