What Is the Girl-Group Injection in Korea?

The “Girl-Group Injection” (걸그룹 주사) is one of Korea’s most talked-about slim-face treatments. It’s a non-surgical injection designed to create the sharp, slim, V-line facial shape often seen on Korean idols and girl-group members.

This treatment combines fat-dissolving, contouring, and anti-swelling ingredients to make the lower face look slimmer, tighter, and more sculpted without surgery.

It’s extremely popular among Koreans and international visitors who want a fast, subtle, and Korean-style facial contour.

Why Is It Called the “Girl-Group” Injection?

The name comes from the iconic K-pop idol look:

  • Slim jawline
  • Snatched V-line
  • No jowl fullness
  • Defined chin contour
  • Smaller lower face on camera

The injection helps reduce puffiness, soften face fat, and improve overall contour—creating the signature “idol look.”

What’s Inside the Girl-Group Injection?

The exact formulas vary, but most include a mix of:

  • Mild fat-dissolving agents (PPC or low-dose DA)
  • Anti-swelling compounds
  • Lymphatic drainage boosters
  • Skin-tightening peptides
  • Anti-inflammatory ingredients

The formula is intentionally gentler than strong fat dissolvers like Kybella to avoid heavy swelling.
This makes it perfect for people who want a natural, low-downtime contouring effect.

What Areas Does It Target?

The Girl-Group Injection is used to slim and sculpt:

  • Jowls
  • Jawline / side chin
  • Lower cheeks
  • Double chin
  • Face puffiness
  • Overall V-line area

Some clinics also use a body version for arms or waist, but the original treatment is meant for the face.

Who Is the Girl-Group Injection Good For?

You’re an ideal candidate if you have:

  • Puffy or rounded lower face
  • Mild jowls
  • Baby-fat cheeks
  • Slight double chin
  • Uneven jawline contour
  • Mild facial asymmetry
  • Desire for a small and slim Korean-style V-line

It works best on mild to moderate fullness, not severe fat or major sagging.

How It Works

Here’s the typical process:

  1. Consultation & face analysis
  2. Mapping injection points for symmetry
  3. Light numbing (optional)
  4. Injection into specific fat pockets
  5. Cooling pack to reduce swelling

The appointment usually takes 5–10 minutes.

Results: What to Expect

Timeline

  • Day 1–2: Mild swelling or tightness
  • Week 1: Face feels less puffy
  • Week 2–3: Visible slimming of lower face
  • After 2–3 sessions: More defined jawline & V-line

Results look very natural—never “hollow” or overly sharp.

Downtime

Very minimal compared to stronger fat dissolvers:

  • Mild swelling: 1–3 days
  • Slight tenderness: 1–2 days
  • Makeup possible same or next day

Most travelers can continue their Korea itinerary with no problem.

How Many Sessions Are Needed?

Most people need:

  • 2–4 sessions
  • Spaced 1–2 weeks apart

Travelers often do 2 sessions during a 1–2 week trip.

How Long Do Results Last?

Results typically last 3–6 months, depending on:

  • Metabolism
  • Fat volume
  • Weight fluctuations

Some people repeat the treatment a few times per year to maintain the V-line.

Cost of Girl-Group Injection in Korea

The price varies by clinic, dosage, and formula.

Typical range:
₩50,000 – ₩150,000 per session

Still far cheaper than facial liposuction or strong fat-dissolving injections.

Girl-Group Injection vs Standard Fat Dissolving

Girl-Group Injection

  • Gentle
  • Minimal swelling
  • K-pop-style results
  • Good for puffiness + mild fat
  • Travel-friendly

Strong Lipolysis (PPC/DA)

  • More aggressive
  • More swelling
  • Better for thicker fat
  • Longer-lasting fat breakdown

Many patients combine both for better results.

Girl-Group Injection vs Jaw Botox

They treat different things:

  • Girl-Group Injection → fat & puffiness
  • Jaw Botox → muscle slimming

Many Koreans combine both for a full V-line makeover.



Korea’s Girl-Group Injection is a popular, gentle, and travel-friendly way to slim the face, reduce puffiness, and achieve a natural K-beauty V-line. It’s ideal for people who want subtle contouring without downtime or dramatic swelling.
