LAMS vs Fat-Dissolving Injections: Removal or Dissolving?

Key takeaway: The choice comes down to taking fat out versus asking your body to clear it. LAMS extracts fat directly in a single numbed session, so it suits moderate pockets where you want a clear change in one visit. Fat-dissolving injections break fat down gradually over several sessions and suit smaller areas or touch-ups. If you have limited time in Korea and a defined area of stubborn fat, LAMS is often the more practical route; if the area is small and you can return, injections may be enough.

Both options are marketed as "minimally invasive", which makes them easy to confuse. The real difference is mechanical: one takes fat out, the other asks your body to clear it. This guide sets out how that difference affects results, recovery and planning.

How each approach works

LAMS: removal

LAMS (Local Anesthetic Minimal-Invasive Liposuction), which 365mc introduced in 2014, needs nothing more than local numbing, and you are conscious from start to finish. It has three stages:

1. Tunnelling to loosen the fibrous bands that hold fat in place.
2. Extraction, in which a fine cannula removes fat through a tiny opening.
3. A dissolving solution to help clear remaining nearby fat.

You can read more on the LAMS page.

Injections: dissolving

Fat-dissolving injections place a solution into the fat layer. Deoxycholic acid (DCA), used in the O-Slim Shot, breaks down fat-cell membranes. Hypotonic solutions such as HPL draw water into fat cells by osmotic pressure so they swell and break down. In both cases, your body clears the treated fat over the following weeks.

Which gives a bigger change?

Because LAMS physically removes fat, it usually achieves a more noticeable contour change in a single session than injections. Injections tend to produce gradual, modest change, and several sessions are common.

• Small pocket under the chin or along the jaw: injections may be enough; facial LAMS is an option if fullness is more pronounced.
• Moderate pocket on the arms, lower belly or flanks: LAMS is often more efficient; injections may need many sessions.
• Several areas or larger volume: Infinite LAMS or conventional liposuction is usually considered rather than injections.
• Fine-tuning after a procedure: injections can be useful once healing has settled.

Both share the same limits: they do not reach visceral fat (fat around the organs), they do not tighten loose skin, and neither will noticeably lower your weight.

Sessions, downtime and recovery compared

LAMS

• Usually one procedure per area.
• Only the area is numbed, and most people leave on their own feet the same day.
• Swelling and bruising are possible and settle over days to weeks.
• No compression garment is required for LAMS.
• Aftercare may include shockwave therapy (ESWT) as part of the Orange Care programme.

Fat-dissolving injections

• Multiple sessions: O-Slim Shot sessions take around 10–20 minutes; HPL sessions around 30–40 minutes, roughly 7–10 days apart.
• No anaesthesia; most people resume normal activities the same day.
• Swelling, tenderness and bruising are common; HPL may also cause fluid drainage, increased urination or mild dizziness for about a day.

Risks and side effects, stated plainly

With LAMS, risks include bruising, swelling, temporary numbness, small irregularities in contour, minor scarring at the entry point, infection and, rarely, more serious complications. Being awake under local anaesthesia avoids the risks specific to general anaesthesia, but it is still a medical procedure.

With injections, risks include swelling, burning or stinging, bruising, firm nodules, uneven results and, for facial areas, temporary nerve irritation. Product quality and placement are important, so ask exactly what is being injected.

Whichever you lean towards, your health background and medicines should be checked first, and you should feel free to ask how complications are handled. The safety and risks page covers this in more depth.

Who may suit each option?

LAMS may suit you if

• You have a defined, moderate area of stubborn fat and want a clear change in one visit.
• You would like to avoid general anaesthesia.
• You have a limited window in Korea.
• You are in reasonable general health and near a stable weight.

Injections may suit you if

• The area is small and you are happy with a gradual, subtle result.
• You would prefer not to have any procedure involving a cannula.
• You can schedule several sessions, either during a longer stay or across trips.
• You want to refine an area after LAMS or liposuction.

Combining the two

Many plans use both: LAMS to remove the main volume, then injections for small residual areas. When the same area is treated with both, a gap of around four to six weeks is generally advised.

What shapes the cost of each?

Expect a personal quote for either option, since Korean law limits how clinics advertise prices for uninsured treatments. At 365mc, a given treatment is priced identically at each of its hospitals.

• LAMS is charged by the "bottle" of fat removed, so how much fat the area holds drives the figure.
• Injections depend on the product, the amount used per session and the number of sessions.
• For injections, a low per-session price can add up over a long course, so compare the total plan.

Either way, ask whether the fees qualify for the tourist VAT refund before you pay.

Planning either option around a trip to Korea

• Short stay (under a week): LAMS is often more practical, as it needs one procedure. Injections may only allow one session in this time.
• Longer stay (two to three weeks): you could fit several HPL sessions, or LAMS plus some aftercare sessions.
• Aftercare abroad: after LAMS, overseas patients have six months to use their aftercare sessions at the treating branch, with at-home guidance and message-based check-ins covering any they miss.

Questions patients often ask

Is LAMS just a stronger injection?

No. LAMS takes fat out mechanically and then applies a solution to help clear what is left nearby. Injections rely only on a solution and your body's clearance.

Which has less downtime?

Injections usually have less downtime per session, though swelling can be noticeable. LAMS has a shorter recovery than conventional liposuction but still involves some swelling and bruising.

Can injections replace LAMS for my belly?

For a small lower-belly pocket, possibly. For a larger area, injections may need many sessions and still achieve less. A doctor can advise after examining you.

Do I need a compression garment after either?

No compression garment is required for LAMS, and injections do not normally need one. Conventional liposuction does use one.

Can fat return after either treatment?

Neither method lets treated fat cells return, yet untreated cells can still enlarge if your weight goes up, so steady habits protect either result.

If you cannot decide between removal and dissolving for your area, you can get a doctor's view on LAMS or injections. Share photos and your travel dates in an online or video consultation, and the plan can be matched to the time you have in Korea.
