An arm lift removes the excess skin from the inner surface of the arm. It is the only way to correct laxity once the skin no longer pulls back, and it leaves a visible scar.
After significant weight loss, or simply over the years, the skin on the inner arm stretches and hangs. There is no exercise, cream or technology that pulls it back: once the skin has lost its elasticity, the only way to remove it is to cut it away. The surgery removes a strip of skin and fat and gives the arm back a firm contour, with a change in shape that is usually very noticeable.
And here comes the part that has to be said plainly, because it is the part that decides satisfaction with this surgery. The scar runs down the inner surface of the arm, from the armpit to near the elbow. It shows with short sleeves, it shows when you raise your arm, and in that area — thin skin, under constant movement — it tends to widen more than elsewhere on the body. It is the operation in the catalogue with the worst ratio between how much it improves the contour and the mark it leaves. Anyone not prepared to trade laxity for a scar should not have it done.
It usually helps when there is
- Hanging skin on the inner arm that responds to nothing else.
- Significant weight loss, stable for at least six months.
- Stable weight and clear expectations about the scar.
- Functional bother: chafing, trouble with clothes, irritated skin.
- An explicit willingness to accept a visible, permanent scar.
Worth discussing first if
- Mild laxity, where the scar may not be worth the improvement.
- A tendency to hypertrophic scars or keloids.
- Current smoking.
- Weight loss still under way.
- Putting appearance above function without accepting the mark.
None of these rules the procedure out on its own; all of them change the conversation.
According to how much skin is in excess
The length of the scar is determined by the extent of the laxity, not by preference.
Liposuction alone
When the problem is fat and the skin still has elasticity. No significant scar. It does not correct laxity.
Short-scar arm lift
A scar limited to the armpit, for mild laxity of the upper third of the arm. Limited reach but a hidden scar.
Full arm lift
A scar from the armpit to near the elbow. It is the one that really corrects marked laxity, and the one that leaves the visible mark.
Where the scar goes and why it matters
The scar is placed in the groove on the inner surface of the arm, which is the position least visible with the arm down. Placing it on the back surface — which is sometimes proposed — makes it visible from behind and offers no advantage. Closure is done in layers and without tension, with deep sutures taking the load, because a scar under tension in this area will certainly widen.
The course of the medial cutaneous nerve of the forearm and the lymphatic system of the arm are respected. Injury to the lymphatics can produce persistent swelling of the hand and forearm, and it is a complication that is hard to manage.
The excision is marked standing, pinching the skin with the arm raised out to the side, and confirmed on the table. Removing too much makes closure impossible; removing too little leaves the laxity you came to have corrected.
What the process is like
From the first consultation to discharge, with the usual timings for this surgery.
Consultation
Whether the problem is fat, skin or both is assessed, the length of the scar is defined and how it is going to look is discussed in detail. It is the most important part of this consultation.
Before surgery
Laboratory tests and anaesthetic assessment. Stopping smoking. The informed consent is signed.
Surgery
Under general anaesthesia. Marking while standing, liposuction first where appropriate, removal of the strip of skin and closure in layers. A compression sleeve at the end.
Follow-up
Reviews at one week, one month, the third month and a year, with active scar treatment from three weeks onwards.
Week by week
Functional recovery is quick; the scar needs a year.
-
Days 1 to 7
Compression sleeve at all times, swelling of the arms and hands and discomfort moving the shoulder. Arms raised when resting.
-
Weeks 2 to 4
Back to office work at around ten to fifteen days. No lifting. Shoulder movement built back up gradually.
-
Weeks 6 to 12
Exercise built back up once authorised. Active scar treatment begins with silicone, pressure and sun protection.
-
Months 6 to 18
The scar goes from red and raised to paler and flatter. It is a long process and in this area slower than in others.
Risks, and what is not promised
The dominant risk is the scar itself: in this area it frequently widens, can become hypertrophic or keloid and its treatment goes on for months. It may need injections or even a surgical revision, with no guarantee of improvement.
Other risks: seroma, haematoma, infection, wound breakdown, altered or lost sensation on the inner surface of the arm, and lymphoedema from injury to the lymphatic vessels, which produces persistent swelling of the hand and forearm and is difficult to manage.
No discreet scar is promised. This is the operation in which that warning weighs most, and it is why the conversation beforehand is so detailed. These risks are reduced by closure in layers without tension, respect for the lymphatics and early scar treatment. They are not eliminated. The ones that apply to your case are set down in writing in the informed consent.

The questions we are asked most about arm lifts
It runs down the inner surface of the arm, from the armpit to near the elbow, and it is visible with short sleeves. In this area the skin is thin and in constant movement, so the scar tends to widen more than elsewhere on the body.
It is looked after from three weeks onwards with silicone, pressure and sun protection, and it improves considerably over the first year. It does not disappear.
If the problem is fat and the skin still has elasticity, yes: liposuction resolves it with no significant scar. It is the best possible situation and it is checked in the consultation.
If the skin no longer pulls back, there is no alternative. No radiofrequency, ultrasound or thread device removes excess skin, however it is advertised.
It depends on how much the laxity limits you. For someone with hanging skin after significant weight loss, skin that chafes, irritates and dictates their clothes, the change is usually worth it by some margin.
For mild laxity motivated only by appearance, the honest answer is that often it is not worth it. It is discussed in the consultation.
For the first weeks yes, it is normal and it is managed with the compression sleeve and by keeping the arms raised when resting.
What is not normal is for it to persist: if the swelling continues beyond a few months it may be lymphoedema, an infrequent complication that is picked up at the reviews and needs specific treatment.
