Although most surgeons will differ on exactly how long before surgery to stop cigarette smoking, the vast majority of surgeons consider it to be an extremely important exercise prior to facelift surgery. The reason for this is that the nicotine in tobacco causes blood vessels to constrict, a process that can diminish the blood flow to thin, gentle flaps such as those elevated during a facelift. Most surgeons agree that a minimum of two weeks is ideal; despite this, there are surgeons who will prefer/request that smoking be ceased for 4 weeks, and others for an even longer period of time. Personally, although 14 days is my usual recommendation, I don't believe that 4 days will necessarily translate into a high risk. By far, the most important aspect is to NOT smoke during the post-operative period. Having patients stop smoking 2 weeks is not only beneficial for the body/skin during the healing phase, but it also demonstrates to the surgeon that the patient is ready for the procedure and will be able to continue to abstain from smoking post-operatively. Please discuss this with your surgeon as his/her preferences may differ. Also, please be sure that you are not taking any nicotine replacement products, such as gum, patches, or e-cigarettes, all of which contain nicotine. Best of luck :)!
