Face Lift and Jaw Slimming in One Visit, Planned by Doctors in Bangkok
This program has two parts in one visit. First, HIFU (focused ultrasound) firms the skin along the jawline and under the chin. Then a doctor injects botulinum toxin into the masseter, the chewing muscle that can make the lower face look wide. The visit takes 60 to 90 minutes. The price is 9,999 baht per treatment plan, which covers HIFU for the lower face and under the chin, jaw slimming injections and 1 free laser session. You pay the same price as Thai customers. The jaw usually starts to look slimmer at 3 to 4 weeks.

Why Addressing Two Layers Matters
A wider or softer lower face often comes from both the chewing muscle and loose skin.
Why One Treatment Alone Often Falls Short
If you only shrink the jaw muscle while skin is loose, the skin can sag once the muscle gets smaller. On the other hand, if you only firm the skin, your lower face stays wide because the muscle is still large.
By pairing HIFU with jaw slimming injections in one visit, we firm the skin and relax the muscle together. This helps give you a balanced, natural look.
Understanding the 4 Facial Layers
Your lower face is shaped by four layers. Layer 1 is the skin, where collagen and elastin keep it firm. Layer 2 is the fat under the skin. Layer 3 is the SMAS, a supporting layer that holds the face in place. Layer 4 is the masseter, the primary chewing muscle that expands from habits such as chewing tough foods, chewing on one side, or grinding teeth during sleep.
How HIFU and Jaw Slimming Injections Work Together
The order of the two steps matters, so we always do them the same way.
Why We Do HIFU First
We always do HIFU first and jaw injections second. HIFU sends gentle heat into the deeper layers of skin along the jawline and under the chin. This helps your skin make new collagen and tighten up.
Next, the doctor injects botulinum toxin into the chewing muscle. We always do HIFU first, because the heat from ultrasound could weaken the botulinum toxin if injections were done before it.
How the Injection Works
Many people know jaw slimming injections as jaw Botox. We use the general medical name, botulinum toxin, because what matters is the doctor's plan for your face.
Botulinum toxin lowers the nerve signal that tells the jaw muscle to tighten. The busy muscle rests and slowly becomes smaller over several weeks.
Medical literature describes jaw muscle injections as an off-label use of botulinum toxin, which means this use is not one of the uses listed on the product label. Your doctor will explain this before treatment.
4 Ways to Check the Product Is Genuine
You can check the product yourself before anything is injected.
Point 1 - Hologram Sticker
Look at the hologram sticker from the official distributor in Thailand.
Point 2 - QR Code Verification
Scan the verification QR code on the packaging using your smartphone to confirm the unique serial number and manufacturing lot.
Point 3 - Opened in Front of You
Our doctor unseals the new box, mixes the solution, and draws the medicine in front of you before treatment.
Point 4 - Take Box and Bottle Home
You can take the original box and empty medicine bottle home with you.
Product Origin and Medical Advice
We use genuine botulinum toxin type A made in South Korea and registered with the Thai FDA. The doctor will check if your wide lower face comes from a large jaw muscle, or if loose skin needs a different treatment. If injections will not help you, the doctor will tell you straight away and will not suggest treatment you do not need.
What to Expect During Your Visit
Your visit takes 60 to 90 minutes in one appointment.
| Step | Procedure | Time | Description |
|---|---|---|---|
| 1 | Face structure assessment | 15 to 20 minutes | The doctor examines your jawline and chewing muscle to confirm suitability. |
| 2 | Check the product with the doctor | 5 minutes | Check the hologram sticker, scan the QR code, and watch the doctor open the sealed product. |
| 3 | Skin prep and cooling | 10 to 15 minutes | Gentle skin cleansing and comfortable cold compress application to prepare the skin. |
| 4 | Focused ultrasound lift | 20 to 30 minutes | Focused ultrasound delivers targeted warmth to the deep skin and SMAS layer. |
| 5 | Jaw injections with a fine needle | 10 to 15 minutes | Precise botulinum toxin injections into the masseter muscle using a fine needle. |
| 6 | Aftercare advice and follow-up booking | 5 minutes | Personal aftercare instructions, take-home box, and follow-up appointment planning. |
Recovery and Results Timeline
Here is what happens in the days and weeks after treatment.
Day 1 to 3 - Initial Firmness
Initial tightening sensation along the lower jaw. Any mild redness from ultrasound typically resolves within 1 to 2 hours.
Week 1 to 2 - Muscle Softening
Within 1 to 2 weeks, the jaw muscle begins to feel softer to the touch when clenching. Chewing very tough food may feel temporarily more tiring.
Week 3 to 4 - Visible Slimming
The lower face begins to look slimmer as the masseter muscle shrinks and the skin stays smooth.
Month 1 to 3 - Settled Results
The skin settles around the slimmer jawline. Our medical team estimates that the result lasts about 4 to 6 months, depending on your muscle and daily habits.
What Studies Say About Timing
The jaw muscle starts to relax within days, and the slimmer look usually shows from about 3 weeks.
Some people find chewing tough food more tiring for a while, and this usually settles on its own.
Medical reviews report that the effect on the jaw muscle lasts about 3 to 6 months.
In a systematic review, most people had tighter skin at 3 months, and the improvement continued for up to a year.
Post-Treatment Care and Recovery Guidance
Simple steps to help your skin and muscles heal well.
Medical Aftercare Advice
Most people go back to work and normal activities straight away.
Small bruises, redness, swelling or soreness where the needle went in are the most common side effects, and a bruise usually fades in about a week.
Do not rub or massage the treated area for 12 hours, stay upright for 3 to 4 hours, and avoid strenuous exercise for 24 hours.
Redness, sometimes with mild swelling, is common after focused ultrasound and passes on its own. Numbness or extra sensitivity is rare.
Travel Planning and Flying Considerations
What you need to know if you are visiting Bangkok from abroad.
Guidance on Flying and Appointments
The NHS flying advice of 7 to 10 days is written for facial surgery, not for injections or focused ultrasound.
We have not found guidance from major medical bodies about flying after these non-surgical treatments, so tell us your travel dates and our team will plan your follow-up with you.
The NHS advises anyone having cosmetic treatment abroad to ask where follow-up appointments will be.
If you need to leave Bangkok before your in-person follow-up appointment, we can do your follow-up check by LINE video call.
