What are V line injections?
"V line" describes the slim, tapered jaw and chin that is popular in Korea. V line injections are a group of non-surgical treatments used to achieve it. The most common is jaw Botox: botulinum toxin is injected into enlarged masseter (chewing) muscles, which relax and gradually become smaller, softening a square jaw over several weeks.
Where the width comes from soft fullness rather than muscle, the doctor may suggest fat-dissolving contour injections (listed as Egg Line Injection on our price list), given in a short series to reduce small fat pockets along the jaw and under the chin. Some people also benefit from a little chin filler to lengthen the profile. The doctor combines these based on your anatomy.

Who is a good candidate?
- A square or wide jaw from strong masseter muscles
- Teeth clenching or grinding that has enlarged the jaw muscles
- Mild fullness along the jawline or under the chin
- Anyone wanting a slimmer face without surgery or downtime
Injections cannot change the shape of the jaw bone, so a wide bony jaw will see limited change, and very loose or sagging skin usually responds better to lifting such as a V-line thread lift. Treatment should wait during pregnancy or breastfeeding, with a skin infection in the area, or with certain neuromuscular conditions. The doctor will check this at consultation.

How the treatment works
-
Consultation
The doctor feels the jaw muscles as you clench and assesses fat, skin and bone to decide which injections suit you.
-
Preparation
The skin is cleansed and injection points are marked. Numbing cream or ice can be used if you prefer.
-
Injection
Botox is placed into the masseter muscles and, if planned, contour injections into areas of fullness. It takes about 10–20 minutes.
-
Aftercare
Avoid massaging the jaw, saunas and intense exercise for 24 hours. Mild swelling from contour injections usually settles in a few days.
Tips for international patients
- Send front and side photos on WhatsApp so the doctor can give an initial view before you travel.
- Jaw Botox takes a few weeks to show, so have it done early in your trip or plan to see the full effect at home.
- Contour injections usually need several sessions a week or more apart, so tell us how long you are staying.
- Avoid chewing gum and very tough foods for the first few days after jaw Botox.
Frequently asked questions
How long do V line injection results last?
Jaw Botox results typically last around four to six months, and repeated treatments may help the effect last longer. Fat reduced by contour injections tends to stay away if your weight stays stable.
When will I see results from jaw Botox?
The jaw starts to look slimmer after about two weeks, with the full effect usually visible at four to six weeks.
Do V line injections hurt?
They use a fine needle, so most people feel only brief pricks. Contour injections can sting or feel warm for a short time.
Will jaw Botox affect my chewing or smile?
When placed correctly into the masseter, it should not affect your smile. Some people notice slight chewing fatigue with tough foods for a few weeks.
Can V line injections replace jaw surgery?
No. Injections reduce muscle bulk and soft fullness but cannot reshape bone. The doctor will tell you honestly what injections can achieve.
How much do V line injections cost in Seoul?
The price depends on which injections and how many sessions you need, so the doctor confirms it at consultation. See the Egg Line Injection price list and our jaw Botox prices.
