Smoking cigarettes during the early post-op period will not be good for survival of the fat which relies on good oxygenated blood to survive.
Although we would like all of our patients to refrain from smoking for a month or so before surgery and a month or so after, there are some procedures where it really is critical. These include facelifts, tummy tucks, and fat injections. The survival of that fat is very precarious in the first few weeks after surgery, requiring the body's blood supply to nourish the delicate fat cells. Even smoking one cigarette (or breathing second hand smoke) can cause a measurable decrease in capillary bloodflow. Stop smoking immediately, hopefully you'll get lucky with little or no damage done.
Thank you for your question, after surgery it's best if you wait at least a month o two after the surgery for you to resume smoking, since smoking can lead to complications such as fat necrosis, lack of oxygen through fat cells, and loosing fat cells as well.
Smoking interferes with the healing, even one cigarette will interfere, If you develop a complication or the fat does not take, then do not blame your plastic surgeon
Please tell your surgeon that you've smoked if you suffer from a complication, such as infection or delayed wound recovery.
