Quick Answer
Sweat Botox (hyperhidrosis Botox) is the injection of botulinum toxin type A into areas with high concentrations of sweat glands to treat excessive sweating. The toxin blocks the release of acetylcholine that stimulates sweat glands, reducing sweating by 80–90%. The procedure takes 15–30 minutes, effects begin within 3–7 days and last 6–12 months depending on the area. This FDA-approved treatment can be applied to multiple areas including the underarms, palms, soles, forehead and scalp. You can review the general mechanism of botulinum toxin in our detailed Botox guide.

What Is Sweat Botox (Hyperhidrosis Botox)?
Sweat Botox, medically known as hyperhidrosis botulinum toxin therapy, is a minimally invasive procedure that resolves excessive sweating without surgical intervention. Botulinum toxin type A is injected under the skin with fine needles, blocking the release of acetylcholine from nerve endings. Acetylcholine is the primary neurotransmitter that activates eccrine sweat glands; blocking this chemical stops gland stimulation and significantly reduces sweating in the treated area.
According to data from the International Hyperhidrosis Society (IHHS), a significant reduction in sweat production is observed in 82–87% of patients following botulinum toxin treatment. The U.S. Food and Drug Administration (FDA) officially approved botulinum toxin for axillary (underarm) hyperhidrosis treatment in 2004.
How Does Sweat Botox Work?
The mechanism of sweat Botox works step by step as follows:
- Injection: Botulinum toxin is injected intradermally (under the skin) with fine needles
- Binding to nerve endings: The toxin binds to SNARE proteins at cholinergic nerve endings
- Acetylcholine blockade: Release of acetylcholine vesicles from nerve endings is prevented
- Eccrine gland inactivation: Eccrine sweat glands that receive no stimulus cease sweating
- Temporary effect: Nerve endings gradually form new connections and return to function (6–12 months)
Important: Sweat Botox does not disrupt the body's general thermoregulation mechanism. It only affects the sweat glands in the treated area; the body maintains normal sweating balance through other areas.

What Is Hyperhidrosis (Excessive Sweating)?
Hyperhidrosis is the production of far more sweat than the body needs for temperature regulation. While an average person produces about 0.5–1 litre of sweat per day, in hyperhidrosis patients this amount can be 4–5 times higher. Approximately 3–5% of the world population is affected by this condition.
Difference Between Primary and Secondary Hyperhidrosis
| Feature | Primary Hyperhidrosis | Secondary Hyperhidrosis |
|---|---|---|
| Cause | No known underlying disease | Related to another disease or medication |
| Age of onset | Childhood or adolescence | Can begin at any age |
| Affected area | Usually symmetric (both underarms, both palms) | Can be widespread or asymmetric |
| Night sweating | Generally absent | Frequently accompanies |
| Family history | Positive in 30–50% of patients | Generally absent |
| Treatment approach | Sweat Botox is first-line treatment | Treat underlying cause first |
| Frequency | 90% of hyperhidrosis cases | 10% of hyperhidrosis cases |
Primary hyperhidrosis most commonly affects the underarms (51%), palms (25%), soles (20%) and face (5%). Genetic predisposition is a strong factor; those with a first-degree relative with a history of hyperhidrosis have a 5-fold higher risk.
Symptoms of Hyperhidrosis
- Experiencing excessive sweating episodes at least once per week
- Sweating negatively affecting daily activities (writing, gripping the steering wheel)
- Bilateral and symmetric sweating
- Sweating stopping or reducing during sleep (in primary type)
- Onset before age 25
- Positive family history
If four or more of these symptoms are present, a diagnosis of primary hyperhidrosis can be made with high probability.

Which Areas Can Sweat Botox Be Applied To?
Sweat Botox can be applied to various areas of the body. Each area has its own application protocol, efficacy rate and comfort level.
| Treatment Area | Recommended Dose (Units) | Duration of Effect | Pain Level | Efficacy Rate | Special Note |
|---|---|---|---|---|---|
| Underarms | 50–100 U per side | 8–12 months | Low | 90–95% | Highest patient satisfaction |
| Palms | 50–100 U per side | 6–9 months | High | 80–90% | Nerve block or ice anesthesia recommended |
| Soles of feet | 50–100 U per side | 6–9 months | High | 80–85% | Focus on heel and forefoot |
| Forehead | 20–40 U total | 4–6 months | Low–Medium | 85–90% | Brow ptosis risk assessed carefully |
| Scalp | 50–100 U total | 4–8 months | Low | 80–85% | Also known as blow-dry Botox |
| Groin area | Variable | 6–8 months | Medium | 75–85% | Less common application |
Underarm Sweat Botox
The underarm is the area where sweat Botox is applied most frequently and most effectively. The fact that it is the only area with official FDA approval strengthens its clinical evidence level. Because eccrine gland density is high in the underarm, botulinum toxin injections provide 90–95% reduction in sweating. The duration of effect is longer compared to other areas: an average of 8–12 months.
Palm Sweat Botox
Palmar hyperhidrosis is the type of sweating that most affects social and professional life. Problems such as inability to shake hands or hold paper cause significant anxiety. Palm injections are more painful because this area has a high nerve density. For this reason, comfort is increased by applying ulnar and median nerve block or ice anesthesia.
Sole Sweat Botox
Excessive sweating of the soles creates a breeding ground for fungal infections and bad odor. The injection technique requires special attention due to the thick dermal structure. Generally the heel, forefoot and interdigital areas are targeted.
Forehead and Scalp Sweat Botox
Forehead sweat Botox is preferred particularly in patients who complain of makeup running or sweat getting into the eyes. Scalp Botox has gained popularity in recent years as "blow-dry Botox"; it prevents the hair from becoming oily quickly and losing its shape due to sweating.

How Is Sweat Botox Applied? (Step by Step)
Sweat Botox application is a systematic process carried out in a clinical setting by an experienced physician.
1. Consultation and Assessment
- The patient's sweating history is taken in detail
- Degree of sweating is determined using the Hyperhidrosis Disease Severity Scale (HDSS)
- Underlying conditions (thyroid, diabetes, menopause) are excluded
- Current medications are reviewed
2. Iodine-Starch Test (Minor Test)
- Iodine solution is applied to the sweating area
- After drying, starch powder is dusted over it
- Points where sweating occurs turn dark purple-black
- This color change precisely maps the active sweat gland points for injection
- Prevents unnecessary injections and optimizes the dose
3. Anesthesia (as Needed)
- In the underarm, anesthesia is generally not needed or topical cream is sufficient
- For palms and soles, nerve block, ice anesthesia or topical anesthetic cream is applied
- Some clinics use vibration anesthesia devices
4. Injection
- The designated area is marked in an injection grid pattern at 1–2 cm intervals
- 2–4 units of botulinum toxin are injected intradermally at each point
- Generally 15–20 injection points are used per underarm
- Fine 30–32 gauge needles are preferred
- Total procedure time is 15–30 minutes
5. Post-Procedure Check
- Patient is kept under observation for 15–20 minutes
- Cold compress may be applied to the treatment area
- Follow-up appointment is generally scheduled for 2 weeks later

How Many Units Are Needed for Sweat Botox?
The number of units required varies by treatment area, severity of sweating and the patient's body structure.
| Area | Minimum Dose | Average Dose | Maximum Dose | Number of Injection Points |
|---|---|---|---|---|
| Underarm (single side) | 50 U | 75 U | 100 U | 15–20 points |
| Underarms (both sides total) | 100 U | 150 U | 200 U | 30–40 points |
| Palm (single side) | 50 U | 75 U | 100 U | 20–25 points |
| Sole (single side) | 50 U | 75 U | 100 U | 20–30 points |
| Forehead | 20 U | 30 U | 40 U | 10–15 points |
| Scalp | 50 U | 75 U | 100 U | 20–30 points |
The total session dose generally should not exceed 400 units including all areas. The physician adjusts the dose based on the iodine-starch test result and the patient's response.

How Long Does Sweat Botox Last?
The duration of sweat Botox varies by treatment area, dose used and individual metabolism.
- Underarms: 8–12 months (longest duration)
- Palms: 6–9 months
- Soles: 6–9 months
- Forehead: 4–6 months
- Scalp: 4–8 months
Effects begin to be felt within 3–7 days and reach their maximum level within 2–4 weeks. Research shows that in patients who receive regular treatment, the duration of effect may extend over time; in some patients after the 3rd or 4th session, the effect can extend to 12–14 months.
Factors Affecting Duration of Effect
- Metabolic rate: People with faster metabolism may have shorter-lasting effects
- Physical activity level: Those who exercise intensely may require more frequent treatment
- Dose applied: Adequate dosing provides longer-lasting effects
- Area: Underarms have the longest, forehead the shortest duration
- Number of sessions: Regular treatments gradually extend the duration

Is Sweat Botox a Painful Procedure?
Pain perception varies significantly by treatment area:
| Area | Pain Level (1–10) | Anesthesia Need | Description |
|---|---|---|---|
| Underarms | 2–3 (Low) | Generally not needed | Thin skin, low nerve density |
| Forehead | 3–4 (Low–Medium) | Topical cream sufficient | Similar comfort to cosmetic Botox |
| Scalp | 2–3 (Low) | Generally not needed | Numbing effect of hair follicles |
| Palms | 6–8 (High) | Nerve block recommended | High nerve density |
| Soles | 6–8 (High) | Nerve block recommended | Thick skin, sensitive nerves |
Pain management techniques:
- Topical anesthetic cream: Applied 30–60 minutes before treatment (EMLA cream)
- Ice anesthesia: Ice applied to the area before injection
- Nerve block: Ulnar and median nerve block for palms
- Vibration anesthesia: Suppression of pain signals using vibration devices
- Fine needle use: 30–32 gauge needles minimize pain

Frequently Asked Questions (FAQ)
1. Is sweat Botox permanent?
No, sweat Botox is not permanent. The duration of effect varies between 6–12 months depending on the area. It lasts longest in the underarms (8–12 months) and shortest on the forehead (4–6 months). For a permanent solution, MiraDry (underarms only) may be an alternative. However, with regular treatments the duration of effect has been observed to extend over time.
2. Should sweat Botox be done in summer?
No, there is no seasonal restriction. However, strategically scheduling it before summer (April–May) ensures comfort throughout the summer months. Since effects begin in 3–7 days, treatment at least 1 week before the start of summer is recommended.
3. Does sweat Botox completely stop sweating?
In most patients sweating is reduced by 80–90%. Complete cessation is observed in some patients, but the primary goal is to reduce sweating to a level that does not affect daily life. Sweating in other areas of the body continues normally.
4. Can I exercise after sweat Botox?
Intense exercise should be avoided for the first 24 hours after treatment. After this period, normal physical activities can be resumed. Athletes who train intensely are advised to wait 48 hours.
5. Can sweat Botox and cosmetic Botox be done at the same time?
Yes, they can. Both wrinkle treatment and sweat Botox can be applied in the same session. However, physician evaluation is required to ensure the total unit count remains within safe limits. You can review cosmetic Botox details in our Botox guide.
6. Can sweat Botox be applied during pregnancy?
No, absolutely not. The use of botulinum toxin during pregnancy and breastfeeding is contraindicated. Women planning to become pregnant are advised to complete their last session at least 3 months before conception.
7. Does sweat Botox cause weight gain?
No, sweat Botox does not cause weight gain. Botulinum toxin acts only locally and does not affect metabolism, appetite or hormonal balance. The amount of fluid lost through reduced sweating is negligible.
8. Does sweat Botox also prevent body odor?
Partially, yes. Underarm odor results from the interaction of sweat with bacteria. As sweating decreases, bacterial proliferation also decreases and odor noticeably diminishes. However, odor originating from apocrine glands may not be completely eliminated.
9. Are there long-term risks of sweat Botox?
No serious long-term risks have been reported. Botulinum toxin has a well-documented safety profile with over 30 years of clinical use. Repeated applications do not cause structural damage to sweat glands. However, in very rare cases (1–3%), antibody development over time may reduce effectiveness.
10. Which doctor performs sweat Botox?
Sweat Botox can be performed by dermatology specialists, plastic surgery specialists and physicians with medical aesthetics training. The most important criterion is that the physician is experienced in botulinum toxin administration.
11. Is there a difference between brands used for sweat Botox?
Yes. The most commonly used botulinum toxin brands are Allergan Botox, Dysport (Galderma) and Xeomin (Merz); their efficacy has been found comparable in clinical studies. Dose equivalences differ: 1 unit of Botox corresponds to approximately 2.5–3 units of Dysport. Brand selection is determined by the physician's experience and the patient's previous response.
12. Does sweat Botox show full effect in the first session?
Generally yes, but in some patients the response in the first session may be partial. In this case, touch-up injections can be performed at the 2-week follow-up appointment. In the second and subsequent sessions, the physician knows the patient's response profile and achieves more optimal results.
13. Does sweating increase in other areas after sweat Botox?
This phenomenon known as compensatory sweating occurs in approximately 5–10% of patients and is generally mild. The body may try to compensate for reduced sweating in the treated area from other areas. However, compared to surgical sympathectomy (ETS), this is much rarer and milder with sweat Botox.
14. When should sweat Botox be repeated?
The timing of repetition is determined by when sweating resumes. As a general rule:
- Underarms: Every 8–12 months
- Palms: Every 6–9 months
- Soles: Every 6–9 months
It is recommended to book an appointment when the effect begins to diminish rather than waiting for sweating to return completely to its previous state. This approach provides continuous comfort and may contribute to extending the interval between sessions.
