A surgery about contour, not weight
Many people think of liposuction as weight-loss surgery. Its actual purpose is somewhat different. It is not about reducing overall body weight but about removing fat from specific areas to change the lines of the body.
Dieting does not let you choose which area slims down first, because the body draws on fat evenly from all over. That is why, no matter how much weight is lost, certain areas such as the upper arms or inner thighs stubbornly remain.
Liposuction targets those areas directly. If dieting reduces the overall amount, liposuction is closer to changing the distribution.
That is why the number on the scale often does not drop as much as expected after surgery. Fat has a large volume relative to its weight. This is why it is common for patients to be surprised that their clothing size has changed while their weight has not.
Which layer under the skin holds the fat?
What liposuction addresses is subcutaneous fat. It is the layer directly beneath the skin, the flesh you can grab with your hand.
Even within subcutaneous fat, there are separate layers. The superficial layer just under the skin is involved in the skin's blood circulation and sensation, and the deep layer below it holds a thick amount of fat.
This distinction matters in surgery. Suctioning excessively into the superficial layer can thin the skin and leave an uneven surface. Conversely, being too cautious means the contour does not come out as intended.
Visceral fat, which sits between the organs in the abdomen, is not removed by liposuction. If a protruding abdomen is caused by visceral fat, it must be approached through weight loss rather than surgery, so we first distinguish what the problem is during the consultation.
| Category | Description |
|---|---|
| Superficial subcutaneous fat layer | The layer just under the skin, involved in the skin's blood circulation and sensation. |
| Deep subcutaneous fat layer | The layer below it, where fat sits thickly. |
| Visceral fat | Fat between the organs in the abdomen; not removed by liposuction. |
Tumescent solution, the step that prepares the surgery
The fat is not extracted right away. First, a solution is infused into the surgical area, and this is called tumescent. It is a medical term meaning swollen and firm.
The solution mixes local anesthetic, a vasoconstrictor, and normal saline. The purpose is to obtain anesthetic and hemostatic effects at the same time. Constricting the vessels reduces bleeding and bruising.
It has another role. As the solution permeates the fat layer, the fat swells and the spaces between tissues widen. The fat separates more readily from the surrounding tissue, and it can be suctioned with less force.
Time is needed for the solution to spread sufficiently. Rushing leaves the anesthetic and hemostatic effects uneven, which increases bleeding.
What the cannula does
A thin tube called a cannula is inserted through a small incision. It has openings at the tip and connects to a suction device at the other end.
Moving the cannula back and forth breaks the fat tissue into small pieces, which are drawn out through the tube by negative pressure. Rather than digging the fat out, the technique creates multiple channels along the layer. Approaching from several directions like the ribs of a fan is what makes the surface come out even.
The thickness and length of the cannula affect the result. A thick cannula extracts quickly but tends to leave a rough surface, while a thin one is precise but takes more time.
The incision site is part of the design as well. Creases or spots hidden by clothing are chosen so that scars are less visible. How a scar forms depends on the location and direction of the incision.
How TheLINE approaches liposuction
TheLINE Plastic Surgery Clinic gives equal weight to what is removed and what is left behind, because fat contains SVF, which includes stem cells.
So instead of forcibly clearing out the entire fat layer, TheLINE selectively suctions the middle layer and leaves the superficial fat that protects the skin. We also reapply SVF separated from the suctioned fat to the surgical area to support recovery. This separation is carried out in the dedicated laboratory on the fifth floor of the clinic.
Incisions are made 2 millimeters in size and hidden in creases, and long cannulas are used so that only the necessary areas are accessed. It is a choice made to reduce scarring while smoothing evenly from multiple directions.
Dr. Jaeho Cho, a board-certified general surgeon, has performed liposuction since 2007 and has studied fat and SVF, and Dr. Yoosuk Chung, a board-certified plastic surgeon, takes part in both harvesting and surgery.
How does recovery proceed?
A compression garment is worn right after surgery. Because space is left where the fat was removed, compression helps the tissue settle into place and reduces swelling. Continuing for several weeks is standard.
Swelling and bruising subside over time. With tumescent solution still remaining and the tissue responding, some of this is an expected part of the course. The detailed timeline is covered separately in swelling and bruising after liposuction.
The final contour is not visible right away. It takes several months for the swelling to subside and the tissue to settle, so we do not judge the result by how it looks immediately after surgery.
When you can return to daily life depends on the area and extent. Desk work resumes relatively quickly, but exercise is guided to be resumed in stages after some time.
Limits to keep in mind
There is a limit to how much can be removed at one time. More is not better, because bleeding and fluid shifts place a greater burden on the body, so the plan stays within a safe range. When the area is wide, the procedure may be divided into stages.
Skin elasticity also determines the outcome. The skin has to contract along with the space left by the fat for the contour to come out smooth. If elasticity is insufficient, loose skin may remain and a lift may be considered alongside.
There are possible side effects. Bleeding, infection, bruising, reduced sensation, surface irregularities, and left-right asymmetry can occur, and pigmentation rarely remains. Unexpected inflammation or bleeding can occur and the degree varies between individuals, so caution is required.
It is also not a substitute for obesity treatment. When body weight is high, the recommended order is to lose weight first and then refine the remaining areas.
Frequently Asked Questions
How much weight will I lose with liposuction?
Often not as much as expected. Fat has a large volume relative to its weight, so clothing size may change while the number on the scale barely moves. It is more accurate to understand it as surgery that changes the contour rather than the weight.
Can visceral fat be removed too?
Liposuction addresses subcutaneous fat beneath the skin, so visceral fat between the organs is not a target. If a protruding abdomen is caused by visceral fat, it is approached through weight loss.
Can several areas be done at once?
It is possible, but the wider the extent, the greater the burden of bleeding and fluid shifts. We plan so as not to exceed the safe range and divide the procedure into stages when necessary.
When can I see the result?
It takes several months for the swelling to subside and the tissue to settle. The appearance right after surgery is not the final result, so we review it over the course of recovery.
What makes liposuction at TheLINE Plastic Surgery Clinic different?
TheLINE considers what is removed and what is left behind together. To preserve the SVF within the fat, we selectively suction the middle layer and reapply the separated SVF to the surgical area to support recovery. Dr. Jaeho Cho and Dr. Yoosuk Chung handle everything from harvesting to surgery themselves.
