How Does Botox for Excessive Sweating Reduce Sweat?
Botox for excessive sweating works by injecting botulinum toxin near the nerve endings of overactive sweat glands, temporarily blocking signal transmission between the nerves and the sweat glands. Its mechanism differs from that of wrinkle and masseter Botox, which relax muscles, and the target is the eccrine sweat gland rather than muscle.
It is mainly applied to the underarms, and is also used on other areas where sweating is concentrated, such as the palms, soles and forehead. Sweat volume begins to decrease within a few days after treatment, and the effect generally lasts for several months. However, how long it lasts varies with an individual's metabolic rate and activity level.

What Should You Generally Check Before Treatment?
Before getting Botox for excessive sweating, check the items below yourself or tell the doctor about them at the consultation.
- Pregnancy or breastfeeding: The effects of botulinum toxin on a fetus or newborn have not been sufficiently studied, so treatment is not recommended.
- History of neuromuscular disease: Neuromuscular junction disorders such as myasthenia gravis and Lambert-Eaton syndrome may be contraindications.
- Use of antibiotics or anticoagulants: Aminoglycoside antibiotics can amplify the effect of Botox, and anticoagulants raise the risk of bleeding.
- History of allergies: If you have a history of hypersensitivity to botulinum toxin products or their additives, it generally needs to be disclosed beforehand.
- Condition on the day of treatment: Areas with skin infection or inflammation are excluded from treatment or the schedule is adjusted.
What Side Effects Can Occur After Treatment?
Botox for excessive sweating is a relatively localized procedure, but it helps to know in advance what reactions can occur.
- Bruising or swelling at the injection site: Most of it disappears naturally within a few days.
- Temporary pain or a foreign-body sensation: This may appear for a short time right after the injection.
- Compensatory sweating: When underarm sweat is suppressed, a temporary increase in sweating in other areas such as the abdomen and back has been reported. The degree varies from person to person.
- Variation in effect: The reduction in sweating may feel different between the two underarms, and a touch-up injection may be considered at a return visit.
- Rare systemic reactions: Although very rare, if a headache or general weakness appears, contact the clinic immediately.

How Does Repic Clinic in Gangnam Design Botox Treatment?
Repic Clinic in Gangnam takes as its operating standard the approach of obtaining individual data through a diagnosis before treatment, after which the doctor designs the treatment plan directly. It does not apply a uniform protocol as is, and adjusts the number of injection points and the dose according to the area, range and intensity of sweating.
When combination treatment is needed beyond Botox alone, whether to combine it with lifting, filler or skin care is reviewed through a consultation. Using the Mark-Vu skin analysis device and the Meta View 3D diagnostic system to track data before and after treatment is also a feature of how this clinic operates.
At Repic Clinic in Gangnam, located at 318 Gangnam-daero, Gangnam-gu, Seoul, basement levels 1 and 2, you can also be given detailed plans for Botox treatment related to excessive sweating through a consultation.

How Should You Care for the Area After Treatment?
- Avoid vigorous exercise and saunas on the day of treatment. A rise in body temperature may affect how botulinum toxin spreads.
- Avoid strongly rubbing or pressing the treated area.
- It may take a few days for the effect to begin, so do not make your own plans to repeat treatment just because there is no immediate effect.
- It is usual to adjust the next treatment cycle around the time the effect begins to wear off.
