Where are arm lift scars, and how do they heal?

An arm lift leaves a scar on the inner side of the upper arm, usually running from the armpit towards the elbow. If the loose skin is limited to the area near the armpit, a shorter scar hidden in the armpit can be enough, and after major weight loss the line may continue onto the side of the chest. The scar fades over about 12 months but never disappears completely.
The scar is the part of arm lift surgery in Istanbul that people weigh up most carefully, because it is the permanent exchange for removing loose skin. Knowing where it will lie and how it behaves as it matures helps you decide whether that exchange is right for you.
Three scar patterns for three kinds of loose skin
The length of the scar follows the loose skin: it only needs to reach as far as the skin that has to be removed.
Mini arm lift: a short scar in the armpit, for a small amount of loose skin close to the armpit. It is the most discreet option but cannot tighten skin further down the arm.
Standard arm lift: a line on the inner arm from the armpit towards the elbow, for looseness along most of the upper arm.
Extended arm lift: the standard line plus an extension onto the side of the chest, used after major weight loss when the looseness continues below the armpit.
Dr. Semih Yıldız decides the length of the incision and how much skin to remove based on the shape of your arms. The lines are drawn with your arms raised, because in that position loose skin hangs most clearly and shows how far it extends.
Where the line sits and who sees it
With your arms relaxed at your sides, the inner arm faces your body, so the scar is largely out of view. It becomes visible when you lift your arms: reaching up to a shelf, waving, tying your hair, or wearing sleeveless clothes or swimwear. A short sleeve covers the part near the armpit, while the section closer to the elbow can show when your arms are raised.
The line is placed either slightly towards the front, in the natural groove between the biceps and triceps, or slightly further back. Each position changes the angle from which the scar can be seen, and none hides it from every direction once the arm is lifted. Where the scar crosses the armpit, it is planned so that it does not tighten into a band that pulls when you raise your arm.
Why arm scars need patience
The skin of the upper arm moves with every reach and lift, and the closure carries some tension. For this reason arm scars widen or thicken more often than, for example, scars on the face. A typical first year looks like this:
First 2–3 weeks: a fine line, often under tapes, that looks neat while the wound closes.
Months 1–3: the scar usually turns pink or red and feels firm, slightly raised and sometimes itchy. It often looks worse than expected at this stage, which is part of normal healing.
Months 3–6: the colour softens and the scar starts to flatten.
Months 6–12: it gradually pales and becomes softer. Most of the change happens within the first year, and some scars keep improving slowly after that.
Even a well-healed arm scar stays visible as a fine, paler line. Because it tans less than the skin around it, it can look lighter on sun-tanned arms.
Looking after the scar
Scar care begins only once the wound has fully closed, usually after the first few weeks, and once this has been confirmed at a check-up or from your photos.
Silicone gel or silicone sheets are the most widely recommended home treatment for healing scars. They are applied every day for several months.
Protect the scar from the sun for at least the first year with clothing or a high-protection sunscreen, as fresh scars darken easily.
Avoid pulling on the scar in the first weeks: no heavy lifting and no forceful overhead stretching until you are cleared.
Stay away from nicotine for at least 4 weeks after surgery, as before it. Nicotine narrows small blood vessels and slows wound healing.
Once the scar is closed and no longer tender, gentle massage with a plain moisturiser can help it feel softer.
The compression sleeves you wear for about 4–6 weeks mainly control swelling, but they also support the healing skin while it is most vulnerable.
What can make the scar worse
Some factors lie outside anyone’s control. A personal or family tendency to thick, raised scars (hypertrophic scars or keloids) matters, and so does a darker skin type, which is more prone to raised scars and colour changes; both are worth mentioning at your assessment. Other factors can be influenced: smoking, a wound infection or an area of delayed healing, early strain on the arm and large weight changes after surgery all make a wider scar more likely.
If a scar starts to thicken, it can be treated early, for example with silicone and, where suitable, steroid injections. A scar that remains wide once it has fully matured can sometimes be improved with a small revision, which is usually considered only after about a year.
Scar or contour: weighing the exchange
An arm lift always trades loose skin for a scar. Shortening the scar too much leaves skin behind or creates small puckers at its ends, so it is planned to be as long as necessary and as short as possible. If the looseness reaches the elbow, a short armpit scar cannot correct it.
If your arms mainly carry fat and the skin is still firm, liposuction alone may be enough, with only small entry scars. And if a visible line on the inner arm would bother you more than the loose skin does today, that is a valid reason not to have the operation.

Frequently asked questions
Will people notice my arm lift scar in a T-shirt?
Usually not while your arms are relaxed, because the scar lies on the inner side of the arm, which faces your body. A short sleeve covers the part near the armpit. The section closer to the elbow can show when you raise your arms, and sleeveless tops or swimwear reveal more of it. As the scar pales over the first year, it becomes less noticeable.
Can laser treatment remove an arm lift scar?
No treatment removes a scar completely. Laser treatment can sometimes reduce redness or improve texture, and thick, raised scars may respond to steroid injections. A scar that is still wide once it has matured, usually after about a year, can occasionally be improved with a small revision. Which option makes sense depends on how your scar looks once it has settled.
Will the scar limit how far I can raise my arm?
Once healed, an arm lift scar should not limit normal movement. In the first weeks the inner arm feels tight when you lift or straighten it, and this eases as the swelling settles. The part of the scar that crosses the armpit is planned to avoid a tight band. If a cord-like tightness does develop, it is assessed and can usually be treated.
