Jaw Botox vs Jawline Thread Lift — Cheongdam & Apgujeong, Seoul

Width from muscle, or blur from sagging?

People often describe the same complaint — “my jaw looks heavy” — for two quite different reasons.

Muscle width. The masseter is the chewing muscle at the angle of the jaw. When it is large, often from clenching or grinding, the lower face looks square from the front. Jaw Botox (사각턱 보톡스) relaxes the muscle so it gradually reduces in bulk, slimming the face over several weeks.

Sagging. With age, soft tissue and the SMAS layer descend; jowls form and the line from chin to ear blurs. Here, the jaw is not too wide — it is simply less defined. A jawline thread lift uses dissolvable threads placed under the skin to lift and reposition that tissue. Doje has 17 years of accumulated thread-lift experience and designs each lift to face shape and degree of sagging.

Using the wrong one wastes time: Botox will not lift jowls, and threads will not shrink a large muscle.

How Doje Clinic decides

Dr. Byun Jeik, a surgery specialist and Merz Ultherapy and Belotero award recipient, examines the face at rest and while clenching. If the muscle bulges strongly when you bite, masseter size is part of the story. He then assesses jowls, the depth of marionette lines and skin elasticity.

• Square jaw, firm tissue, often in your 20s–30s — Jaw Botox is usually the starting point.
• Jowls and a blurred jawline, often later in life — a lower-face thread lift through the Jawline Program.
• Both a strong muscle and early sagging — a sequenced combination.
• Fullness under the chin — double-chin liposuction or ONDA may be relevant too.

Jaw Botox vs jawline thread lift side by side

When Doje combines them

A common pattern in the 30s and 40s is a strong masseter plus the first signs of jowling. Slimming the muscle with Botox narrows the frame, and a thread lift then sharpens the line. Doje usually sequences these thoughtfully so each effect can be judged, and adds Radiesse, Ultherapy Prime or ONDA only where structure, deeper tightening or fat reduction is needed.

Which should you choose?

• Jaw Botox if your face looks wide at the angle of the jaw and the muscle bulges when you clench.
• Jawline thread lift if the problem is jowls or a softened jawline rather than width.
• Both if you have a strong muscle and early sagging.
• Something else if bone structure or fat under the chin is the main factor.

Cost

Both are quoted after a 1:1 consultation; the number of threads or units depends on your face. Korean non-covered (비급여) aesthetic fees are set per plan; ask for a written quote.

Frequently asked questions

Can Jaw Botox lift jowls?

No. It slims the masseter muscle but does not lift sagging tissue. Jowls are usually addressed with a lower-face thread lift or lifting device.

How long does a jawline thread lift last?

Doje states results can last up to two years or more, but individual results vary with age, skin and lifestyle.

Will Jaw Botox affect chewing?

Some people notice their chewing feels weaker for a while, which usually adapts. Dosing is planned to keep function comfortable.

Are threads visible or lumpy?

Doje uses meticulous technique to avoid lumpiness, though temporary irregularities can occur while swelling settles.

Can both be done on the same trip?

Often, if your schedule allows. Dr. Byun will suggest the order and timing in your consultation.

Is a thread lift painful?

It is performed under local anaesthesia. Tightness and tenderness for some days afterwards are common.
