Botulinum toxin placed in the chewing muscle to soften a square lower-face outline — but only when the width is muscle, and only after a diagnosis says so.
A wide lower face comes from muscle bulk, from the bone underneath, from fat, or from a combination of the three. Only the first answers to a toxin injection. So the assessment carries more weight than the injection does: palpating the angle while you clench, reading the outline in three dimensions, and being willing to say that the width in front of us is not the kind this treatment changes.
The same complaint — "my jaw looks too wide" — arrives with four different causes. Only one of them is treated here.
The angle of the jaw hardens noticeably under your fingers when you bite down. This is the pattern masseter toxin is designed for, and the one where a change in outline is realistic.
Grinding at night or clenching through a stressful season builds the muscle the way training builds any other. Toxin softens the bulk; it does not stop the grinding, so the habit is worth addressing alongside the treatment.
Sometimes the lower face reads heavy because the chin is short while the jaw itself is a normal width. That is a projection question, and we do not recommend masseter toxin for it.
If the width sits in the bone, no injection will move it. We say so at the diagnosis, and we will not book a session that cannot deliver what you came in hoping for.
The injection itself takes about a minute. Deciding the map, the tier and the dose is what the appointment is for.
Your director marks the working area of the masseter while you clench, staying inside the safe envelope and away from the muscles that shape your smile. The map is drawn on your own anatomy at the chair, and it is redrawn at each visit.
Dear stocks both Korean and premium imported botulinum toxin for this treatment, and both prices are published below. You choose with the difference explained, before the vial is drawn.
Amount is set by how strong and how thick your masseter actually is, and by how much softening suits the rest of your outline. We would rather review and add than overshoot a jawline that cannot be put back this month.
Lower-face contouring here runs from toxin through fillers to the lifting devices. When the outline turns out to be a chin problem or a laxity problem, saying so changes which room you are booked into and nothing else.
EVE Muse 3D imaging under five light sources shows the jaw from angles a mirror never gives you, and it separates muscle bulk from the shape of the bone beneath. Your director reads that alongside palpating the angle while you clench. Both have to agree before a product is chosen.
Depth and position within the muscle change how the jawline settles and how chewing feels for the first weeks; placed too superficially the skin over the angle can dimple, and placed unevenly the two sides soften at different rates and need evening up at review. Bruising at an injection point is the common minor risk. Every injection is performed by our directors, who dose conservatively at the first session and top up at the review if the outline has not moved enough.

Korean pharmaceutical advertising rules do not allow prescription toxin products to be named in public marketing, so the table lists tiers instead of brand names. That restriction covers this page and stops at the consultation-room door: your director tells you exactly which product is being used, and shows you the vial, before it is drawn. The full published price list covers every other area we treat. A cheaper headline figure for jaw botox in Korea usually describes a different tier, a partial dose, or a total that grows once you are in the chair; the two figures above are what you pay here.
If the width in front of us is bone, no injection moves it. If what you actually dislike is a short chin, we will say no to the masseter and send you to a chin consultation instead. Either way you hear it at the diagnosis, before a product is opened.

I've visited clinic for LDM procedure. I don't speak Korean, so there was an interpreter who assisted me while consulting. The staff was very attentive, they asked me every time before applying products/covering my face during the procedure and it went smoothly. Planning to visit the clini…
All the staff are kind, the doctor is professional. They recommended us the treatment that fit us best and last the longest. A very nice experience overall.
