Liposuction is a cosmetic surgery procedure that removes fat from the body. It is often performed on areas such as the hips, belly, thighs, buttocks, back, arms, neck, and face. Liposuction can be done in a hospital or a surgeon's office, depending on the amount of fat being removed. During the procedure, a surgeon will make small incisions in the skin and insert a suction device attached to a cannula, a small stainless-steel instrument, to break up and remove fat. The fat cells are permanently removed during liposuction, but weight can still be gained back in different areas of the body. In addition to liposuction, there are also non-invasive fat removal methods that use injections or handheld devices to destroy fat cells without making incisions.

What You'll Learn

Liposuction
During the procedure, the surgeon will make small incisions in the skin and insert a suction device attached to a thin tube called a cannula. The cannula is moved back and forth to break up or liquefy the fat, which is then suctioned out. The most common type of liposuction is tumescent liposuction, which involves injecting a sterile solution into the area before fat removal to reduce blood loss, bruising, and swelling. Other types of liposuction include ultrasound-assisted liposuction (UAL), which uses sound wave energy to liquefy the fat, and laser-assisted liposuction (SmartLipo).
It is important to note that liposuction is an invasive procedure with associated risks, including blood clots and weight gain after surgery. It is not suitable for everyone, and individuals should consult with a specially trained and qualified surgeon to ensure they are good candidates for the procedure.

Non-invasive fat removal
During the procedure, a dermatologist uses either a handheld device or injections to destroy and permanently remove fat cells without making any incisions. The injections contain an acid similar to bile acid, which helps the body digest fat. The U.S. Food and Drug Administration (FDA) has approved several handheld devices and injections for this purpose. These treatments can be safely performed by a licensed, trained aesthetician under physician supervision.

Buccal fat removal
During the procedure, the patient is given a local anaesthetic to numb the skin on their face, although general anaesthesia may be used if other procedures are being performed simultaneously. The surgeon makes a small incision on the inside of the mouth on both sides of the face to expose and remove the buccal fat pads, before closing the incisions with sutures. The amount of fat removed depends on the desired facial shape.

Fat freezing
During the procedure, a cryolipolysis device is used to cool the targeted fat to a temperature that destroys it while leaving the skin and other tissues unharmed. The device holds the treatment area between two paddles, which are left in place for about 35 minutes to 1 hour and 15 minutes. This process destroys approximately 10% to 25% of the fat cells in the targeted area. The body then naturally eliminates these dead fat cells over time, resulting in a gradual reduction of fat.
CoolSculpting is particularly effective for treating visible fat bulges in various areas of the body, including the submental (under the chin) and submandibular (under the jawline) regions, thighs, abdomen, flanks (love handles), bra fat, back, and upper arms. It is important to note that CoolSculpting is not a weight-loss treatment and does not affect visceral fat, which is located deeper inside the body.
While CoolSculpting is generally considered safe, it may cause side effects such as swelling, bruising, or discomfort. In rare cases, fat freezing can lead to long-term pain or an increase in fat in the treated area. It is important to consult with a qualified healthcare provider to determine if CoolSculpting is suitable for your specific needs and to ensure a safe and effective treatment process.

Fat dissolving injections
The injections contain an acid similar to bile acid, which is the substance that allows our bodies to digest fat. Like bile acid, the acid in these injections dissolves fat cells, resulting in permanent fat reduction.
It is important to note that only a prescription drug called Kybella, the brand name for deoxycholic acid, is FDA-approved for fat reduction under the chin. Unapproved fat-dissolving injections may cause adverse reactions such as permanent scars, serious infections, skin deformities, cysts, and deep, painful knots. Therefore, it is crucial to consult a licensed healthcare professional before undergoing any fat-dissolving injection treatment.

Frequently asked questions
The fat is suctioned out of the body through a small, hollow tube called a cannula. The fat cells are permanently removed during liposuction, but new fat cells can develop and gain weight.
The fat is removed from the body and disposed of as medical waste.
Non-invasive fat removal treatments use injections or handheld devices to destroy fat cells. The targeted fat cells are gone forever, but remaining cells can expand if weight is gained.
Buccal fat removal surgery reduces fullness in the face and highlights cheekbones. The fat pads are cut and removed through small incisions on the inside of the mouth.
