Fat dissolving injections are for stubborn pockets, not for the scales — and that distinction matters.

Where can I get fat dissolving injections on Koh Samui? Fat dissolving (lipolysis) injections are available at licensed, doctor-led clinics such as LIV Clinic, where an injectable such as deoxycholic acid is used to break down small, stubborn pockets of fat — most commonly under the chin.

What fat dissolving injections are

Injectable fat reduction

A solution is injected into a small pocket of fat to break down the fat cell membranes, after which the body clears the released contents naturally.

Deoxycholic acid

MedlinePlus describes deoxycholic acid injection as used to improve the appearance of moderate to severe submental fat — the double chin — working by breaking down cells in fatty tissue.

What they treat

They suit small, localised pockets rather than large areas:

• Under the chin (submental fat) — the most established use
• Small pockets along the jawline
• Localised areas some clinics treat off-label
• Stubborn fat that resists diet and exercise
• Areas where surgery feels excessive

What they are not

Not a weight-loss treatment

They reduce small localised pockets. They do not reduce body weight and are no substitute for diet and activity.

Not for loose skin

If the concern is laxity rather than fat, skin tightening is the appropriate route — and significant laxity may need surgery.

Sessions and protocol

*Per MedlinePlus guidance for deoxycholic acid; your plan is confirmed at consultation.

What to expect afterwards

Swelling is expected

Noticeable swelling in the treated area is normal and part of how the treatment works. It can last several days and occasionally longer.

Other common effects

Bruising, tenderness, firmness and temporary numbness in the area are common and settle over time.

Are results lasting?

Treated fat cells are destroyed

Once fat cells are broken down they do not return, so results are lasting provided your weight stays stable.

But weight gain still shows

Remaining fat cells elsewhere can enlarge with weight gain, so a stable weight protects your result.

Why it must be doctor-led

Anatomy and placement

Injecting into the wrong tissue plane can cause problems, particularly near the jawline where nerves run — which is why this belongs in a medical clinic.

Candidate selection

Assessment determines whether your concern is genuinely fat, and whether you are a suitable candidate at all.

Preparing for and recovering from treatment

Preparation and aftercare:

1. Have a consultation so Dr. Narathai can confirm the concern is fat, not laxity.
2. Disclose your medical history and medications.
3. Plan for visible swelling for several days afterwards.
4. Avoid alcohol and blood-thinning supplements for 24–48 hours before, where appropriate.
5. Avoid heat, saunas and heavy exercise for the first day.
6. Allow 4–12 weeks per session before judging results.
