Will weight gain affect fat transfer?

It's not uncommon to observe changes in facial contours following a fat transfer procedure, particularly when there are significant weight fluctuations. Gaining 15 pounds over the past two months could indeed be contributing to the increased fullness in your upper cheeks and midface.

Fat cells, including those that have been transferred, can increase in size when you gain weight. This process, known as hypertrophy, can lead to a more pronounced appearance in areas where the fat transfer was performed. Consequently, the changes you've noticed, such as the enhanced fullness and the alterations around your mouth, could be related to this weight gain.

Regarding your concerns about weight loss impacting your facial appearance: losing weight will likely reduce the size of the transferred fat cells, thereby decreasing the fullness in your face. If this weight loss is gradual and controlled, it should not 'ruin' your face. In fact, it may help in achieving a more balanced and natural look, aligning with the initial goals of your facelift and fat transfer procedures.

However, every individual's response to weight fluctuations can vary. It's important to approach weight loss in a healthy and steady manner, and to monitor the changes in your facial appearance as you progress. If you have concerns or notice significant changes during this process, I recommend scheduling a follow-up consultation with your surgeon. He/she could assess your current situation and discuss any additional treatments or adjustments that might be necessary to maintain your desired aesthetic outcome.
