Botox for Sweating (Hyperhidrosis) in Mersin: Who It Suits, How Long It Lasts, Is It Painful?

Botox for sweating (hyperhidrosis) works by temporarily blocking the nerve signals that stimulate the sweat glands and can significantly reduce excessive sweating; it is most often applied to the underarms, palms and soles. In Mersin, botulinum toxin treatments, including treatment for sweating, are performed by medical doctor Dr. Doğan Uysal at the clinic in Mezitli. This article answers the questions asked most often: who it suits, how it is done, how long it lasts, whether it is painful and who should not have it.

Who Is Botox for Hyperhidrosis Suitable For?

Botox for sweating is considered for primary hyperhidrosis, in which no cause can be found and which affects daily life. Hyperhidrosis is sweating beyond what the body needs for temperature regulation and can have a marked effect on quality of life; the primary form is mostly focal and has no identifiable cause (idiopathic), whereas the secondary form is commonly generalised and caused by an underlying medical condition or the use of medications (Nawrocki and Cha, 2020). For sweating that affects social life, botulinum toxin is one of the treatments frequently sought; suitability is determined at the examination.

Does Botox for Sweating Replace First-Line Treatments?

Generally not; botulinum toxin is usually considered after the first steps. Botulinum toxin injections are widely used as a second-line option once topical treatments (applied to the skin) have not been enough, and in small doses they are described as one of the most effective therapies for primary hyperhidrosis (Nawrocki and Cha, 2020). In a meta-analysis of underarm studies, botulinum toxin gave sweat reduction comparable to the other treatments it was compared with (Sun et al., 2025). So botulinum toxin is not a replacement for the other options; it is a step chosen when it suits your complaint and your earlier experience.

How Is Botox for Sweating Done, and What to Expect?

The process consists of a few steps that start with an examination:

1. 1Examination and planning: An examination is carried out before treatment; your medical history and the medications you use are reviewed, and the area (underarms, palms or soles) and the dose are planned individually.
2. 2Treatment: Botulinum toxin is injected with fine needles; a topical numbing cream can be applied to sensitive areas.
3. 3First days: Mild redness, tenderness and small bruises may appear; detailed aftercare instructions are shared after the appointment.
4. 4When the effect appears: With botulinum toxin treatments the effect usually begins in 3–5 days and the full effect appears in 10–14 days; small corrections are made at the follow-up visit if needed. For the day-by-day course see our article on how many days until Botox takes effect.
5. 5When the effect wears off: The effect usually lasts 4–6 months; when it wears off the treatment can be repeated.

How Many Months Does Botox for Sweating Last? What Do Studies Show?

The effect of botox for sweating usually lasts 4–6 months, and the treatment can be repeated when it wears off. The most suitable timing is before summer; the effect can noticeably improve daily comfort, especially in the summer months. In studies, results and durations vary by area; the table below summarises the reviews cited in this article:

These figures are study results; at our clinic the average duration of effect for botulinum toxin is 4–6 months, and for you it may vary with the person, the area and the dose. The same review associated higher doses and repeated injections with longer-lasting control, reported a marked improvement in quality-of-life measures and found that patient satisfaction diminished over time (Eze et al., 2026). So botox for sweating is not a permanent solution but a temporary treatment that can be repeated.

Is Botox for Sweating Painful? Possible Side Effects

Injections are given with fine needles and a topical numbing cream can be applied to sensitive areas. In the meta-analysis of underarm studies the pain score of botulinum toxin injection was comparable to other treatments and side effects were fewer (Sun et al., 2025). For the palms, a systematic review notes that treatment was limited by injection discomfort and transient weakness (Farah et al., 2026), so expectations and possible weakness should be discussed before palm treatment.

Common, temporary side effects of botulinum toxin are redness, tenderness and small bruises at the injection points and a mild headache in the first days; rarely, infection or prolonged muscle weakness is reported. If you notice an unexpected, severe or prolonged symptom, contact the clinic; if you suspect an emergency, go to an emergency department without waiting. For urgent signs after treatment see our guide to counterfeit Botox.

Who Should Not Have Botox for Sweating, and When to See a Physician First?

Botulinum toxin is considered for people over 18 whose general health is suitable. In the following situations, treatment is postponed or not carried out:

• Pregnancy and breastfeeding
• Known allergy to botulinum toxin or to any of the product ingredients
• Neuromuscular conditions such as myasthenia gravis
• Active infection or inflammatory skin problem in the treatment area
• Bleeding disorders or regular use of blood thinners (planned with physician assessment)

If your sweating affects the whole body or may be linked to a medical condition or the use of medications, it is important that a physician assesses the cause before botulinum toxin is started, because secondary hyperhidrosis is commonly generalised and caused by an underlying medical condition or medication (Nawrocki and Cha, 2020). This information is general; the decision on suitability is made at a face-to-face examination, taking into account your medical history and the medications you use.

What to Ask When Choosing a Doctor

Botulinum toxin is a medical treatment; it should be performed by a physician and with Ministry of Health–approved products. Before deciding you can ask:

• The practitioner: Is the person performing the treatment a medical doctor?
• The product: Is the product approved by the Ministry of Health and how can its licence be checked? See our guide to counterfeit Botox for details.
• The assessment: Are your medical history and the medications you use reviewed, and are you asked when the sweating began and which methods you have already tried?
• The plan: Are the dose and the treated area planned individually at the consultation?
• Follow-up: Is there a follow-up visit to assess the result and a plan for repeating the treatment when the effect wears off?

At Dr. Doğan Uysal's clinic in Mezitli the answers are as follows: medical doctor Dr. Doğan Uysal performs the botulinum toxin treatment himself; he graduated from Mersin University Faculty of Medicine in 2017 and has worked in medical aesthetics since 2017. Treatments are carried out with products approved by the Turkish Ministry of Health, in a sterile environment and under physician supervision, with an individual dose plan; small corrections are made at the follow-up visit if needed and treatments that are not needed are not recommended.
