Smoking has been shown in numerous scientific publications to dramatically affect the healing of facial skin and soft tissues post-operatively. At the minimum, you should stop smoking completely 2 weeks prior and for 2 weeks after a facelift. If you absolutely cannot stop smoking, hyperbaric oxygen may be utilized before and after the facelift to reduce but not eliminate the chances of wound healing problems. The endoscopic technique can be adjusted so that the skin layer is not disturbed, thereby preserving its blood supply while your surgeon works on deeper layers. However, this is at the surgeon's discretion. It behooves you, to be honest about your smoking habits with your surgeon.
