Should I Lose Weight Before a Facelift?

Part of the aging process is not only loose skin in the neck and jawline, but volume loss. As you lose weight, you will see changes in your face that equate to aging. Rather than regaining weight, you could consider re-volumization. There are many options including fillers, fat transfer and even cheek implants. I would recommend you talk to specialist in Facial Plastic Surgery to discuss your specific case.

Stable weight best for most cosmetic surgery including facelifts
In general  it is best to be at your stable long term weight to reduce the probability for revision surgery. It makes little or no sense to loose or gain weight for a surgical procedure including Facelift unless you can maintain that weight for many years or it is a relatively small amount (plus or minus 5 pounds). This is because if you lose fat that is supportting your facial skin it will tend to sag especially if you don't have good skin elasticisity (most facelift patients)

It would be prudent to be within 10-15% of your ideal bodyweight before any type of facial or body rejuvenation surgery as this will allow you to maximize your result.

Many patients ask me if they should lose weight before a facelift. If it's a matter of losing twenty pounds, it simply will not make any difference. Having the facelift performed in and of itself will make you look like you've lost weight. Losing an additional twenty pounds after the facelift should not cause it to sag. I say go for it now and enjoy the new you.

It is in any case desireble to loss all possible weight before any plastic surgery procedure but not everybody can do that.  When the patient get spable in the weight  loss  the surgery can be executed and the patient will be satified.  Also the disposition of the fat in the body is diferent in everybody and some patient even when they are not  obese the have deformities like doble chin than make them look hevier than what the BMI is  so this surgery will carrect that problem.
