Fat-dissolving injections are one of the most popular non-surgical slimming procedures in Korea, especially for small areas like the double chin, jawline, arms, bra bulge, and belly pouch. But one of the most common questions international patients ask is:
“How many sessions do I actually need?”

Here’s a clear, realistic breakdown of how many treatments to expect, how fast results appear, and what determines the session count.

1. Typical Number of Sessions in Korea

Most patients need:

➡ 2 to 4 sessions

for visible and lasting reduction.

However, depending on the area, formula strength, and fat volume, it can range from:

• 1–2 sessions for very small areas (double chin, jawline)
• 3–5 sessions for moderate pockets (lower abdomen, muffin top)
• 4–6 sessions for stubborn areas or thicker fat layers

Korean dermatologists usually recommend sessions every 1–2 weeks for faster results.

2. Sessions Needed by Body Area

Double Chin / Jawline

2–3 sessions
Most patients see a noticeable V-line improvement by the second treatment.

Arms (Upper Arm Fat)

3–4 sessions
Arm fat tends to be stubborn and often requires more rounds.

Lower Belly Pouch

3–5 sessions
Small but dense fat areas usually need multiple rounds.

Flanks / Love Handles

3–5 sessions
Korean formulas reduce volume gradually but effectively.

Bra Bulge / Back Fat

2–4 sessions

Inner Thighs / Outer Thighs

3–5 sessions

3. Why Multiple Sessions Are Needed

Fat-dissolving injections break down fat gradually—your body then metabolizes the destroyed fat cells over several weeks. Because the solution can only target a safe amount of fat per session, treatment must be repeated for:

• consistent reduction
• smooth contour
• safe metabolism
• even melting without lumps

Korea focuses on gradual, natural slimming, not aggressive melting.

4. What Affects How Many Sessions You Need

✔ Amount of Fat in the Area

More volume = more sessions.

✔ Formula Strength

Korean formulas range from mild → medium → strong.
Stronger formulas may require fewer sessions but cause more swelling.

✔ Your Metabolism

Faster metabolism clears fat faster.

✔ Desired Results

Subtle change → fewer sessions
Sharp definition/V-line → more sessions

✔ Age & Skin Elasticity

Younger skin tightens better after reduction.

5. How Fast Do You See Results?

Most patients see:

• Small changes: 2–3 weeks
• Clear difference: After 2nd session
• Full results: 4–6 weeks after each session

Areas like the double chin respond very quickly.

6. How Long Do Results Last?

Fat-dissolving injections remove fat cells permanently.
As long as your weight stays stable, the treated fat does not return.

7. Should You Combine With Other Korean Treatments?

Many Korean clinics combine fat-dissolving with:

• HIFU / Ultherapy / Liftera → lift + tighten
• InMode / BodyFX → fat melting + contouring
• Jawline fillers → sharper definition
• RF tightening → prevents sagging

For double chin, the combo of fat dissolving + HIFU is extremely popular.

Final Answer: How Many Sessions Are Needed?

Most international patients need 2–4 sessions for visible, lasting fat reduction in Korea.

However, the number varies by area and fat volume:

• Small areas → 1–2
• Medium areas → 3–4
• Larger/stubborn areas → 4–6

Korean dermatologists always customize the treatment plan to maximize results while minimizing downtime.
