If you have searched jawtox and come away with prices that range from a few hundred pesos to tens of thousands, nothing is wrong with your search. Those numbers are measuring different things. This guide explains what jawtox does, what you are actually buying when a clinic quotes you, and when the result shows up.
Jawtox is masseter botox. The masseter is your chewing muscle, and you can find it by clenching your teeth and feeling the block that pushes out at the back of your jaw. Botulinum toxin injected into it blocks the signal telling it to contract, so it works less, and a muscle that works less loses bulk over the following weeks. The same principle as a muscle shrinking inside a cast, applied deliberately to one muscle.
At One Nadela, jawtox is primarily done to relieve symptoms associated with bruxism. It helps relax the masseter muscle to reduce teeth grinding and alleviate jaw tension as well as migraines. The slimmer lower face comes from the same injection, which is why one treatment does two jobs.
This is the question worth settling before you compare clinics or prices, because jawtox works on muscle and cannot change bone.
A wide or square jaw can come from a thick chewing muscle, from the jawbone itself, or from both. Years of clenching build the masseter the same way years of training build any other muscle, and a muscle built that way can be relaxed back down. Bone cannot. Where the width is structural, jawtox softens the look without altering the frame underneath it.
Telling those apart is what the consultation is for. At One Nadela, physical assessment is done through observation as well as careful palpation, to determine whether you are a good candidate for masseter botox before anything is injected.
This is where almost all the price confusion comes from, so it is worth understanding properly.
Botulinum toxin is measured in units, not in millilitres or syringes. A unit is a dose, and different muscles need different numbers of them. The muscles around the eyes are small and need few. The masseter is one of the strongest muscles in the body for its size, and it needs many.
At One Nadela a jawtox treatment typically takes 50 to 60 units across both sides, with the exact number set by the doctor after assessing how much muscle is actually there. Units are priced at ₱450 each, so a full treatment starts at around ₱22,500.
That is why a low advertised figure can mislead. ₱450 is one unit. ₱22,500 is the treatment. Both numbers can be honest and they are not comparable. When you ring around, ask every clinic the same question: what does the full treatment cost, and how many units is that.
Two things move the figure. A stronger masseter needs more units, which is why two people can leave the same clinic having paid different amounts. And the brand of toxin changes the per-unit price, with Korean brands generally sitting below United States ones. Either is legitimate when a licensed doctor is injecting.
It is an outpatient appointment and you walk out the same day.
The doctor assesses your jaw, asks you to clench, and marks the injection points on each side. The marking matters more than it looks, because the masseter sits close to the muscles that control your smile, so the safe zone is mapped rather than estimated.
Numbing cream is applied first for 15 to 30 minutes. The procedure itself lasts about 40 minutes to an hour, most of which is assessment and marking rather than injecting. Most patients describe a brief sting rather than pain, and there is no sedation and nothing to recover from afterwards.
Nothing changes on the day, which surprises people who expect a filler-style result. This is how it typically unfolds at One Nadela.
The effect typically lasts about 4 to 6 months, depending on muscle strength and patient metabolism, after which the treatment is repeated. How much slimming appears varies from person to person, mostly with how much of your jaw width was muscle to begin with.
Botulinum toxin has been used medically for decades, and the masseter is a well mapped injection site.
Common side effects include temporary redness, bruising and swelling. There might also be temporary weakness upon chewing and a possible uneven smile, but these resolve over time.
The uneven smile is the one worth understanding, because it is the reason injector skill matters. The muscles that lift the corner of your mouth sit near the masseter, so placement is what keeps the toxin where it is meant to be. That is the honest argument for a doctor who does this regularly rather than the cheapest appointment available.
If your jaw feels firm and muscular when you clench, and especially if you grind your teeth or wake with jaw tension, jawtox is worth a proper assessment.
Book a consultation at Cebu, BGC, or Makati. The doctor assesses your jaw, tells you honestly whether the width is muscle, bone, or both, and gives you an exact unit count and figure before anything is decided. Full pricing is on the jawtox treatment page, and if excessive sweating is also a concern, see sweatox.

Jawtox is masseter botox. A doctor injects botulinum toxin into the chewing muscle on each side of the jaw so it contracts less, and over several weeks the muscle reduces in bulk. It eases teeth grinding and jaw tension and slims the lower face from the same injection.
At One Nadela it is primarily used to relieve symptoms associated with bruxism, reducing teeth grinding and alleviating jaw tension as well as migraines. The lower face also looks slimmer as the muscle reduces, which is typically appreciated at about four weeks.
At One Nadela, typically 50 to 60 units across both sides. The doctor sets the exact number after assessing how much muscle is there, because a stronger masseter needs more.
The effect typically lasts about 4 to 6 months, depending on muscle strength and patient metabolism.
Numbing cream is applied for 15 to 30 minutes, then the doctor assesses your jaw, marks the injection points and places a series of small injections on each side. The procedure lasts about 40 minutes to an hour. No sedation, and most patients go straight back to their day.
Botulinum toxin has been used medically for decades and the masseter is a well mapped injection site. Common side effects include temporary redness, bruising and swelling, and there might also be temporary weakness upon chewing and a possible uneven smile, but these resolve over time.
At about four weeks, not week one. The muscle starts relaxing from around one week, the toxin takes full effect at two to three weeks, and the slimming is appreciated at about four weeks.
Units are ₱450 each and a treatment typically takes 50 to 60 of them, so it starts at around ₱22,500. Your exact figure is confirmed at consultation. Full details are on the jawtox treatment page.
