Submental fullnessโbetter known as the โdouble chinโโand neck laxity are among the most common cosmetic concerns for both men and women. Even healthy people with a normal body weight can struggle with stubborn fat and sagging skin beneath the chin.
The good news: there are multiple treatment options, ranging from injectables and devices to surgery. But not all approaches are created equal. And importantlyโnot all providers offer the full menu of treatments, which can bias their recommendations. If a clinic only offers Kybella, CoolSculpting, or Morpheus8, guess what theyโll recommend?
Hereโs a full comparison of Kybella, CoolSculpting, Morpheus8, liposuction, and neck lift surgery, with pros, cons, and real-world satisfaction ratings.
1. Kybella (Deoxycholic Acid Injections)
What it is: An FDA-approved injectable that dissolves fat cells under the chin using deoxycholic acid.
Pros:
- Non-surgical, in-office procedure.
- Permanently destroys fat cells.
- FDA-approved for double chin.
Cons:
- Requires multiple sessions (2โ4+).
- Swelling (โbullfrog effectโ) for 1โ2 weeks each time.
- Can be more expensive than surgery over multiple sessions.
- Does not tighten skin.
- Lowest satisfaction rate of all options. Many patients feel the cost, swelling, and downtime donโt match the results.
Best for: A very select group of patients with minimal fat and tight skin who refuse surgical options.
Worth It Rating: ~65% (lowest of all options)
2. CoolSculpting (Cryolipolysis)
What it is: A non-invasive device that freezes fat cells, which are cleared by the body over several weeks.
Pros:
- Non-invasive, no needles.
- Little to no downtime.

Cons:
- Results are subtle and sometimes unpredictable.
- May require multiple sessions.

Best for: Patients with small, well-defined fat pockets under the chin who want zero downtime.
Worth It Rating: ~70%
3. Morpheus8 (Radiofrequency Microneedling)
What it is: A minimally invasive device that combines microneedling with radiofrequency energy to stimulate collagen and tighten skin. On the neck and jawline, it can improve laxity and mild contour issues.
Pros:
- Stimulates collagen and elastin for firmer skin.
- Improves texture, tone, and mild sagging.
- Minimal downtime compared to surgery.
- Can be combined with liposuction for enhanced results.
Cons:
- Multiple sessions needed for best results.

- Risk of burns, pigmentation changes, or uneven results if performed improperly.
- Maintenance required every 12โ18 months.
Best for: Patients with mild to moderate laxity who want a non-surgical skin tightening option.
Worth It Rating: ~80%
4. Chin/Neck Liposuction
What it is: A surgical procedure that removes fat through a small incision under the chin.
Pros:
- Direct removal of fat in a single session.
- Immediate, noticeable results.
- Relatively short recovery (3โ5 days back to work).
- Often less expensive long-term than repeated nonsurgical treatments.
Cons:
- Requires anesthesia and small incisions.
- Bruising and swelling for 1โ2 weeks.
- Does not tighten loose skin.
Best for: Patients with good skin tone and moderate fat deposits seeking a one-time solution.
Worth It Rating: ~85โ90%
5. Neck Lift Surgery
What it is: A surgical procedure that removes excess skin, tightens muscles, and improves contour. Often combined with liposuction.
Pros:
- Most powerful option for sagging skin and muscle bands.
- Long-lasting (10+ years).
- One procedure, no repeat sessions.
- Comprehensive improvement in contour.
Cons:
- Invasive, with anesthesia and incisions.
- 1โ2 weeks of downtime.
- Higher upfront cost.
- Surgical risks (scarring, nerve injury, infection).
Best for: Patients with significant skin laxity and aging changes, often in their 40sโ60s+.
Worth It Rating: ~90% (highest satisfaction)
Why It Matters Who You See
A clinic that only offers Kybella, CoolSculpting, or Morpheus8 will naturally steer you toward those treatmentsโeven if youโd be a better candidate for liposuction or a neck lift. This is a classic case of โif the only tool you have is a hammer, everything looks like a nail.โ
The best choice is a provider who can offer both non-surgical and surgical options, and tailor a plan based on your anatomy, goals, and tolerance for downtime.
Bottom Line
- Kybella: The worst choice overallโlowest satisfaction, high swelling, multiple sessions, and cost that rivals surgery.
- CoolSculpting: Non-invasive, but results are subtle and inconsistent.
- Morpheus8: Great for skin tightening and texture, but not fat removal; best for mild laxity.
- Liposuction: Best one-time fix for stubborn fat with good skin tone.
- Neck Lift: Gold standard for sagging skin, muscle bands, and aging changesโhighest satisfaction and most dramatic results.
The smartest move? Choose a provider who offers all five options, so you know youโre getting advice based on your needsโnot their limited toolbox.
