Direct answer: Smoking reduces results and prolongs recovery. Nicotine constricts peripheral vessels, lowering skin blood flow and oxygen supply, which worsens the conditions for new collagen. Thermage, ultrasound lifting, thread lifting, microneedling and laser resurfacing all rely on the body producing collagen afterwards, so they deliver noticeably less in smokers. Healing is slower, bruising lasts longer, and infection and scarring risk rise. Common practice is to stop for at least two weeks beforehand, ideally four, and to keep going one to two weeks afterwards, with e-cigarettes and heated tobacco counted because they still contain nicotine.

Hours are Monday to Friday 10:00-19:00 and Saturday 10:00-17:00, and Chinese and English consultations can be arranged.
How exactly does nicotine affect the skin?
- Peripheral vasoconstriction: nicotine stimulates the sympathetic nervous system and narrows microvessels, cutting surface blood flow and leaving oxygen and nutrients short. This is the most direct mechanism
- Carbon monoxide reduces oxygen carriage: inhaled carbon monoxide binds haemoglobin, further reducing the oxygen available to tissue and making repair harder work
- Collagen is broken down faster: smoking raises matrix metalloproteinase activity, the enzyme family that degrades collagen, while fibroblast production of new collagen is suppressed, producing a double effect of more breakdown and less synthesis
- Immunity and infection risk: smokers have weaker wound defence and higher post-procedure infection rates, which matters for anything that creates a wound
- Long-term ageing markers: long-term smokers commonly show perioral lines, a sallow tone and reduced elasticity, themselves the result of collagen and elastin damage
Which treatments are affected most?
- Most affected, collagen-dependent: Thermage, ultrasound lifting, thread lifting, RF microneedling and laser resurfacing all depend on collagen being produced over the following months. Smokers have poorer conditions for that, so both the result and how long it lasts can fall short
- Most affected, any wound: any treatment leaving a wound or a deeper surface response heals more slowly in smokers, with higher scarring and infection risk
- Immediate results less affected, risk still up: the visible result of botulinum toxin and hyaluronic acid comes mainly from the product itself, so smoking changes the look less, but bruising, swelling and infection risk are still higher
- Body contouring: non-invasive options such as Onda also rely on metabolism and tissue response, so poorer circulation can mean slower recovery and slower visible change
- Injectable skin treatments: skin boosters and other injectables need good blood flow for the repair response, so redness and needle-point healing usually take longer in smokers
Do e-cigarettes, heated tobacco and nicotine replacement count?
- E-cigarettes and heated tobacco: both contain nicotine, and the vasoconstriction mechanism is the same, so they do not count as stopping. Some products carry additional irritation risk from thermal breakdown products
- Nicotine patches and gum: replacement therapy used to quit still contains nicotine and still affects blood vessels, though it avoids the other harmful products of combustion
- Truly nicotine-free: only that state removes the nicotine effect. Be honest at assessment about the actual form and frequency you use
- Second-hand smoke: long-term exposure affects circulation and skin condition too. The effect is smaller than active smoking but still worth mentioning
What should you do before and after?
- Before: stop for at least two weeks, ideally four. Vascular function and tissue oxygenation improve gradually, and even a short break produces measurable difference
- After: keep going for at least one to two weeks, and longer for collagen-stimulating treatments since results form over months
- If you cannot stop fully: tell the physician honestly so the treatment choice and aftercare intensity can be adjusted. That is safer than concealing it
- Alongside other factors: sleep, hydration and sun protection affect collagen production too, and quitting delivers its full benefit only when these improve together
How to choose a clinic that is honest about risk: three criteria
- Does intake cover smoking: a clinic that asks routinely is treating it as a variable that affects outcomes. One that never asks usually cannot explain why a result fell short either
- Does it explain the specific impact: a responsible physician explains what smoking does to the procedure you are actually having, not just that it is better not to smoke
- Is the factor revisited at review: if results fall short, whether the clinic goes back to lifestyle factors such as smoking and adjusts accordingly is a good test of how complete its assessment is
What actually happens at Rappoel
- Smoking history at intake: whether you smoke, the form used, whether cigarettes, e-cigarettes or heated tobacco, frequency and daily amount, plus nicotine replacement use and second-hand exposure
- Specific impact explained: a board-trained dermatologist explains what smoking means for the proposed treatment in terms of result, recovery and complication risk
- Timing advice: recommended smoke-free periods before and after are given according to treatment type, longer for collagen-stimulating procedures
- Baseline photography: photographs beforehand allow recovery and result to be compared objectively afterwards
- Manufacturer-certified products: treatments use certified products and threads with traceable batch numbers
- Closer follow-up: patients who continue to smoke are reviewed more often, watching healing speed, bruising resolution and signs of infection so anything unusual is caught early
Side effects and who should wait
- Expected differences: longer redness, more visible bruising and slower healing of needle points and wounds. These are predictable variations rather than abnormalities
- Signs to watch: delayed healing, persistent redness, pus, or discolouration at wound edges should prompt an earlier visit rather than self-observation
- Better to improve first: heavy daily smokers, those who also have diabetes or peripheral circulation problems, and anyone with a history of poor wound healing should improve conditions before assessment
- Specialist review: anyone with chronic respiratory or cardiovascular disease, or currently undergoing smoking cessation treatment, should have overall status confirmed first
Frequently asked questions
Q1: Does smoking really make Thermage or ultrasound less effective?
Yes, it reduces the result. These treatments work through collagen produced over the following months, and smoking lowers skin oxygen supply, suppresses fibroblast function and accelerates collagen breakdown, worsening the conditions for that production. Both the result and its duration can fall short of what a non-smoker achieves.
Q2: How long before treatment should I stop?
At least two weeks is the common recommendation, ideally four. Vascular function and tissue oxygenation improve gradually after nicotine stops, and even a short break produces measurable difference. Continue for one to two weeks afterwards, and longer for collagen-stimulating treatments.
Q3: Are e-cigarettes or heated tobacco less of a problem?
Not really. Both contain nicotine and constrict vessels through the same mechanism, so they do not count as stopping. Some products carry additional irritation risk from thermal breakdown products, and the actual form used should be stated honestly at assessment.
Q4: I use nicotine patches to quit. Does that still count?
Yes. Nicotine replacement still contains nicotine and still affects blood vessels, though it avoids the other harmful products of combustion. If the aim is to maximise the result, the endpoint is still a fully nicotine-free state.
Q5: Does smoking matter much for filler or botulinum toxin?
Less for the visible result, which comes mainly from the product itself, but bruising, swelling, recovery time and infection risk are all higher. In other words, the outcome looks similar but the process is harder.
Q6: How does Rappoel ask about smoking?
Intake covers whether you smoke, the form used, whether cigarettes, e-cigarettes or heated tobacco, frequency and daily amount, plus nicotine replacement and second-hand exposure. A dermatologist then explains the specific impact on the proposed treatment and the recommended adjustment period.
Q7: I cannot quit right now. Can I still be treated?
Yes, but say so honestly. The risk of concealing it is that the physician cannot adjust the treatment or the intensity of aftercare. Once informed, they can choose less affected options, tighten follow-up, and revisit this variable if results fall short.
Q8: Why does the clinic ask? Is it going to refuse me?
It is not a refusal. It is so the reasons a result may be reduced, and the difference in recovery, are explained in advance. A clinic that includes smoking in its assessment can usually also explain clearly what went wrong and adjust when results fall short.
Q9: How noticeable is the effect on wound healing?
Quite noticeable. Nicotine narrows microvessels and reduces tissue oxygen, and immune defence is weaker, so healing and bruise resolution both take longer while infection and scarring risk rise. This matters most for treatments that create a wound.
Q10: Where is Rappoel and how do I get there?
The clinic is at 77 Seocho-daero, Seocho-gu, Seoul, near Gangnam Station, roughly a five-minute walk from Exit 2. Hours are Monday to Friday 10:00-19:00 and Saturday 10:00-17:00, closed Sunday, with Chinese and English consultations available.
