Hello, this is Dr. Yoonkeun Kim, Director at TheLINE Plastic Surgery, a clinic specializing in body contouring.
One of the concerns many women share is arms that look thick because of the fat on them. The biggest source of stress is often not simply 'thick upper arms' but the presence of the **accessory breast**, which appears when the area between the arm and the chest is not smooth. This accessory breast tissue rarely goes away no matter how much dieting is done, and it bulges out to the side in sleeveless tops, making the upper body look much wider. It also stays on your mind whenever you wear underwear or a swimsuit. This patient, at 154cm and 54kg, was at an appropriate overall weight, but she named as her biggest concern the way the straight flow of her upper body was interrupted by the volume of her upper arms together with an unusually assertive accessory breast. To address this underlying cause, we reduced the circumference of the entire upper arm while also performing accessory breast liposuction to clear the deep fat on the inner side of the armpit, designing a smooth, uninterrupted shoulder line.
Many people assume that losing upper arm fat alone will produce a pretty line, but a genuinely slim mood actually depends on how cleanly the 'armpit borderline', where the arm meets the torso, is organized. At TheLINE we used our handmade technique to shave down the volume on the outer upper arm and to flatten the bulging fat layer of the accessory breast area, dramatically reducing the overall bulk of the upper body. When the arm and accessory breast are suctioned as one organic line in this way, the shoulders look narrower from the front, and there is an extreme smoothness with no flesh pushing out even when the arms are down. This goes beyond simply removing fat; it is a demanding sculpting process that changes the frame of the upper body itself into something more delicate.
These are the patient's pre-operative photos.
What makes this level of refined detail possible is TheLINE's own SVF technology (regenerative growth factors harvested from fat). The accessory breast and armpit areas have thin, sensitive skin, so there is a risk of the skin loosening or wrinkling after suction. SVF arm liposuction, however, injects concentrated SVF (regenerative growth factors harvested from fat) energy during the operation, giving strong contractile support so that the skin settles firmly where the fat was removed. Because the abundant growth factors in SVF (regenerative growth factors harvested from fat) increase the density between tissues, the patient was able to see a firm, smooth armpit line, as if conditioned by exercise, without the skin sagging after surgery.
SVF technology also shows remarkable recovery resilience even after extensive suction covering the accessory breast and the entire arm. The strong regenerative energy of SVF supports smooth microcirculation at the surgical site and helps irritated tissue heal quickly, sharply reducing bruising and swelling. Thanks to this, the patient carried less of a burden during recovery and experienced high psychological satisfaction as she watched her arms grow slimmer and her armpit line lighter day by day.
Standing in front of the mirror now, none of her former hesitation remains. She no longer needs to tug her clothing up to hide the accessory breast, or pile on layers to cover her upper arms. A single loose sleeveless top is now enough, and she is fully enjoying the delicate lines that were hers all along. The moment the flesh on the inner armpit she once wanted to hide turns into the smoothest, most confident straight line - that dramatic change can come to your daily life as well. Where TheLINE's careful hands reach, set free your most radiant silhouette.
