The timing of a facelift with regard to weight loss is not really important. A facelift is designed to improve the jawline and neck. The excess fat that exists in the neck will be removed during the procedure and so it is not necessary to lose the weight first. Having said that, significant weight loss in the face can lead to aging of the cheeks and lower eyelids. This can be corrected with a facial fat transfer. Usually the timing of this is not that important as long as you are not losing large quantities of weight. I usually use 30-40 pounds as a rough guideline of enough weight to make a difference. As long as you don’t have that amount of weight or more to lose then I feel it is OK to proceed with a facelift or fat transfer.
