Fat-Dissolving Injections in Seomyeon, Busan
Fat-dissolving injections (지방분해주사) are injections into small, localised fat pockets, such as under the chin, jawline, upper arms or abdomen, designed to break down fat cells. Approved products contain deoxycholic acid; many clinics also use other lipolysis formulas. In Seomyeon, Busan, a session takes about 15–30 minutes. Most people need 2–4 or more sessions several weeks apart, with swelling for a few days after each.

What are fat-dissolving injections?
These treatments inject a substance directly into fat to damage fat cell membranes, after which the body gradually clears the debris. Deoxycholic acid, a synthetic version of a natural bile acid, is the best-studied ingredient and is approved in several countries for fat under the chin. In Korea, many clinics offer their own lipolysis "cocktails" (sometimes called contour or slimming injections) containing different ingredients for face and body; their composition and evidence vary, so it is important to ask exactly what is being injected.
Who is it for?
- People near a stable, healthy weight with a small, pinchable fat pocket
- Those wanting a non-surgical alternative to small-area liposuction
- People with mild double chin or jowl fat and good skin elasticity
It is not a weight-loss treatment and is unsuitable for large areas, loose skin or fat that lies deep beneath muscle. Pregnancy, breastfeeding, infection at the site or certain medical conditions are reasons to avoid it.
What happens at the clinic
- Assessment: the doctor checks whether the bulge is fat (not muscle, gland or loose skin).
- Product discussion: ingredient, approval status and expected number of sessions.
- Marking: a grid is drawn over the treatment area.
- Injection: multiple small injections, with numbing or ice for comfort.
- Follow-up: review before the next session to judge response.
Recovery and aftercare
Swelling, redness, tenderness and numbness are expected, especially with deoxycholic acid under the chin, where swelling can be noticeable for several days. Cold packs help. Avoid massage unless instructed, and plan sessions around social events. Results appear gradually over weeks, and fat cells destroyed do not regrow, though remaining cells can enlarge with weight gain.
Risks and side effects
- Swelling, bruising, pain and firmness
- Temporary numbness
- Uneven results or small lumps
- Under the chin: rare marginal mandibular nerve injury causing an uneven smile, usually temporary
- Skin injury or infection if injected incorrectly; unknown long-term effects with unregulated formulas
Choosing a clinic for fat-dissolving injections in Seomyeon
- Ask exactly which product and ingredients are used and whether it is approved.
- Choose a physician who checks whether fat, not skin laxity, is the problem.
- Ask how many sessions are realistic and the interval between them.
- Ask about nerve safety zones for jawline treatments.
- Be cautious about "weight-loss" claims for injections.

Frequently asked questions
Do fat-dissolving injections really work?
Deoxycholic acid has good evidence for reducing small fat pockets, especially under the chin, over several sessions. Evidence for other clinic formulas varies. None are designed for overall weight loss.
How many sessions of fat-dissolving injections do I need?
Most people need 2–4 sessions or more, depending on the area and product. Deoxycholic acid sessions are usually spaced about 4–8 weeks apart to allow swelling to settle and results to develop.
How long does swelling last after fat-dissolving injections?
Swelling and tenderness are common for several days, and under-chin swelling can last up to about a week or two. Numbness may persist a little longer.
Fat-dissolving injections vs liposuction: which is better?
Injections avoid surgery but need multiple sessions and suit small areas. Liposuction removes more fat in one procedure with more downtime. The best choice depends on the amount of fat and your preferences.
Can fat come back after fat-dissolving injections?
Destroyed fat cells do not return, but remaining fat cells can enlarge if you gain weight. Maintaining stable weight helps keep results.
