Key takeaways
- Body contouring is not weight loss: liposuction is not a treatment for obesity or a substitute for diet and exercise, according to ASPS.[1]
- The CoolSculpting System is FDA cleared to affect the appearance of visible fat bulges, in most body areas for people with a BMI of 30 or less.[3]
- Kybella is FDA approved only for moderate to severe fat under the chin in adults.[4]
- Across studies reviewed in 2015, cryolipolysis reduced the treated fat layer by roughly 10% to 28%, with mostly mild, short-lived side effects.[5]
In short: Body contouring changes the shape of specific areas, either without surgery (for example fat freezing, heat-based devices or fat-dissolving injections) or with surgery (liposuction, tummy tuck and lifts). It is not weight loss and not a treatment for obesity: these treatments reduce or remove fat in one area, or remove loose skin, and, in the case of liposuction, the American Society of Plastic Surgeons says it works best for people near their ideal weight. If your goal is to lose weight for your health, start with how to lose weight.
Contouring is not weight loss. The American Society of Plastic Surgeons states that liposuction is not a treatment for obesity or a substitute for diet and exercise. The FDA clearance for the best-known fat-freezing device describes it as affecting the appearance of visible fat bulges, for people with a BMI of 30 or less in most body areas.
This hub compares non-invasive and surgical options, explains what each can and cannot do, and covers downtime, cost and how to choose a provider. It is general information; a board-certified plastic surgeon or dermatologist can tell you what fits your body and goals.
Start here: do these next 1-2-3
- Name your goal. Weight and health: lose weight. Shape of one area: keep reading. Loose skin after weight loss: loose skin. Building a stronger, leaner look: body recomposition.
- Think about timing. If you are still losing weight, ask a specialist how further weight changes would affect a contouring result.
- See a qualified specialist for an in-person assessment before paying for a package of sessions.
Weight loss, contouring and recomposition: three different things
Weight loss lowers total body fat and improves health markers; it happens through eating, activity, medicine or bariatric surgery, and you cannot choose where the fat comes off. Body contouring reshapes chosen areas; the number on the scale barely moves. Body recomposition means losing fat and gaining muscle at the same time through training and nutrition. Our shape and look better hub explains how the three fit together.
Non-invasive and surgical options compared
| Option | How it works | Type | What to know |
|---|---|---|---|
| Cryolipolysis (“CoolSculpting”) | Controlled cooling breaks down fat cells under the skin | Non-invasive device | FDA cleared to affect the appearance of visible fat bulges in specific areas |
| Radiofrequency and laser fat reduction | Heat targets fat cells | Non-invasive device | Named by ASPS among nonsurgical fat-reduction options |
| Muscle stimulation | Devices that make muscles contract | Non-invasive device | Aimed at muscle tone; see its page for the evidence |
| Kybella (deoxycholic acid) | Injected drug that destroys fat cells | Prescription injection | FDA approved only for fat under the chin in adults |
| Liposuction | Fat is suctioned out through small incisions | Surgery | Not a treatment for obesity; best for people near their ideal weight with localized fat |
| Tummy tuck, breast lift and other lifts | Remove loose skin and tighten tissue | Surgery | For loose skin, for example after large weight loss; surgical recovery and scars |
| Skin tightening | Energy devices aimed at mild laxity | Non-invasive device | See its page for what the evidence shows |
Non-invasive fat reduction: what to expect
The American Society of Plastic Surgeons lists four main nonsurgical approaches: cryolipolysis (cooling), injection lipolysis such as Kybella, radiofrequency lipolysis and laser lipolysis, and says none of them is a replacement for liposuction. They are for people who cannot or do not want to have surgery, and ASPS says people who are pregnant or breastfeeding should not have them.
Cryolipolysis. The CoolSculpting System’s FDA clearance (510(k) K193566, 2020) covers cold-assisted breakdown of fat in areas such as the upper arm, back, thigh, abdomen and flanks in people with a BMI of 30 or less, and under the chin and jaw in people with a BMI up to 46.2. A 2015 review in Plastic and Reconstructive Surgery found fat-layer reductions of roughly 10% to 28% in the treated area across studies, with mostly mild, short-lived side effects such as redness, swelling and pain. A rare complication, paradoxical adipose hyperplasia, makes the treated area grow larger instead of smaller.
Kybella. The FDA label approves deoxycholic acid injections only to improve the appearance of moderate to severe fullness from fat under the chin in adults, and says it is not approved for fat elsewhere. In its trials, about 70% of treated people improved by at least one grade versus 18% on placebo. The label warns about nerve injury in the jaw that can cause an uneven smile and about trouble swallowing; swelling, bruising, pain and numbness are common. See also double chin.
Surgical contouring
ASPS describes liposuction as surgery that removes fat from areas such as the abdomen, thighs, hips, chest, arms, neck and back, and says it works best for people at or near a normal weight with firm, elastic skin; people with loose skin, for example after large weight loss, tend to get better results from skin-removal surgery such as a tummy tuck or lift. Surgical contouring involves anesthesia, incisions, scars and a recovery period, and carries surgical risks. Comparisons: liposuction vs cryolipolysis and tummy tuck vs liposuction.
Who contouring may suit
The sources point the same way. ASPS describes the best liposuction candidates as people at or near a normal weight with localized fat and firm, elastic skin. The CoolSculpting clearance limits most body areas to people with a BMI of 30 or less. Kybella is approved only for fat under the chin. And ASPS says people who are pregnant or breastfeeding should not have nonsurgical fat reduction. If you are still working on your weight, the most useful next step is usually our weight-loss hub; contouring can be a later conversation.
Downtime
Non-invasive treatments involve no incisions. For cryolipolysis, the 2015 review found mainly mild, short-lived side effects such as redness, swelling and pain; for Kybella, the label lists swelling, bruising, pain and numbness at the injection site. Surgical contouring involves anesthesia, incisions and a recovery period with follow-up visits. Each procedure page gives its recovery details from its sources, and your provider can tell you how much time off to plan.

Cost and insurance
Cosmetic contouring is generally paid out of pocket, and non-invasive treatments are often sold as packages of several sessions. Ask for an all-inclusive written quote that lists each session or each part of a surgery (surgeon, anesthesia, facility, garments and follow-up). We publish prices only with a source and a date; see tummy tuck cost and our costs hub, which also explains the risks of medical credit cards.
Choosing a provider
For surgery, choose a surgeon certified by the American Board of Plastic Surgery who operates in an accredited facility. For devices and injections, ask who performs the treatment and who supervises it, which FDA-cleared or FDA-approved product is used, how many treatments they have done, what results are realistic for your body, and how complications such as paradoxical fat growth or nerve injury are handled. Be wary of before-and-after photos without context and of promises about results. Our guide to plastic surgeons explains how to check credentials.

Frequently asked questions
Does body contouring help you lose weight?
No. Contouring reshapes specific areas; it is not a weight-loss method or a treatment for obesity. Weight loss comes from eating, activity and, when appropriate, medical treatment.
What is the best non-surgical body contouring?
There is no single best option. Cryolipolysis, radiofrequency, laser and injection treatments each suit different areas and goals, and none replaces liposuction, according to ASPS. A specialist can assess what fits you.
Is CoolSculpting permanent?
It breaks down fat cells in the treated area. Ask your provider how later weight changes could affect the result. A rare complication, paradoxical adipose hyperplasia, makes the treated area larger instead of smaller.
Who is a good candidate for liposuction?
ASPS says people at or near a normal weight with localized fat and firm, elastic skin. People with loose skin may get better results from skin-removal surgery.
Does insurance cover body contouring?
Cosmetic contouring is generally paid out of pocket. If you are considering skin-removal surgery after large weight loss, ask your plan in writing whether any part could be covered.
