Smoking is the single largest controllable risk factor in plastic surgery. It slows wound healing, raises infection rates, and in operations that move skin around it can cause tissue to die. Every surgeon says so, and every patient has heard it. What most pages do not tell you is what to actually do if you smoke, how long before surgery matters, and what happens if you light up afterwards. This page does.
A meaningful share of my patients smoke. I do not turn them away, and I do not pretend the risk is smaller than it is. What follows is what I tell them in consultation.
What Smoking Does to a Healing Wound
Three things happen at once, and each of them matters for surgery.
Less oxygen reaches the tissue. Nicotine narrows the small blood vessels, and carbon monoxide from the smoke displaces oxygen in the blood. Healing tissue is starved exactly when it needs oxygen most.
The immune response weakens. Smokers are more prone to wound infection, and infections in a surgical wound can undo a good result.
Collagen production drops. Wounds close more slowly, are more likely to reopen, and tend to leave thicker, more visible scars.
The consequences range from delayed healing and wider scars to wound breakdown, infection, and in the worst cases skin necrosis, where part of the skin edge dies and has to be revised. Smokers also carry a higher risk of blood clots after surgery.
Which Operations Are Most Affected
Not all procedures carry the same risk. The operations that lift and reposition skin, where the skin edge has to survive on a reduced blood supply for a while, are the sensitive ones:
- Tummy tuck and body lift
- Breast lift and breast reduction
- Facelift and neck lift
- Arm and thigh lifts after weight loss
Liposuction, rhinoplasty and eyelid surgery are less sensitive to smoking, though healing is still slower and scars still worse. If you are planning any of the operations in the first list, what you read below matters more.
How Long Before Surgery Should You Stop?
The honest answer from the research is: the longer the better, and every week counts.
Pooled data from randomised trials shows that each additional week without smoking before surgery increases the protective effect by roughly a fifth. Four weeks is the point at which the benefit becomes clearly significant, which is why four weeks is the figure most guidelines quote. At four weeks the risk of wound complications is roughly a third lower than in someone still smoking. At eight weeks the benefit is larger again.
But this is not a threshold where anything less is worthless:
- Two weeks already produces a measurable drop in complications.
- A few days before surgery is still worth it, because carbon monoxide leaves the blood within a day or two and tissue oxygen levels start to recover.
- The old idea that stopping shortly before surgery is worse than not stopping at all has not held up in the research. It is not a reason to keep smoking.
The realistic version: I ask every patient for four weeks. I know that most smokers will not manage it, and I would rather know that than be told what I want to hear. If four weeks is not going to happen, aim for two. If two is not going to happen, at least stop in the last few days and do not smoke on the morning of surgery. Whatever you manage, tell me the truth, because I plan the operation around it.
If You Cannot Stop: What Actually Helps
Cut down. The damage is dose related. Half the cigarettes is not as good as none, but it is a good deal better than the full number.
Nicotine patches or gum are acceptable. Nicotine itself is not harmless, but the research is fairly consistent that replacement therapy is far less damaging to healing than continuing to smoke, largely because it removes the carbon monoxide and the thousands of other combustion products. Replacement therapy also roughly doubles the chance of actually staying off cigarettes. In practice I have had very few patients who needed it, but if it helps you stop, use it.
Vaping is not a safe substitute. Electronic cigarette aerosol has been shown to damage the small blood vessels in much the same way as smoke. Switching to a vape before surgery is not the same as stopping.
Do not hide it. Patients under-report smoking; every surgeon knows this. Nothing on this page works if I am planning a facelift for a non-smoker and operating on a smoker.
I Do Not Cancel Surgery Because a Patient Smokes
Some surgeons refuse to operate on smokers, or test for nicotine on the morning of surgery and cancel if it is positive. I understand the reasoning, but it is not my approach.
If a patient smokes, we talk about it honestly, I ask them to reduce as much as they can before and after, and I adjust the plan where necessary. For the operations most sensitive to smoking, that can mean a more conservative technique, closer follow-up, and in selected cases a course of hyperbaric oxygen therapy, which delivers oxygen to the healing tissue at higher pressure and is one of the few interventions that directly counters what smoking takes away.
You will not be turned away. But you will be told the risk clearly, and you will be asked to do your part.
Smoking After Surgery: When Can You Start Again?
This is the question people actually search for, and the one most pages skip.
The first two weeks after surgery are the critical period. This is when the wound is closing, the blood supply to the skin edges is at its weakest, and the risk of the skin edge breaking down is highest. The literature recommends staying off cigarettes for up to four weeks after surgery. Every day you manage in the first two weeks matters more than any day after.
The realistic version, again: many patients do not manage even the first week, and I know it. So the advice is arranged by priority:
- Days one to fourteen: this is where I ask for real effort. If you smoke in this window, at least keep it to as few cigarettes as possible. This is not the moment to go back to your usual number.
- Weeks three and four: still healing, still better without. If you have started again, keep it low.
- After a month: the wound is closed and the immediate danger has passed. Smoking will still make your scars mature more slowly and look worse for longer, but the risk of losing tissue is behind you.
For the operations in the sensitive list above, particularly tummy tuck and facelift, the first two weeks are not negotiable in my view. If you know you cannot stay off cigarettes for that long, tell me before the operation, not after. If you want a day by day plan built around your own surgery date, the recovery planner will generate one.
Frequently Asked Questions
How long before surgery should you stop smoking?
Ideally four weeks; every week counts and two weeks already helps. Even stopping in the last few days is better than not stopping. Do not smoke on the morning of surgery.
Can you smoke after surgery?
You should not for at least two weeks, ideally four. The first two weeks are when the wound is most vulnerable to breaking down. If you cannot stop completely, keep it to as few cigarettes as possible in that window.
Will my surgeon cancel the operation if I smoke?
Some will. I do not. I ask you to reduce before and after, plan the operation with the risk in mind, and in selected cases add hyperbaric oxygen therapy.
Are nicotine patches or gum allowed before surgery?
Yes. Nicotine replacement is not risk free, but it is far less harmful to healing than smoking and it makes it more likely you will actually stay off cigarettes.
Is vaping better than smoking before surgery?
No. Electronic cigarette aerosol damages the small blood vessels in much the same way as smoke. Vaping is not a substitute for stopping.
Which operations are most affected by smoking?
Tummy tuck, body lift, breast lift and reduction, facelift and neck lift, and arm and thigh lifts. Any operation that lifts and repositions skin.
What is hyperbaric oxygen therapy and why is it recommended for smokers?
It is a course of breathing pure oxygen in a pressurised chamber, which raises the oxygen reaching the healing tissue. Smoking reduces tissue oxygen; hyperbaric oxygen directly counters that. I recommend it in selected higher risk cases.
