An arm lift, known medically as brachioplasty, is a surgical procedure that removes excess skin and fat from the upper arms to create a smoother, more toned contour. It’s most commonly sought by people who have loose, hanging skin after significant weight loss or as a result of aging, where the skin has lost its elasticity and no longer tightens on its own. The average surgeon’s fee is $6,192, though the full cost runs higher once facility and anesthesia fees are included.
Why People Get an Arm Lift
The upper arm stores fat in two distinct layers separated by a sheet of connective tissue. When someone loses a large amount of weight, or when skin naturally thins with age, that tissue can’t snap back into place. The result is what many people call “bat wings,” where skin and fat hang from the underside of the arm between the elbow and armpit. Exercise can strengthen the underlying muscles (the biceps, triceps, and deltoid), but it can’t tighten skin that has already stretched beyond its ability to recover.
Diet and exercise alone don’t address this excess skin. That’s the gap an arm lift fills. It physically removes the tissue that no longer responds to lifestyle changes.
Who Qualifies for the Procedure
According to the American Society of Plastic Surgeons, good candidates are adults with significant upper arm skin laxity whose weight is relatively stable and who are not significantly overweight. You don’t need to be a specific age, but you do need to be in generally good health without conditions that impair wound healing. Smokers need to quit at least four weeks before surgery, since nicotine restricts blood flow and sharply increases the risk of complications like poor wound healing and wider scars.
Mini vs. Full Arm Lift
Not every arm lift looks the same. The two main options differ in how much skin is removed and where the incision goes.
- Mini brachioplasty: Uses a small incision hidden in the armpit. It works for people with mild looseness concentrated near the underarm area. The tradeoff is that it can only address a limited zone of skin.
- Full brachioplasty: Involves an incision that runs from the elbow up to the chest, sometimes extending along the side of the torso for patients with significant excess tissue. This version removes far more skin and reshapes the entire upper arm.
Some surgeons combine liposuction with either approach to reduce fat volume before removing skin, which can improve the final contour.
What Happens During Surgery
You’ll lie face up with your arms out to the sides and elbows bent at 90 degrees. The surgeon marks the skin beforehand with cross-hatch lines that serve as alignment guides for closing the incision precisely later.
The actual cutting stays in the superficial fat layer, well above the deeper structures that house the major nerves and blood vessels of the arm. This protects the median, ulnar, and radial nerves, along with the brachial artery. The surgeon determines exactly how much skin to remove by temporarily pinching the tissue together, a technique called “tailor tacking,” which prevents taking too much or too little.
Once the excess is removed, the wound is closed in layers. The deep connective tissue is stitched together first to reduce tension on the outer skin, minimize dead space where fluid could collect, and support a smoother result. The incision is then taped and covered with compression garments that extend from the hand up through the forearm and upper arm. The whole process is then repeated on the other side.
Where the Scar Goes
Scar placement is one of the biggest decisions in an arm lift, and surgeons differ on the best approach. The two main options are a medial incision, which runs along the inner arm in the groove between the biceps and triceps, and a posterior incision, which sits along the back of the arm where it’s less visible from the front.
A survey published in the Annals of Plastic Surgery found that, once scars had fully matured, a straight medial scar scored highest for overall appearance (rated 4.0 out of 5), while a wavy medial scar scored lowest (2.03). Posterior scars fell in between. Some surgeons also use Z-shaped or S-shaped incision patterns at the armpit to reduce the risk of scar tightening that could limit arm movement.
Scars are typically red and raised for the first several months, then gradually flatten and fade over one to two years. They never disappear completely, which is the primary cosmetic tradeoff of the procedure.
Recovery Timeline
The first week is the most restrictive. Expect swelling, bruising, and soreness that limits your ability to lift or extend your arms fully. Compression garments are worn during this phase to control swelling and support the healing tissue.
Most people with desk jobs return to work within one to two weeks, as long as they can keep their arms close to their body and are no longer taking prescription pain medication. During weeks two through four, light cardio that doesn’t pull on the incision (like walking or stationary cycling) is usually fine, along with gentle lower body activity.
Around four to six weeks, light upper body exercises below shoulder height may be introduced. Full activity, including overhead lifting and vigorous exercise, is typically cleared at about six weeks if the tissue is healing well and strength is returning. Your surgeon will confirm this based on how your incisions look at follow-up visits.
Risks and Complications
A retrospective study of brachioplasty outcomes found an overall complication rate of 25 percent. That number sounds high, but it includes a range of severity. The most common issues were fluid collections under the skin (seroma), raised or thickened scars, wound separation, infection, and nerve injury causing numbness along the inner arm.
Numbness is worth particular attention. The nerves that provide sensation to the inner arm and forearm run through the fat layer just beneath the skin. Careful surgical technique protects them, but temporary numbness is common, and in some cases, sensation changes are permanent. Patients who’ve had prior breast or armpit surgery also face a higher risk of disrupting lymphatic drainage in the arm, which can cause lasting swelling.
How Long Results Last
The skin and fat removed during an arm lift are gone permanently, but your arms will continue to age. Gravity, sun exposure, and natural collagen loss will gradually loosen skin over time, though the improvement from surgery remains visible for years.
The single biggest factor in preserving your results is weight stability. Moderate weight fluctuations usually don’t undo the surgery, but significant weight gain stretches the remaining skin, adds new fat deposits to the arms, and can widen scars by putting pressure on the incision lines. Extreme weight loss after the procedure can cause skin to loosen again, sometimes enough to require a revision surgery. People who maintain a stable weight consistently report the longest-lasting satisfaction with their results.
Cost Breakdown
The $6,192 average reported by the American Society of Plastic Surgeons covers the surgeon’s fee only. On top of that, you’ll pay separately for anesthesia, the operating facility, pre-surgery medical tests, compression garments, and prescriptions. Total out-of-pocket costs typically land well above the surgeon’s fee alone, varying widely by region and the extent of the procedure. Insurance rarely covers brachioplasty unless there’s a documented medical need, such as chronic skin infections in the folds of excess tissue.
