What Is a Double Chin?

A double chin (submental fullness) is a full contour under the chin, usually caused by fat, loose skin or both.

Deoxycholic acid is the only injectable drug the US FDA has approved for fat under the chin, sold as Kybella and as a generic; it has also been authorised as Belkyra in Canada and several European countries. In two trials of more than 1,000 adults, 66.5–70% improved by at least one grade on both clinician and patient ratings, against 18.6–22.2% on placebo.

Aqualyx, a deoxycholate-based solution, has been marketed in Europe as a CE-marked medical device rather than a licensed medicine. The FDA warns against unapproved fat-dissolving injections such as Aqualyx, Lipo Lab and Kabelline, citing serious infections, scarring and painful knots; in 2025 it called LemonBottle an unapproved drug.

Double Chin Treatment Options

Method	How it works	Usually suits
Injection lipolysis	Injected deoxycholic acid or deoxycholate destroys fat cells	Moderate to severe fat; skin not very loose
Morpheus8 RF microneedling	Radiofrequency heat through fine needles tightens tissue and remodels collagen	Loose skin with little fat
HIFU	Focused ultrasound heats deeper layers through intact skin	Mild to moderate laxity of the chin and neck
Cryolipolysis	A small vacuum applicator cools the fat for up to about an hour	Pinchable fat; no needles
Liposuction (surgery)	Fat is suctioned through small incisions, often under local anaesthesia	Larger fat volumes in one procedure

What Causes a Double Chin

Fat in front of the platysma: the layer injections and cryolipolysis treat.
Weight gain, ageing and genetics: after treatment, remaining fat cells can still enlarge.
Loose skin: in trials, laxity was unchanged or improved in most patients, but very loose skin can look worse after fat loss.
Anatomy: platysmal bands or drooping submandibular glands.
Medical causes: an enlarged thyroid or lymph nodes, which a doctor must rule out first.

Who It Suits — and Who Should Wait

Injections: adults with moderate to severe fullness from fat and skin that is not very loose.
Tightening devices: mild to moderate loose skin with little fat.
Surgery: large fat volumes, marked laxity or prominent bands.
Postpone during pregnancy or breastfeeding, or with an infection in the area.
Mention swallowing problems, bleeding disorders, blood thinners or earlier treatment under the chin.
Darker skin: deoxycholic acid trials included skin types I–VI; RF microneedling can cause temporary darkening, so its settings are lowered, while this is uncommon after HIFU.

How the Treatment Works at Veneta

Assessment

A physician examines fat, skin, bands and swallowing history, rules out other causes and recommends a method.

Marking and numbing

For injections, a 1 cm grid is marked; ice, numbing cream or a local anaesthetic can improve comfort.

Treatment session

Small amounts are injected into the fat with a fine needle; pain or burning, swelling and numbness are common afterwards.

Aftercare and follow-up

Cold packs can ease discomfort. Report difficulty swallowing, an uneven smile or a lasting lump. Sessions are at least 1 month apart.

Results to Expect and Other Options

Injection results build over weeks; in trials they were assessed 12 weeks after the last session.

Device evidence is smaller. Single studies found cryolipolysis thinned fat under the chin by 2.0 mm on average (60 people, 2016), RF microneedling improved the lower face, jawline and neck (30 patients, 2022) and microfocused ultrasound improved the chin and neck in 68.6% of 70 patients at 3 months. Cryolipolysis can also, rarely, enlarge treated fat (paradoxical adipose hyperplasia).

Frequently Asked Questions

How many double chin injection sessions are needed?

Deoxycholic acid double chin injections typically take 3–6 sessions, according to the American Society for Dermatologic Surgery, given at least 1 month apart; the manufacturer reports visible results after 2–4 in many trial patients.

How long does swelling last after double chin injections?

After deoxycholic acid double chin injections, the most noticeable swelling usually lasts 5–14 days, according to the American Society for Dermatologic Surgery; in trials, numbness lasted over a month in 42% of patients and swelling in 20%.

Do double chin injections hurt, and what are the risks?

Deoxycholic acid double chin injections commonly cause pain or burning (70% of trial patients reported pain), swelling, bruising and numbness. In trials, temporary nerve injury with an uneven smile affected 4% and swallowing difficulty 2%; all resolved. Skin ulcers have been reported, and in 2026 the FDA warned that lumps may persist and need treatment.

Do double chin injection results last?

Deoxycholic acid double chin injections destroy the treated fat cells. In a 2021 three-year follow-up of 224 trial patients, most responders (82.4%) kept their result at year 3; weight gain can still enlarge the remaining fat cells.

Double chin injections or liposuction: which is better?

Double chin injections with deoxycholic acid avoid surgery but take several sessions; liposuction removes more fat in a single procedure, often under local anaesthesia, followed by about a week in a compression wrap.

Is Kybella available in Turkey?

Kybella is the US brand of deoxycholic acid, the only FDA-approved injectable drug for fat under the chin; the same drug has been authorised as Belkyra in Canada and several European countries. A Turkish licence for either is not publicly documented, so ask which product will be injected and whether it is licensed in Turkey.
