No wound that cuts through the full thickness of the skin heals without a scar. There is no such thing as scarless surgery, and any promotion that uses the phrase is promising something that does not exist. What surgery genuinely decides is not whether there will be a scar but where it will sit, how long it will be, which clothes it will show under and how it will heal.
All of that is settled before the operation. A scar is not a side effect of surgery; it is part of the plan.
The placement of an incision is a design decision
When a surgeon decides where an incision goes, three things have to be solved at once:
- Access. The view and the working space the procedure needs in order to be done safely.
- Blood supply. The incision is planned so as to protect the structures that carry circulation to the tissue. Tissue whose blood supply is compromised heals poorly and leaves a poor scar.
- Concealment. Placing the scar along a natural line of the body or within an area that clothing covers.
Those three do not always point to the same place, and a balance is struck between them. An important conclusion follows: a smaller incision is not always better. Inadequate access means pulling and stretching the tissue more than it should be, which spoils the result and produces a worse scar because it heals under tension. The length of an incision is not a measure of quality; it is a choice within a plan.
Where is the scar for each procedure?
The logic of concealment is always the same: place the scar on a line the body already has. A natural fold, the colour border between two tissues, the hairline, or a line covered by underwear.
- Breast augmentation. The most commonly used site is the inframammary fold, where the scar stays on the line at which the breast naturally meets the chest wall and is hidden beneath the breast when standing. The areolar border uses a colour boundary instead. Which route is chosen depends on the type and volume of the implant and on the characteristics of the tissue.
- Breast reduction and breast lift. Here the scar is unavoidably on the front of the breast: around the areola, down a vertical limb, and often in the inframammary fold. Concealment is limited in these operations and that has to be said plainly at the outset. What the patient accepts is a visible scar in exchange for the removal of excess tissue.
- Abdominoplasty. The incision is planned as low and as horizontal as possible, the aim being that it stays under underwear or a swimsuit. In a full abdominoplasty the navel is repositioned, so a second scar forms around it. Coming to the consultation in the underwear you usually wear can directly affect where the incision is planned.
- Facelift. The scar begins inside the hairline, follows the natural crease in front of the ear and continues behind it. On the face, concealment relies mostly on those three natural borders.
- Upper eyelid surgery. The incision is placed in the eyelid's own crease and usually stays inside it when the eye is open. It is one of the most favourable areas of the face for a scar.
- Otoplasty. The scar lies behind the ear, in the groove where the ear meets the scalp, and is not visible from the front.
- Liposuction. What is involved is a few access points of a few millimetres, and those too are placed in folds and along the swimsuit line rather than at random.
- Rhinoplasty. In the closed technique every incision is inside the nose. The open technique adds a few millimetres across the columella, the strip of skin between the nostrils; the resulting scar is usually hard to see once it has matured.
Hiding is not the same as removing
A hidden scar is still there. A scar that does not show when dressed shows when undressed; one that does not show standing may show at a certain angle or when the arm is raised. So the question to ask in a consultation is not whether there will be a scar. The right question is: in what situations will it be visible?
The answer depends on the patient's life. For someone who swims regularly the swimsuit line matters; for someone who wears stage clothing the back does. Telling the surgeon this is a contribution that can genuinely change the plan for the incision.
How long does a surgical scar take to fade?
A surgical scar takes twelve to eighteen months to mature. What it goes through in that time catches most patients unprepared, because it starts as a fine line and then gets worse.
- The first weeks. The sutures come out, the line is thin and usually looks good. This is a temporary phase.
- From roughly the fourth week to the third month. Production of repair tissue accelerates: the scar reddens, becomes raised and firms up. This is normal and is not in itself a sign of poor healing. It is usually the period in which patients panic and conclude the operation has failed.
- From the third to the sixth month. The scar is at its most conspicuous.
- From the sixth to the eighteenth month. Maturation: the redness fades, the elevation settles, the tissue softens and the colour moves towards that of the surrounding skin.
Wound healing is not an arbitrary subject on this site. Prof. Dr. Ferit Demirkan's specialty thesis compared the effects of different types of electrical current on wound healing (Gazi University, 1997), and a study of skin-graft loss due to infection that he co-authored appeared in Annals of Plastic Surgery in 2005. How a scar will behave is as old a question as surgery itself.
So does a scar ever go away? No. A mature scar fades, flattens and settles towards the colour of the surrounding skin, but it does not disappear. The practical consequence is that judging a scar takes at least a year: the scar you see at six months is not the final one. It is one of the reasons a revision is delayed as well.
Not everyone's scar heals the same way
Some of what determines how a scar heals is personal and cannot be changed:
- Genetics. The single strongest factor. If you or your family have a history of hypertrophic (raised) scars or keloids, that has to be shared at the consultation; it can change the plan, the site of the incision and the scar-care programme.
- Skin type. Darker skin types have a higher tendency towards raised scars and keloids.
- Age. The repair response is stronger in younger skin, which can keep a scar red and raised for longer.
- Region. Scars tend to heal less well in areas under constant tension such as the front of the chest, the shoulder and the back. The eyelid is among the best-healing areas. Two scars on two different areas of the same person may not resemble each other.
What can I do to help a scar heal better?
The fate of a scar is not entirely genetic. A few things genuinely change the outcome and are entirely in your control.
- Smoking. The strongest of the modifiable factors, and it works on two fronts: nicotine narrows the small vessels, and carbon monoxide reduces the oxygen the blood can carry. Both impair wound healing directly. Stopping before and after surgery is not a surgeon's aesthetic preference but a safety requirement.
- Tension. Mechanical tension across a scar widens it over time. That is why you are asked not to lift anything heavy in the early period, not to strain the area, and to use the recommended garment or tape.
- Sun. A scar that has not finished maturing can darken permanently if it is exposed to the sun, and that change in colour is difficult to reverse afterwards. A scar should be protected for at least a year, by clothing, tape or a high-factor sunscreen.
- Silicone. In international scar-management recommendations, silicone gel or silicone sheeting is the first-line way of supporting scar quality during maturation. When to start and how long to continue is decided by the surgeon.
- Stable weight. Significant weight gain or loss after surgery can widen a scar, particularly on the trunk.
- Attending follow-up. A scar showing a tendency to thicken leaves more options open if it is noticed early. Treating a thickened scar late takes longer.
Hypertrophic scar or keloid: what is the difference?
Two situations need to be told apart. A hypertrophic scar is raised but stays within the borders of the original incision and partly regresses over time. A keloid spreads beyond the borders of the incision into surrounding healthy skin and does not regress on its own.
Both have early options: silicone, pressure, intralesional injections given by the doctor, and in some cases laser. Surgical scar revision is the last step, and it is worth knowing what it does: scar revision does not remove a scar, it aims to put a better one in its place. In a keloid this is more delicate still, because a keloid excised on its own tends to recur; it is only considered together with an adjuvant treatment. The same rule about waiting applies here, and operating on a scar that has not finished maturing usually makes matters worse.
Questions for the consultation
- Exactly where will the incision be, and roughly how long?
- Which clothes will hide this scar, and in what situations will it show?
- How do scars tend to heal in my skin type and in this area?
- There is a history of raised scars in my family; does that change the plan?
- What do you recommend for scar care, when does it start and how long does it last?
- If the scar heals worse than expected, what are the options and how is that managed?
A plan that answers those questions clearly is not merely more honest than a plan that never mentions the scar; it is a better plan. Having discussed the site of the incision beforehand is what keeps the line that appears afterwards from being a surprise.
