For optimal healing after an upper and lower blepharoplasty, I would recommend no cigarettes for one month before the surgery until 2 weeks after the surgery. Each surgeon will have their own preferences in regards to smoking in relation to cosmetic surgery though.
Thanks so much for your question. The good news about eyelid surgery is that it's a very vascularized area of the body. Although it's best not to smoke when having elective surgery, it's an area that would be less affected by smoking than other areas. Wound healing should still be fine in smokers. I would encourage you to stop smoking for a short period of time before and after your surgery, but I would still offer you surgery for this type of a procedure either way. Hope this helps.
