Short answer:
A non-surgical V-line combines three treatments that each fix a different part of the lower face: jaw botox slims a wide jaw by relaxing the masseter muscles, Shurink HIFU tightens loose skin under the jawline and chin, and jawline or chin filler sharpens the outline. In Gangnam, jaw botox costs about ₩50,000–₩250,000, Shurink about ₩150,000–₩500,000 and jawline filler about ₩500,000–₩1,200,000.
What makes a face look square or wide
- Large masseter muscles:
from chewing or clenching, they widen the lower face.
- Soft tissue and laxity:
fat under the chin and early jowls blur the jawline.
- Short or recessed chin:
without chin projection, the face looks rounder.
- Bone structure:
a wide jaw bone can only be changed with surgery.
The three non-surgical tools
Jaw botox
Jaw botox
is injected into the masseter muscles. The muscle gradually shrinks, slimming the lower face. The effect starts after 2–4 weeks, is clearest at about 6–8 weeks, and lasts roughly 4–6 months. There is no downtime, though chewing may feel weaker for about 2 weeks.
Shurink HIFU
Shurink Universe
is a Korean HIFU device that delivers focused ultrasound under the skin to tighten tissue. It helps with a soft jawline, mild jowls and a double chin. There is no downtime, and results typically last 3–6 months.
Jawline and chin filler
Jawline filler
adds definition along the jaw angle and chin for a sharper outline. Swelling lasts about 2–4 days, and results typically last 12–18 months.
The usual order
- Jaw botox first:
slims the width; wait 4–8 weeks to see the new shape.
- Shurink:
tightens the lower face, often on the same day as botox or later.
- Filler last:
fine-tunes the outline once the width and tightness have settled.
On a short trip, many visitors do botox and Shurink together and leave filler for the end of the stay or a later visit.

When surgery is the better option
If the width comes mainly from bone, injections cannot change it. In that case, a consultation with a board-certified plastic surgeon about V-line surgery
is the honest next step, keeping in mind its much longer recovery.
Risks to know
- Jaw botox:
temporary chewing fatigue, rarely an uneven smile if placed poorly.
- Shurink:
temporary tenderness or numbness; rarely nerve irritation.
- Filler:
swelling, bruising, lumps, and rare vascular complications, which is why an experienced injector matters.
Frequently asked questions
How long until jaw botox slims my face?
Changes begin after 2–4 weeks and are clearest at about 6–8 weeks.
Can I do all three on the same day?
Botox and Shurink are often combined; many doctors prefer to add filler later.
How often do I need to repeat them?
Jaw botox every 4–6 months, Shurink every 3–6 months, filler every 12–18 months.
Is non-surgical V-line permanent?
No. It is maintained with repeat sessions; only surgery changes the bone permanently.
