BOTULINUM TOXIN

Botulinum Toxin

Botulinum toxin relaxes the muscles that create expression lines. It is also used to slim a square jawline, soften a gummy smile and reduce underarm sweating. Results appear gradually over about two weeks and last three to four months.

PackagesALL-INCLUSIVE

Each package covers the consultation with the doctor, the treatment named in that package, topical anaesthetic where it is used, and aftercare guidance. Nothing is added to the price of the package itself. If you decide during the consultation to add a further treatment, an additional area, or a stronger anaesthetic, that is charged separately — the doctor will tell you the amount before anything is carried out.

ABOUT PRICING

Prices are shown in US dollars. Payment is taken in Japanese yen at the equivalent amount shown, by cash or credit card. The conversion is fixed at ¥160 to the dollar and is reviewed quarterly, so it will not track the daily exchange rate.

About additional charges. The package price covers the treatment you select. Adding another treatment, another area, or an option such as nitrous oxide sedation or a blunt cannula is charged on top. The doctor explains the cost before proceeding, and you are free to decline.

LANGUAGE

How we communicate. Consultations are usually conducted with the help of a translation app, which our staff use routinely and which works well for the questions that come up in a consultation. Some of our doctors and staff can also handle straightforward English. Please write down anything you particularly want to ask before your visit — it makes the consultation smoother, and you are welcome to send questions on LINE in advance.

    Takes about 10 minutes. A topical anaesthetic cream (¥3,300) is available on request.

Risks and side effects

Temporary bruising, swelling, headache, or a heavy feeling in the eyelids or brows can occur. Rarely the effect may be uneven between the two sides, which can usually be adjusted at a follow-up visit. Effects are temporary and wear off over three to four months.

Who cannot be treated

Not suitable during pregnancy or breastfeeding, or for people with neuromuscular disorders. Please tell the doctor about any medication you are taking.

Please note

Results vary between individuals and no particular outcome can be guaranteed. This is elective private treatment and is not covered by Japanese national health insurance.

The device, product or needle used is selected by the doctor based on your skin condition, your goals and your condition on the day. For detailed questions, asking the doctor directly at your consultation is the most reliable way. You may also ask on LINE, but technical questions need to be checked with our clinical staff first, so a reply may take some time.

Questions

How soon will I see a result?
The effect starts around day three and is complete at about two weeks. If you are visiting Japan briefly, the change will appear after you return home.
Will my face look frozen?
Not if the dose is right. We start conservatively and can add more at a follow-up if you want a stronger effect.
Does it hurt?
The needle is very fine and each injection takes a second. Numbing cream is available if you prefer.
How long does jaw slimming take?
Muscle reduction is gradual — most people notice the change at four to six weeks and it lasts around six months.
Can I fly the same day?
Yes. There are no restrictions on flying after treatment.
Do you speak English?
Yes. Consultations can be conducted in English. Please let us know when booking.
