How many days does Botox underarms take effect after? Complete guide to duration, number of units, and effects on odor.

Underarm sweat that oozes still not only on hot summer days, but also in tense or stressful situations. Have you long suffered from sweat stains on your precious clothes and an unpleasant odor that makes you feel uncomfortable in the eyes of others? In fact, Botox underarms, a cosmetic treatment, may be the answer to these problems that are difficult to solve with deodorant products.

But, "When will the effects start to show?" How many times do I have to go to the clinic? What is the right dosage (number of units) for me? Will the injections work on armpit odor as well? There are many questions and concerns that arise before undergoing a treatment. Here, we will explain in more detail than anywhere else and in a way that is easy to understand from a specialist's point of view the detailed process until the effects appear, how to choose the optimal number of units, the truth about the effects on odor, and how to choose a clinic so as not to regret it.

 

What is Botox Underarms? Mechanism of Effectiveness and Indications

You may have heard the term "Botox underarms," but you may not know exactly why it stops sweating or how it works. This treatment has the potential to do much more than simply reduce sweating; it has the potential to greatly improve your quality of life.

In this section, we will thoroughly explore the scientific mechanism by which Botox Underarms works, what symptoms it is suitable for, and what advantages it has over other treatments. We will take the time to determine through this whether you are eligible for treatment with Botox underarms. First, let's start by understanding the heart of this treatment, the mechanism that controls sweating.

How Botox reduces perspiration and its effect on sweat glands

Why does a single injection stop the underarm sweating that has been a problem for so many years? The key is the relationship between the "sweat glands" in our body and the "neurotransmitters" that convey commands from the brain. Botox underarms can have an amazing antiperspirant effect by precisely approaching this command system.

There are two types of sweat glands in our bodies. One is the eccrine sweat gland, which is responsible for the regulation of body temperature and produces dry sweat. The other is the "apocrine sweat gland, "** which produces sticky sweat that causes a distinctive odor. It is mainly the eccrine sweat gland that is largely responsible for the "volume" of underarm sweat.

When the brain feels "hot" or mentally tense, a command to "sweat" is sent through the nerves to the sweat glands. At this time, a neurotransmitter called acetylcholine is released from the nerve endings, which is received by the eccrine sweat glands, causing us to sweat.

The botulinum toxin preparation used in Botox underarms acts on these nerve endings and blocks the release of acetylcholine itself. Since the substance that carries the command is no longer produced, the sweat glands are no longer able to receive the brain's command to "sweat," resulting in a dramatic reduction in sweating.

On the other hand, its effect on apocrine sweat glands, which cause armpit odor, is considered limited. Since apocrine sweat glands are also dominated by acetylcholine, a secondary effect of reducing odor by slightly inhibiting sweating can be expected, but other treatments may be recommended if the goal is to treat the root cause of the odor.

Does this apply to you? Characteristics of people who are suitable for Botox underarms

You may be wondering, "Is my underarm perspiration at a level that requires treatment?" Many people may wonder, "Is my underarm sweating at a level that requires treatment? Botox underarm treatment is especially recommended for those with "primary axillary hyperhidrosis" who suffer from excessive sweating that interferes with daily life.

Primary axillary hyperhidrosis is determined by the following diagnostic criteria

• Unexplained excessive underarm sweating for more than 6 months
• The first symptom was under 25 years of age
• Sweating equally profuse on both right and left sides
• Sweating has stopped during sleep.
• At least one episode of hyperhidrosis per week
• Someone in the family has similar symptoms.
• Sweat interferes with daily life.

If the patient meets these diagnostic criteria and is judged to have particularly severe symptoms, treatment may be covered by insurance. Insurance coverage is available only when other treatments, such as topical medications (ointments), do not provide sufficient effect and the diagnosis is severe, with a severity score of 3 or higher as shown below.

If the score is 3 or higher, the quality of life is likely to be greatly improved by Botox underarms.

Comparison with other hyperhidrosis treatments: why you should choose Botox underarms

Underarm Botox is not the only treatment for hyperhidrosis. There are a variety of options ranging from topical medications to surgery, each with its own advantages and disadvantages. It is important to choose the most appropriate method, taking into consideration your lifestyle, the severity of your symptoms, the cost and time available for treatment, and other factors.

Here we compare the characteristics of the major hyperhidrosis treatments and clarify in which cases Botox underarms is most appropriate.

Based on this comparison, Botox underarms is recommended for the following patients

• Those who are not comfortable with surgery but want more reliable results than with topical or oral medications.
• Those who want to reduce perspiration for a limited period of time, such as only during the summer or only before a specific event such as a wedding.
• Those who are too busy with work or schoolwork to take downtime.
• Those who wish to be treated without scarring.

Botox underarms is a very well-balanced treatment that is both highly effective and less stressful on the body. The step of first experiencing the effects of this treatment method and then considering permanent treatment in the future is also a wise choice.

 

How long does Botox underarms last? A Thorough Explanation of Duration and Durability

Next to feeling that Botox underarms may be the right treatment for you, you may be wondering, "When will it start working and how long will the comfort last?" After deciding to undergo the treatment, you may have to wait for a specific number of days until the effect appears, or for a specific time period. In making the decision to undergo treatment, it is very important to know the exact number of days it will take for the effects to appear and how long they will last.

In this section, we will explain the detailed process of how the effects of Botox underarms are manifested, following the chronological progression of the procedure. In addition, we will thoroughly explain the factors that affect the duration of the effect and the secrets to maximize and maintain the effect for a long period of time.

How long does it take to become effective and how long does it take｜When does the sweating stop?

The effects of Botox underarms do not appear immediately after the procedure. It takes some time for the drug to act on the nerves and block sweat secretion. In most cases, the changes come gently over several days. It is important not to rush and to observe the changes in your own body.

(1) 2-3 days after treatment: initial signs of change

Many people start to feel the effects from this period. You may feel a slight change, such as, "My underarms feel drier than usual," or "I may be sweating a little less in tense situations." You may feel faint changes such as "My underarms feel drier than usual" or "I may sweat less in tense situations. Although the effect is not yet complete, you should take it as a positive sign that the drug is beginning to work.

(2) 1 week after treatment: Time to start feeling the effects

This is when many people notice a clear reduction in perspiration. Sweat spots that used to bother them are almost completely eliminated, and they can confidently wear gray T-shirts, silk blouses, and other colored clothing that they used to avoid. The comfort in daily life will be greatly improved, and the effects of the treatment will be strongly felt.

(iii) 2 weeks after treatment: maximum effect reached

Approximately two weeks after the procedure, the drug's effect reaches its peak and stabilizes. At this point, perspiration is barely noticeable and the maximum effect of Botox underarms can be experienced. Many people find that they use deodorant less frequently or do not need it at all. If you feel that the effects are not enough at this point, it is an appropriate time to consult a doctor.

Duration of effects and individual differences｜How long will the comfort last?

The effects of Botox underarms are not permanent, but a single treatment can provide long-term relief from sweating problems. Since its duration varies from person to person, it is important to understand your body's characteristics and to continue treatment systematically.

According to Japanese practice guidelines, the duration of effect of Botox underarms is reported to be 4 to 9 months. However, the average period that most people experience is generally 4 to 6 months. This is because new nerve branches regenerate over time from the nerve endings blocked by Botox and begin to transmit commands to the sweat glands again. When the effect wears off, you will feel a gradual increase in sweating over several weeks, rather than a sudden return to normal.

The duration of the effect will vary from person to person due to the following factors

• Physical constitution and metabolic rate: Those with high metabolism tend to break down the drug and regenerate nerves more quickly, which may shorten the duration of the drug.
• Number of units injected: Injecting the appropriate amount for the symptoms, or a slightly larger number of units, tends to increase the duration of the treatment. (The number of units is discussed in more detail in the next chapter.)
• Number of treatments: It has been reported that in some cases, after repeated treatments, the function of the sweat glands gradually atrophies and the duration of the effect is longer than the first time.

It is also wise to have the treatment coincide with the season when sweating is a particular concern. For example, if you have your treatment in early spring (April-May), you will be comfortable during the summer months (June-September) when you are most likely to sweat.

Key points to maximize effectiveness and longevity

Since you are undergoing this treatment, you want to maximize its effectiveness and maintain it for as long as possible. There are several important points to consider in order to get the full benefit of Botox underarms.

(1) Select the appropriate number of credits

The most important factor that determines the effectiveness and duration of the procedure is the "number of units" of Botox injected. Too few units may result in inadequate effect, while too many units may result in unnecessary costs. Choose a clinic where the doctor can accurately diagnose your symptoms and recommend the optimal number of units.

(2) Observe appropriate treatment intervals.

Do not wait too long between treatments because you want to get the next one as soon as possible. Repeated treatments in a short period of time can cause the body to develop "antibodies" against Botox, and there is a risk that the drug will become less effective in the future. Japanese practice guidelines also state that re-dosing should be done after the effect has worn off, with an interval of at least 4 months.

(iii) Thorough aftercare

The way you spend the day of your treatment will also affect its effectiveness. On the day of the procedure, avoid activities that excessively stimulate blood circulation, such as strenuous exercise, saunas, prolonged bathing, and excessive alcohol consumption. Too much blood flow may cause the injected drug to diffuse to non-target areas, which may diminish its effectiveness and increase the risk of unexpected side effects.

4) Review lifestyle habits

Although Botox can suppress sweating, excessive stress and poor diet can affect the autonomic nervous system and cause an imbalance in the body as a whole. Providing time for relaxation and eating a well-balanced diet are also beneficial in supporting the effects of treatment.

 

What is the difference between 50 and 80 units of Botox? How to choose the right number of units

In the previous chapter, we discussed the duration and duration of the effects of Botox underarms. What directly affects the strength and duration of the effect is the amount of Botox injected, or the "number of units. Many people are confused about the balance between the cost and effectiveness of Botox and wonder which is the right amount for them.

In this section, we will explain in detail and in an easy-to-understand manner the differences in effectiveness depending on the number of units, how to choose the optimal number of units for your symptoms, and the decision-making process to avoid regrets.

How does the number of credits affect the effectiveness of a 50-credit vs. 80-credit program?

The first thing to understand when considering Botox underarm treatment is the term "unit". This is an international measure of the amount of botulinum toxin, not its weight (mg), but its biological activity (potency). In other words, the higher the number of units, the more power it has to block more neurotransmission.

Generally, Botox underarms in self-funded treatments range from 50 to 100 units. So what exactly is the difference between 50 units and 80 units?

50 units (25 units per side) is an appropriate dose for those with relatively mild symptoms, such as "a little sweaty in daily life" or "sweaty when nervous. It is also an easy choice for those who are trying Botox underarms for the first time or for those who want to keep costs as low as possible. However, for those with more severe symptoms, the effect may seem insufficient or the duration may be short.

On the other hand, 80 units or more (40 units or more per side) is the recommended dosage for those who are experiencing difficulty in their daily lives, such as "clear sweat stains on shirts" and "reapplication of antiperspirants several times a day. It approaches a wider range of sweat glands and is expected to have a strong antiperspirant effect and a long duration of use. In addition, people with large build and large underarm area, such as men, often need this amount to obtain sufficient effect.

How do you decide the first time? The Process of Determining the Number of Credits You Will Not Regret

When you are undergoing Botox underarms for the first time, it is difficult to determine for yourself how many units are best for you. The most important factor here is an accurate diagnosis by an experienced physician. The doctor will objectively evaluate the amount and extent of sweating through a consultation interview, visual examination, and possibly a sweating test (e.g., iodine paper method).

Many clinics take a stepwise approach, starting with a standard dose (e.g., 80 units) for the first time and then performing additional injections (touch-ups) 2 to 4 weeks later if the effect is insufficient. This is a very reasonable approach to achieve the maximum effect with the minimum amount needed.

What about after the second time? Adjustment of the number of credits for repeats

Botox underarms is a treatment that shows its true value with continued use; for the second and subsequent treatments, a more optimized treatment plan can be developed for you based on the results of the previous session.

(1) Feedback on previous effectiveness

Tell your doctor specifically what you felt about your last treatment, such as, "The last 80 units were perfect for the summer," "I need more duration," or "50 units may be sufficient for the winter." This feedback will be the most valuable information in determining the number of units for your next visit.

(2) Plan from a long-term perspective

Will you have the treatment at the same time each year or at a time when you are concerned about the amount of sweating you are experiencing? Discuss a long-term treatment plan with your doctor that fits your lifestyle.

(iii) Remembering the risk of antibody formation

As mentioned in the previous section, it is not recommended to repeat treatments at intervals of less than 4 months in order to maintain effectiveness. The formation of antibodies may render the treatment ineffective. Adhering to the proper intervals is the key to a long-lasting treatment as a result.

 

What are the effects on underarm odor? What can and cannot be expected from Botox underarms

In the previous chapters, we have explained that Botox underarms is a powerful treatment that dramatically reduces the "amount" of perspiration. However, many people who suffer from sweating are concerned at the same time about the "smell" problem that occurs along with sweat spots. Many people expect that "if Botox can stop sweating, won't it also eliminate the smell of armpit odor?" Many people are hoping that "if Botox underarms stop sweating, the smell of armpit cancer will disappear too.

Here, we answer that question head-on. We will unravel the fundamental relationship between sweat volume and odor, and clarify what effect Botox Underarms can have on odor, and where its limitations lie. A proper understanding of the treatment is the first step in achieving satisfaction.

Proper understanding of sweat volume and odor mechanisms

To understand the effects of Botox on underarm odor, we must first understand why a particular odor occurs from the underarms. The cause of the odor is not sweat itself. The key factors are the two types of sweat glands mentioned in Chapter 1 and the indigenous bacteria of the skin.

• Eccrine sweat glands: Distributed throughout the body, the 99% component secretes a watery, dry sweat. It is mainly responsible for the regulation of body temperature, and the sweat itself is almost odorless. Underarm Botox mainly acts on these eccrine sweat glands.
• Apocrine sweat glands: present in certain areas, such as the armpits and pubic area, secrete a slightly whitish, cloudy sweat that contains lipids and proteins. This sweat is also odorless immediately after it is produced. However, when the components in this sweat are decomposed by indigenous bacteria on the surface of the skin, odor substances characteristic of armpit sweat are generated.

In other words, the direct cause of odor is the combination of "sweat from apocrine sweat glands + indigenous skin bacteria. Then, why can Botox underarms, which mainly acts on eccrine sweat glands, be expected to have an effect on odor as well? It is because the "amount" of sweat from the eccrine sweat gland is reduced, which creates a secondary deodorant effect.

When the amount of sweat is reduced, the underarms are less likely to be hot and humid, making it more difficult for bacteria to grow. This suppression of fungal activity results in the suppression of odor from apocrine sweat.

Limitations and Realistic Expectations of Botox Underarms

Botox is not a panacea for odor. The purpose of "antiperspirant" (to control perspiration) and "deodorant" (to eliminate odor) are different. Understanding this difference and having realistic expectations will lead to satisfaction with the treatment.

1) Why it is effective for mild arousal

Botox can be a very effective option for those with relatively mild armpit cancer, where "the smell is a little bothersome when sweating.

As mentioned above, the amount of sweat is reduced and the underarms are kept dry, which in many cases suppresses the growth of bacteria and greatly reduces odor. For those who are concerned about both perspiration and odor, this product can be expected to kill two birds with one stone.

(2) Consider other treatment options for severe armpits.

On the other hand, if you have severe armpit odor (axillary odor) that is clearly strong on your own or other senses, it may be difficult to achieve satisfactory results with Botox underarms alone.

This is because Botox does not directly stop the activity of apocrine sweat glands, the cause of the odor, so even if the amount of sweat is reduced, the underlying cause of the odor remains. In such cases, more fundamental arachnoid treatment such as MiraDry or surgery (pruning method, etc.), which destroys or removes the apocrine sweat glands themselves, is recommended.

 

summary

Here we have provided a comprehensive explanation of when the effects of Botox underarms begin to appear, how long they last, how to choose the appropriate number of units for your symptoms, and the effects on the odor that many people are concerned about. We hope you have found that the signs of effectiveness begin to appear 2-3 days after treatment, stabilize in about 2 weeks, and that you can be free from sweating problems for 4-6 months after a single treatment.

The key is to develop the best treatment plan in consultation with a physician based on your symptoms and lifestyle. 50 or 80 units of options are available, and a diagnosis by a physician with specialized knowledge and experience is essential to obtain the maximum benefit at the minimum cost.

Botox underarms is a very effective treatment that dramatically improves the quality of life for those suffering from hyperhidrosis.
