How Much Does Underarm Botox Cost? A Cosmetic Surgeon Explains Average Prices, Unit Counts, and Insurance Coverage Requirements

My journey into aesthetic medicine stems from a desire to help enrich and beautify lives beyond simply treating illness. My specialties include hyaluronic acid, Botox, and thread lifts. I provide treatments that enhance each individual's unique qualities and bring out an elegant, natural beauty. For concerns around the eyes that are difficult to improve with dermatology alone, I also perform surgical procedures. By integrating dermatology and surgery, I holistically balance the entire face. With three periods of overseas study, I am also able to provide consultations in English.

“How much does underarm Botox cost?” “What’s the difference between affordable and expensive clinics?” “If I have excessive underarm sweating, is the treatment covered by insurance?” Concerns about underarm sweating can affect daily life not only during the summer but throughout the year.

 

For example, some people may find that they can’t choose their favorite clothes because they’re self-conscious about sweat stains, or they may feel reluctant to raise their arms in public. “Underarm Botox” is one option for addressing these concerns related to underarm sweating.

 

Underarm Botox is a treatment in which a botulinum toxin solution is injected into the skin of the underarms to temporarily block nerve signals to the sweat glands, thereby reducing sweat production. When considering underarm Botox treatment, I place great importance on determining “how much you want to reduce sweating” and “the extent of the sweating.” The amount and area of underarm sweating vary from person to person, so the appropriate dosage and injection area will differ accordingly.

 

In addition, the price of underarm Botox varies depending on the product used, the number of units, and the procedure fee. Therefore, when comparing prices, it is important not to base your decision solely on a listing that says “Underarm Botox: X yen,” but to confirm the specific type of medication used, the number of units, and the total cost.

 

Furthermore, if you are diagnosed with severe primary axillary hyperhidrosis and meet certain criteria, you may be eligible to receive botulinum toxin treatment covered by insurance. In this article, focusing on the topic of “underarm Botox prices,” I will provide a detailed explanation from a cosmetic surgeon’s perspective, covering how to understand typical price ranges, cost differences based on the number of units, conditions for insurance coverage, the duration of effectiveness, and comparisons with other underarm sweating treatments.

 

Factors That Determine the Price of Underarm Botox in Ginza, Tokyo

Since this is a self-pay service, the pricing for underarm Botox varies among clinics in Tokyo and Ginza. That said, the following three factors are common across many cosmetic surgery, cosmetic dermatology, and cosmetic internal medicine clinics:

Preparations to Be Used

Prices vary depending on whether the product is approved domestically or imported, as well as on factors such as dilution and storage procedures. Be sure to check safety information and the clinic’s track record in advance at cosmetic surgery, cosmetic dermatology, and cosmetic internal medicine clinics in Ginza, Tokyo.

 

Please note that perceptions of the "Before & After" effects vary from person to person, and even with the same product, the experience may differ depending on the degree of sweating and individual constitution.

Number of units to inject

The number of units required varies depending on the extent and amount of underarm sweating. The definition of a unit differs for each formulation, so a direct conversion between different formulations is not possible.

 

Be sure to discuss during your consultation with a cosmetic surgeon, cosmetic dermatologist, or cosmetic physician that a higher number of units does not necessarily result in proportionally greater results.

Procedure Fees, Anesthesia Fees, etc.

In addition to the cost of the medication, you’ll be charged a physician’s fee and, if necessary, an anesthesia fee. To ensure you’re satisfied with your Botox treatment, be sure to confirm the total cost for both sides—not just the listed “medication-only” price—at each of our clinics in Ginza, Tokyo.

Estimated Costs and Cost Estimates (Example of Private Medical Care)

While there is no nationwide standard price for private medical care, as a general guideline, prices are often set at “500–900 yen per unit plus a treatment fee (e.g., 25,500 yen).” The typical amount injected into the underarms is often considered to be 40–120 units, and an example of the total cost is as follows.

・40 units: Approximately 45,500–61,500 yen (estimated total, including treatment fees)
・80 credits: Approximately 65,500–97,500 yen
・100 units: Approximately 75,500 to 115,500 yen
・120 credits: Approximately 85,500 to 133,500 yen

 

Please note that this is merely an example calculation; the actual cost may vary depending on the number of units and whether anesthesia is used. When obtaining a quote from a cosmetic surgery, cosmetic dermatology, or cosmetic medicine clinic in Tokyo or Ginza, be sure to ask for a total cost that includes the cost of medications, the number of units, and the procedure fee.

 

Please note that we make a distinction between medications used in private medical practice and domestically approved medications used under insurance coverage for severe primary axillary hyperhidrosis.

Understanding Credit Hours (The Difference Between 40, 80, and 100 Credits)

The units used for underarm Botox serve as a general guideline within the same formulation. While 40 units are generally considered a “small amount,” 80 units a “moderate amount,” and 100 units a “generous amount,” the appropriate dosage varies depending on “the amount and area of sweating,” “the response to the previous treatment,” and “lifestyle factors (such as the season and occupation).”

 

For domestically approved formulations, the recommended dose for adults with severe primary axillary hyperhidrosis is 50 units per side (100 units for both sides); however, this cannot be directly applied to other formulations. In clinical practice in Tokyo and Ginza, it is safer and more practical to determine the dose based on individual consultations rather than relying on a one-size-fits-all figure.

What are the eligibility requirements for insurance coverage? (Severe primary axillary hyperhidrosis)

Botox injections for the underarms may be covered by insurance if a patient is diagnosed with severe primary axillary hyperhidrosis and meets certain criteria. A score of 3 to 4 on the Hyperhidrosis Disease Severity Scale (HDSS), which is used to assess severity, is generally considered a guideline; however, coverage is not automatically determined based on the HDSS score alone.

 

Medical institutions in Tokyo and Ginza that provide insurance-covered care will make a determination based on the progression of your symptoms and whether you have any other medical conditions. The out-of-pocket cost varies depending on your age and income, so we cannot provide a fixed amount; however, it may be more affordable than private medical care.

Perceived Effectiveness, Duration of Effect, and How to Estimate Annual Costs

Patients typically begin to notice a reduction in sweating after a few days, and the treatment is usually evaluated after 1 to 2 weeks. The effects generally last for about 4 to 6 months, though this may vary depending on the specific formulation used, the number of units administered, and the patient’s individual constitution.

 

If you’d like to receive regular treatments to maintain results—assuming twice a year—you can estimate the annual cost as “total cost per session × 2” and schedule your appointments to coincide with life events (such as summer, presentations, or weddings).

 

Since excessive repetition over a short period may affect antibody formation and increase the risk of side effects, be sure to consult with a cosmetic surgery, cosmetic dermatology, or cosmetic internal medicine clinic in Ginza, Tokyo, regarding the appropriate interval between treatments.

Pain, Downtime, and Side Effects

You may experience a slight stinging sensation, redness, swelling, or bruising at the injection site. These symptoms are usually temporary, but their severity and recovery time vary from person to person. It has been noted that, in rare cases, side effects affecting the surrounding area may lead to muscle weakness; therefore, if you suddenly experience symptoms related to swallowing or breathing, you should seek medical attention immediately.

 

Be sure to check in advance with cosmetic surgery, cosmetic dermatology, and cosmetic medicine clinics in Tokyo and Ginza regarding whether cooling or anesthesia is available, as well as any precautions to take after returning home.

The Difference Between Underarm Sweat and Body Odor (Bromhidrosis), and the Role of Botox

Eccrine sweat glands are considered the primary cause of underarm sweating, while apocrine sweat glands are considered the primary cause of underarm odor. Botox reduces sweating by temporarily blocking nerve signals, but it is not a treatment that removes the sweat glands themselves.

 

While reducing sweat can alleviate moisture buildup and make body odor less noticeable, if your goal is to fundamentally treat underarm odor, you should consult a cosmetic surgery or cosmetic dermatology clinic in Tokyo or Ginza to discuss your options, including surgical treatments and energy-based devices.

Comparison of MiraDry and Surgery (Who Is It Best Suited For?)

・Underarm Botox: It’s easy to undergo via injection, and the downtime is relatively minimal. However, the effects are temporary, so repeat treatments may be necessary.
・Microwave therapy (e.g., MiraDry): This method works by applying heat to the sweat glands. While it aims to achieve long-term reduction, it may cause swelling or numbness.
・Surgical procedures (such as the inversion excision method): These primarily target the sweat glands responsible for underarm odor. Scarring and downtime must be taken into consideration.

 

Rather than comparing which is better or worse, you should choose based on “duration,” “tolerance for downtime,” “cost structure,” and “primary concern (sweating or odor).” It’s practical to have cosmetic surgery and dermatology clinics in Tokyo or Ginza present you with several options and then choose the one that best fits your lifestyle.

A Checklist to Help You Avoid Choosing Based Solely on Price

1) Medications Used: Confirm whether they are approved or unapproved in Japan and whether information has been disclosed.
2) Number of units: Clearly specify unilateral/bilateral, dilution, and total units.
3) Total Cost: Compare the total cost, including procedure fees, anesthesia fees, follow-up visit fees, and necessary supplies.
4) Assessment of suitability: Whether an evaluation of the underlying causes of hyperhidrosis (medications, endocrine factors, constitutional factors) has been conducted.
5) Planning: Design based on the next scheduled event and seasonal events.

 

While this applies not only to Tokyo and Ginza but to urban areas in general, the abundance of options in these areas means there’s a lot of information to process, which can make it easy to feel overwhelmed. Whether you’re looking for cosmetic surgery, cosmetic dermatology, or cosmetic internal medicine, it’s reassuring to choose a clinic that carefully explains the basis for their estimates.

Looking at the Cost of Underarm Botox from the Same Perspective as Comparing Prices for Liposuction and Breast Augmentation

In the field of cosmetic surgery, the total cost of procedures such as liposuction and breast augmentation varies depending on the “surgical technique, treatment area, anesthesia, and post-operative care.” The same principle applies to underarm Botox; the cost is determined by the “product, number of units, procedure fee, and number of visits.”

 

At cosmetic surgery, cosmetic dermatology, and cosmetic internal medicine clinics in Tokyo and Ginza, we conduct consultations for underarm sweating treatments by applying the same approach used for procedures like liposuction—determining the treatment area—and breast augmentation—understanding the patient’s desired outcome.

 

For example, just as you would discuss in detail “which areas to treat and to what extent” during liposuction, it’s helpful to clearly define “in which situations you want to reduce sweating (commuting, business meetings, formal events, sports)” when considering underarm Botox. Similarly, just as you would discuss the “balance between size and a natural look” for breast augmentation, you’ll discuss the “balance between the degree of sweat reduction, duration of results, and the need for follow-up treatments.”

 

If you keep in mind the similarities between this procedure and liposuction or breast augmentation, it will be easier to understand the basis for the estimate, leading to a more informed investment decision. It’s also worth noting that even at cosmetic surgery clinics in Ginza, Tokyo—which specialize in liposuction and breast augmentation—underarm Botox treatments are increasingly being performed in collaboration with cosmetic dermatology and cosmetic internal medicine practices.

 

When different areas of expertise come together, safety checks and the development of annual plans tend to be carried out more thoroughly.

Tips for Choosing a Clinic in Ginza, Tokyo (Cosmetic Surgery / Cosmetic Dermatology / Cosmetic Internal Medicine)

・Cosmetic Surgery: Proposals often take a patient’s lifestyle into account, including surgical options such as liposuction and breast augmentation. Underarm Botox treatments can also be easily planned based on “specific concerns in different situations.”
・Cosmetic Dermatology: Specializes in evaluating skin and sweating. It’s easy to design a step-by-step treatment plan that incorporates complementary skincare products and device-based therapies.
・Cosmetic Internal Medicine: Evaluates overall bodily balance from the perspectives of constitution, hormones, and the effects of medications. You can receive advice that takes into account the relationship between excessive sweating and your physical condition.

 

There are many options in Tokyo and Ginza, and clinics in every specialty will assess which treatments are right for you. Having a system that integrates multiple perspectives makes it easier to receive treatment recommendations that go beyond just Botox injections—such as liposuction or breast augmentation, if necessary—which is more likely to lead to long-term satisfaction.
