The final suture is not the end of an operation. It is the moment the biology takes over, and for the next two weeks the outcome of a technically flawless procedure rests substantially in the patient’s hands. In Dubai I have watched excellent surgery undermined by well-intentioned aftercare, and it is almost never neglect that does the damage.
It is diligence, misapplied. The patient who scrubs an incision with hydrogen peroxide, who paints it with iodine, who checks it four times a day and lifts the scab to see how it is doing — that patient is working hard against her own healing. This article explains why, and what to do instead. It reflects what I tell every patient recovering from surgery in Dubai, and it concerns the daily care of the incision itself: how to clean it, whether to cover it, and when to leave it entirely alone.
Key takeaways: caring for an incision
- Healing is done by fibroblasts and keratinocytes — protect them.
- Common antiseptics are toxic to those same cells.
- Sterile saline or mild soap and water is nearly always enough.
- A wound kept slightly moist resurfaces faster than a dry crust.
- The commonest error is doing too much, not too little.
- Spreading redness, cloudy drainage, or rising pain mean call, don’t treat.
A note on scope: this article is about the incision in front of you and what you put on it. What your body is doing beneath the surface week by week is covered in my article on the first 30 days of recovery, and what actually determines the quality of the final scar — which is decided long before you go home — in my article on scar placement and closure technique.
Who is actually doing the healing
Two cell types close a surgical wound. Fibroblasts arrive to lay down the collagen that will give the repair its strength. Keratinocytes migrate across the raw surface from both edges until they meet and seal it. Everything that matters in the first fortnight depends on these two populations staying alive and moving.
Hold that in mind, because it reframes every decision that follows. The question is never “what will kill the most bacteria?” It is “what will kill bacteria without killing the cells I need?” Those are very different questions, and the honest answer to the second is uncomfortable for anyone who grew up with a brown bottle of antiseptic in the bathroom cupboard.
How the choice of cleanser affects the cells that close a surgical wound, by Dr. Nazmi Baycin, Dubai.
The antiseptic paradox
Hydrogen peroxide foams satisfyingly on contact and feels like it is working. Povidone-iodine stains the skin an authoritative brown. Both are genuinely effective at killing bacteria. Both are also, at the concentrations people reach for at home, effective at killing fibroblasts and keratinocytes.
A study indexing twenty skin and wound cleansers for their toxicity to human fibroblasts and keratinocytes placed saline among the least toxic agents it tested, and hydrogen peroxide and ten per cent povidone among the most toxic. A later study of six commonly used wound antiseptics found that all of them significantly reduced fibroblast viability, and that three were so cytotoxic the researchers could not even measure how the wound closed afterward.
I want to be precise rather than alarmist. This toxicity depends on concentration and on how long the agent stays in contact; dilute antiseptics have a genuine and important role, particularly in contaminated or chronic wounds, and antiseptic skin preparation before surgery is essential. Both of these are laboratory studies of cells in culture rather than trials in patients, which is a real limitation. What the evidence does not support is pouring a full-strength antiseptic onto a clean, closed surgical incision that is healing normally. There, you are attacking bacteria that are not the problem, with a weapon that harms the cells that are the solution.
What to use instead
The answer is almost disappointingly plain. For a clean, closed incision, sterile saline or lukewarm water with a mild, plain soap is sufficient. The technique matters more than the agent:
- Wash your hands first — the single most useful thing you will do.
- Dab, never scrub. You are lifting away crust and exudate, not polishing.
- Pat dry with clean gauze, rather than rubbing with a towel.
- Apply only a thin film of whatever ointment I have prescribed.
- Do not lift the scab to inspect what is beneath it.
On ointment, more is emphatically not better. A thick layer traps moisture against the skin until it softens and macerates, which weakens the edges you are trying to knit together. A thin film is what is wanted.
| Decision | Instinct | Better | Why |
|---|---|---|---|
| Cleanser | Something strong | Saline or mild soap | Strength harms repair cells |
| Technique | Scrub it clean | Dab gently | Friction tears new surface |
| Ointment | Apply generously | A thin film | Excess macerates the edges |
| Frequency | Check often | Observe, don’t disturb | Handling reintroduces risk |
Moisture, dressings, and the myth of drying it out
Many patients believe a wound should be allowed to dry out and form a hard crust. The opposite is closer to the truth. Keratinocytes migrate more readily across a surface that is slightly moist than one that has dried into a rigid scab, which they must then burrow beneath.
This is why the dressing I choose is not passive gauze but a considered environment — often semi-occlusive or silicone-backed — intended to manage exudate while keeping the surface from desiccating. Moist is not the same as wet: a wound sitting in fluid will macerate. On showering, I give patients specific instructions rather than a blanket rule, because it depends on the dressing used and the procedure performed. Ask your own surgeon rather than assuming.
The discipline of doing nothing
If I could give a single instruction it would be this: observe, but do not disturb. The most conscientious patients are often the ones who interfere most. Every unnecessary inspection, every wipe, every reapplication is an opportunity to introduce organisms and to shear the fragile new surface that has formed since yesterday.
Restraint is not passivity. You are watching carefully — you are simply not intervening. This is the hardest instruction I give patients in Dubai, and the one that most reliably improves their healing. Nutrition supports this quiet work from within: adequate protein gives the fibroblasts their raw material, and hydration keeps the tissue supple. Broader preparation of the body before surgery, which pays dividends throughout healing, is covered in my guide to preparing for surgery, and the psychological side of recovery in my article on preparing your mind.
When to stop reading and call
Restraint has a limit, and knowing where it lies is part of the same discipline. Some findings are not for you to manage at home, and I would always rather see a patient unnecessarily than late.
Call your surgeon if redness spreads outward rather than fading, if drainage turns cloudy, discolored, or develops an odor, if pain increases after it had begun to settle, if you develop a fever, or if any part of the incision line separates. None of these is an occasion for stronger antiseptic. They are occasions for a professional to look at the wound.
A partnership, not a set of chores
I place the sutures; you steward what happens next. That stewardship turns out to consist mostly of gentleness and restraint rather than vigorous effort, which is a difficult thing to ask of people who want badly to help their own recovery.
But the biology asks for very little. Keep it clean with the mildest thing that works, keep it protected, keep your hands off it, eat and drink well, and call me when something genuinely changes. That is the whole of it, and it is the approach I ask of every patient having cosmetic surgery in Dubai under my care.
FAQs about wound care after plastic surgery in Dubai
-
Why should I not clean my incision with hydrogen peroxide?
Because it does not distinguish between bacteria and your own cells. Hydrogen peroxide kills fibroblasts and keratinocytes, the two cell types that are actually closing your wound. When researchers indexed wound cleansers for toxicity to those cells, hydrogen peroxide was among the most toxic agents tested, while plain saline was among the least. So on a clean, closed incision it works against you. It feels effective because it foams, but that sensation is not evidence of anything useful.
-
Is iodine bad for wounds?
I want to be precise here rather than alarmist. Concentration and contact time are what matter. Dilute antiseptics have a genuine role, particularly in contaminated or chronic wounds, and antiseptic skin preparation before surgery is essential. What the evidence does not support is applying a full-strength antiseptic to a clean surgical incision that is healing normally. So the objection is not to iodine as such. It is to using a strong agent where a mild one would do, and harming the repair cells for no benefit.
-
What should I actually clean my incision with?
Sterile saline, or lukewarm water with a mild, plain soap. That is genuinely sufficient for a clean, closed incision. The technique matters more than the agent. Wash your hands first, dab rather than scrub, pat dry with clean gauze, and apply only a thin film of any ointment I have prescribed. So resist the urge to reach for something stronger. The mildest thing that works is the correct thing, and saline was among the least toxic agents in the study that indexed these cleansers.
-
Should I let the wound dry out and scab over?
No, and this is a widespread misunderstanding. Keratinocytes migrate more readily across a surface that is slightly moist than across one that has hardened into a rigid scab, which they then have to burrow beneath. That is why a modern dressing is a considered environment rather than passive gauze, designed to manage fluid while keeping the surface from drying out. So aim for moist, not wet. A wound sitting in fluid will macerate, and a wound baked dry will heal more slowly. The dressing plan I give you is calibrated between those two.
-
Can I shower after surgery?
It depends on the dressing used and the procedure performed, so I give patients specific instructions rather than a blanket rule. I would be cautious of general advice you read online, in either direction. What is safe after one operation with one type of dressing may not be safe after another. So ask your own surgeon, and follow what they tell you rather than what a website tells you. That is one of the few genuinely procedure-specific parts of wound care.
-
Why does more ointment make things worse?
Because a thick layer traps moisture against the skin until it softens and macerates. Macerated edges are weak edges, and they are precisely the tissue you are asking to knit together. A thin film achieves everything a thick one does, without waterlogging the surface. So more is not better here. It is one of the clearest examples of a well-meant effort producing exactly the opposite of what was intended.
-
How often should I check my incision?
Far less often than most patients want to. Observe, but do not disturb. Every unnecessary inspection, wipe, or reapplication is a chance to introduce organisms and to shear the fragile new surface formed since yesterday. Lifting a scab to see how things look beneath it undoes a day of work in a second. So watch carefully and intervene rarely. Restraint is not passivity; it is the most active contribution most patients can make in the first fortnight.
-
When should I call rather than manage it myself?
Call if redness spreads outward rather than fading, if drainage becomes cloudy, discolored, or develops an odor, if pain increases after it had begun to settle, if you develop a fever, or if any part of the incision separates. None of those is an occasion for a stronger antiseptic. They are occasions for someone to look at the wound. So do not try to treat them at home. I would always far rather see a patient unnecessarily than see one too late.
