How the jawline changes

A defined jawline depends on three things: the bone, the muscles over it and the soft tissue that hangs from it. A large masseter, the chewing muscle at the back of the jaw, makes the lower face look square, especially in people who clench or grind. With age, the jowl fat pads drop and the skin loosens, so the clean line from chin to ear softens. Small fat deposits under the chin and along the jaw add to the blur.

Common jawline concerns

Concerns here include a square jaw, jowls, a double chin and marionette lines. The Korean V-line look combines a slimmer lower face with a tapered chin, but your doctor aims for balance with your own features.

Combining treatments

Jaw Botox narrows the face from the side, while lifting devices sharpen the line from below, so the two are often paired. Fat-dissolving injections can be added where a small pocket remains. Devices go first on the day and injections last. The V-Line Contour Package combines Jaw Botox, Shurink Universe and fat-dissolving injections. Compare jaw Botox vs fat-dissolving injections and HIFU vs RF lifting to see how they differ.

Planning around your trip

Jaw Botox and most lifting devices need no recovery, so they suit even a short stay. Slimming from Botox appears after you fly home. Threads need a few quieter days for swelling to settle.

Jawline safety notes

Jaw Botox: chewing tough food may feel weaker for a few weeks. High doses or frequent repeats in slim, older faces can make the cheeks look hollow, so doses are tailored.
Nerves along the jaw: HIFU and injections are placed to avoid the small nerves near the jaw; brief tingling or numbness can occur and usually settles.
Threads: expect swelling or bruising for 3–7 days, and avoid wide mouth opening, dental work and facial massage for the first couple of weeks.
Who should wait: toxin and injectables are postponed during pregnancy and breastfeeding; RF and microwave devices are not used with a pacemaker.

Treatments are performed by licensed medical doctors. Browse all treatment areas, or book a consultation and your doctor will build a V-line plan around your bone structure.

How many units of jaw Botox do I need?

It depends on the size and strength of your masseter muscles. Korean clinics usually price jaw Botox for both sides, and your doctor sets the dose after feeling the muscle as you clench. See how many units of jaw Botox you need.

When will my jaw look slimmer?

The muscle starts to relax within a week or two, and visible slimming usually shows from about 2–4 weeks, with the fullest effect a little later. Results last about 4–6 months.

Will jaw Botox help with teeth clenching?

Many people find it eases clenching and jaw tension. It does not replace a dental assessment if you grind your teeth at night.

Should I choose HIFU or a thread lift for jowls?

HIFU suits mild laxity and has no downtime. A thread lift gives a more visible lift for heavier jowls but needs 3–7 days for swelling. Read thread lift vs Ulthera Prime.

Can I fly after jaw Botox?

Yes. Flying the next day is generally fine, and the slimming effect develops over the following weeks.
