Liposuction
Liposuction removes fat from beneath the skin through small incisions, using a thin tube called a cannula. It reshapes areas where fat persists despite a stable weight, such as the jawline, under the chin, the abdomen or the thighs. It is a contouring operation, not a weight-loss treatment, and it does not tighten loose skin.
At Violacell Plastic Surgery, Dr. Kim currently provides non-surgical treatment and does not perform liposuction there. This page is a plastic surgeon's guide: what liposuction can and cannot do, and how to tell whether your concern needs surgery or can be treated without it, for example with Ulthera for the jawline.
- What it treats
- Localized fat in the face, jawline, neck and body that does not respond well to diet and exercise.
- Anesthesia
- Local anesthesia with tumescent fluid, often with sedation, for small areas; sedation or general anesthesia for larger or multiple areas.
- Operating time
- Typically about 1 hour for a small area such as under the chin, and several hours for multiple body areas. It varies with the plan.
- Compression
- A compression garment or chin strap is usually worn for several weeks, as instructed.
- Recovery
- Many people return to light daily activities within days to about 1–2 weeks, depending on the areas treated. Swelling settles gradually over several months.
What a Surgeon's View Adds to Contouring the Lower Face
Liposuction removes fat; it does not tighten skin. On the jawline, telling fat from laxity is the whole decision.
Fat, gland or muscle
A full lower face can be fat, salivary glands or chewing muscle. He separates them, on the ultrasound image and by touch, before planning.
Ulthera at the fat level
Where fat is the issue and the amount is modest, Ulthera lines placed at the fat level can help slim the jawline without surgery.
Skin that follows
Thermage firms the skin so it sits well over a slimmer contour.
Fat or Loose Skin?
When fat is the main problem
A full jawline, a double chin or a bulge on the abdomen or thighs can come from fat that sits under skin that is still reasonably firm. Liposuction suits this situation best, because the skin can shrink back over the new contour.
When the skin has loosened
Sagging comes from stretched skin and descended deeper tissue, not only from fat. Removing fat under loose skin can leave the skin hanging more, or make the area look hollow and wrinkled.
When lifting is needed instead
For a sagging jawline, jowls or loose neck skin, a mini facelift or facelift repositions tissue and removes excess skin. Neck liposuction is often combined with a lift rather than replacing it. You can read more in Mini facelift or full facelift?
A simple self-check
Pinch the area gently. A thick, soft roll that returns quickly suggests fat. Thin skin that stays creased or folds easily, especially when you tilt your head down, suggests laxity. An examination is needed to judge both, along with muscle and bone structure.
Glossary
- Liposuction
- Surgical removal of fat through a cannula connected to suction.
- Cannula
- A thin, blunt-tipped metal tube inserted through a small incision to break up and remove fat.
- Tumescent fluid
- A large volume of dilute local anesthetic (lidocaine) and adrenaline (epinephrine) injected into the fat before suction to reduce pain and bleeding.
- Aspirate
- The mixture of fat and fluid removed during liposuction.
- Skin laxity
- Loss of skin firmness and elasticity, so the skin stretches and sags.
- Seroma
- A pocket of clear fluid that collects under the skin after surgery.
- Platysma
- The thin sheet of muscle in the front of the neck. When it separates, vertical neck bands can appear.
Common Treatment Areas
Fat distribution is partly inherited, and some areas resist diet and exercise. The areas below are commonly treated. Which ones are suitable depends on fat thickness, skin quality and overall body proportions.
| Area | Typical concern | Points to consider |
|---|---|---|
| Under the chin (submental) | A double chin that blurs the angle between the chin and neck | Neck bands, loose skin or a small chin can limit the result |
| Jawline and lower face | Fullness along the jaw and lower cheeks | Jowls from sagging, not fat, need lifting instead |
| Cheeks | Facial fullness | Removing too much can age the face; volume often needs to be preserved |
| Abdomen and waist | Fat around the belly and flanks | Fat behind the abdominal muscles cannot be removed; loose skin or separated muscles may need other surgery |
| Thighs | Inner or outer thigh fullness | Contour irregularities are a particular concern here |
| Arms | Fullness on the back of the upper arm | Loose arm skin may not tighten enough |
| Back and bra line | Rolls of fat around the bra strap | Tissue is often firmer and more fibrous |
How Liposuction Works
Small incisions, usually a few millimeters long, are placed in inconspicuous spots. Tumescent fluid is then injected into the fat. It numbs the area, narrows blood vessels to reduce bleeding and makes the fat easier to remove. Today most liposuction is performed with this tumescent or a similar "wet" technique.
A cannula is moved back and forth in the fat layer in a fan-like pattern, loosening fat that is drawn out by suction. Thinner cannulas allow finer control and are used in delicate areas such as the face; larger ones remove fat more quickly in larger body areas. The surgeon works in an even layer and leaves a cushion of fat under the skin, because removing fat too close to the skin is a common cause of dents and ripples.
Suction-assisted liposuction
The standard method. The cannula is moved by hand and fat is removed by suction alone. It remains widely used for most areas.
Power-assisted liposuction
A motorized cannula vibrates in small movements, which can make fibrous areas, such as the back or previously treated areas, easier to work in.
Ultrasound-assisted liposuction
Ultrasound energy is used to loosen and emulsify fat before suction. It can help in dense fat, but heat energy carries a risk of burns and needs careful technique.
Laser-assisted and other options
Laser or radiofrequency devices heat the fat and the tissue under the skin. Some are promoted for skin tightening, but the amount of tightening varies and does not replace skin removal when laxity is significant.
No single device is right for every area or every person. The choice depends on the area, fat consistency, skin quality and previous procedures.
Face, Jawline and Neck
Facial liposuction is usually done through tiny incisions under the chin and behind or below the earlobes, using fine cannulas. The goal is to define the jawline and the angle between the chin and neck, not to make the face as thin as possible. The face needs some fat to look healthy, and the fat in the face decreases naturally with age.
A branch of the facial nerve that moves the lower lip runs near the jawline. Working in the correct layer protects it; temporary weakness of the lower lip is a recognized but uncommon risk. Neck fat can also lie beneath the platysma muscle, where liposuction does not reach it.
Who It May Suit
- Adults at or near a stable weight with localized fat
- People whose skin is still reasonably firm
- People with fullness under the chin or along the jaw, without significant sagging
- People in good general health who do not smoke, or who can stop before and after surgery
- People who understand that liposuction refines shape rather than reducing weight
When It May Not Suit
- Significant skin laxity, jowls or neck bands that need lifting
- A plan to lose a large amount of weight soon
- Bleeding disorders, uncontrolled diabetes or heart or lung conditions
- Pregnancy, or pregnancy planned in the near future (for body areas)
Safe Volume Limits
The amount of fat removed in one session is limited for safety, not only for appearance. Removing large volumes shifts body fluids, increases blood loss and raises the amount of local anesthetic absorbed into the body. Many professional guidelines treat removing more than about 5 liters of total aspirate (fat and fluid) in one session as large-volume liposuction, which calls for additional monitoring and often an overnight stay.
The local anesthetic in tumescent fluid also has a maximum safe dose based on body weight. When many areas need treatment, it is often safer to stage them over separate sessions than to treat everything at once. Combining extensive liposuction with other major operations on the same day also increases risk, so the overall length and scope of surgery is planned with safety first.
Face and neck liposuction involves much smaller volumes, but the same principles apply: careful dosing, gentle technique and leaving enough fat to keep the contour smooth.
Compression Garments
After body liposuction, a compression garment is usually worn for several weeks. After face and neck liposuction, a chin strap or face band is commonly worn, often full time at first and then mainly at night. Compression helps limit swelling and fluid collection and supports the skin as it settles.
The garment should be snug but not painful. Marks, numbness that worsens or skin color changes under the garment should be reported. The exact type and duration are given in your aftercare instructions.
Anesthesia and Incisions
Small single areas are commonly treated under tumescent local anesthesia, sometimes with sedation. Multiple or larger areas may be done under sedation or general anesthesia. The choice depends on the extent of treatment and your health.
Incisions are a few millimeters long and placed in natural creases, under the chin, behind the earlobes, in the navel or the bikini line where possible. They usually fade over months but can darken for a while, especially in people prone to pigmentation.
Recovery Timeline
| Timing | Typical course |
|---|---|
| First 1–2 days | Tumescent fluid may leak from the incisions; this is expected. Soreness, tightness and swelling are common. Walking gently early on helps circulation. |
| About 1 week | Small stitches, if used, are commonly removed. Bruising is fading. Many people return to desk work, especially after face or small-area treatment. |
| 2–4 weeks | Swelling decreases steadily. Light exercise is usually resumed; strenuous exercise waits until you are cleared. |
| 1–3 months | The treated area may feel firm, lumpy or numb as tissue heals. Gentle massage or care may be advised. |
| 3–6 months and beyond | Swelling settles and the contour becomes clearer. Skin adapts over this period; the final result is usually judged after several months. |
Recovery varies with the number of areas treated, the volume removed and individual healing.
Risks
- Contour irregularities Dents, ripples or uneven areas, especially where fat was removed too close to the skin or unevenly.
- Asymmetry The two sides may differ slightly.
- Seroma Fluid collecting under the skin, which may need to be drained.
- Loose skin Skin may not shrink enough over the new contour, particularly in older or thinner skin.
- Numbness and altered sensation Usually improve over months.
- Skin discoloration and burns Pigment changes can occur; energy-assisted devices carry a risk of burns.
- Nerve injury Around the jawline, temporary lower lip weakness is possible.
Rare but Serious Complications
- Infection Uncommon but can be serious; spreading redness, fever or increasing pain needs prompt attention.
- Blood clots Clots in the leg veins can travel to the lungs. Early walking and risk assessment help reduce this.
- Fat embolism Fat entering the bloodstream and affecting the lungs or brain. It is rare but can be life-threatening.
- Local anesthetic toxicity and fluid imbalance Related to the dose of local anesthetic and the volume removed, which is why limits are set.
- Injury to deeper structures Very rarely, a cannula can injure deeper structures such as the abdominal wall.
Shortness of breath, chest pain, confusion or calf swelling after surgery require emergency care.
Combining with Other Procedures
Face and neck liposuction is often combined with a mini facelift or facelift when both excess fat and sagging are present. Liposuction refines the fat layer, while lifting repositions tissue and removes loose skin.
Skin tightening treatments such as Ulthera or Thermage are sometimes considered for mild laxity, although they cannot match the effect of removing skin. Where the face has lost volume rather than gained fat, removing fat is the wrong direction; volume-restoring treatment such as Sculptra may be discussed instead.
For those also considering eyelid surgery, see the eyelid surgery overview. Whether procedures can safely be done on the same day depends on the total scope of surgery.
Frequently Asked Questions
Is liposuction a way to lose weight?
No. Liposuction removes localized fat to improve shape. It is best for people at or near a stable weight. Weight on the scale may change little, even when the contour changes noticeably.
Can fat come back after liposuction?
The fat cells removed do not return. However, remaining fat cells can grow with weight gain, in treated or untreated areas. Keeping a stable weight helps maintain the result.
Will liposuction tighten my jawline if my skin is sagging?
Liposuction does not lift sagging tissue. If jowls or loose neck skin are the main concern, a mini facelift or facelift is usually needed, sometimes combined with neck liposuction.
How much fat can be removed at once?
It depends on your body size, health and the areas involved. Many professional guidelines treat more than about 5 liters of total aspirate in one session as large-volume liposuction that needs additional precautions. Staging treatment is often safer when many areas are planned.
How long do I need to wear a compression garment?
For body areas it is usually worn for several weeks. For the face and neck a chin strap is commonly worn full time at first and then mainly at night. Your aftercare instructions give the exact duration.
Are laser or ultrasound devices better than standard liposuction?
Not necessarily. Energy-assisted devices can help in dense or fibrous fat, but they add heat-related risks such as burns. The surgeon's technique and judgment matter more than the device name.
Why does the treated area feel lumpy or numb?
Firmness, small lumps and numbness are common during healing as swelling resolves and tissue settles. They usually improve over weeks to months. Persistent or worsening changes should be checked.
When will I see the final result?
An early change is often visible within weeks, but swelling settles gradually. The final contour is usually judged after several months.
