Botulinum toxin for excessive sweating
Underarms, hands, feet or forehead: for excessive sweating, botulinum toxin can significantly reduce sweat production for several months.

Why patients come to me
Your concern
You sweat much more than temperature or effort can explain. Under your arms that means stains on clothes, on your hands damp handshakes and slipping pens, on your feet wet shoes, on your face beads of sweat on your forehead, even at rest.
The treatment
Botulinum toxin is placed superficially into the skin of the affected area with very fine needles. There it blocks the signals to the sweat glands. Underarms are quick to treat; hands and feet need more injection points, so I use cooling.
Possible result
Sweat production in the treated area can drop significantly within a few days. Under the arms the effect often lasts 4 to 6 months, on hands and feet often a little shorter.
Prices
Underarms have a fixed guide price. For hands, feet and forehead the amount depends heavily on the area, so I'll give you the price after the consultation. Several areas in one session can be agreed as a package.

I assess your facial expressions, we set the goal together, and I treat using very fine needles. Duration: 20 to 45 minutes. You can go straight back to your day.

Top up if you like
The body breaks the product down and the effect wears off. Whether and when you top up is your decision.

Marvin Jeromin, physician
I'm a licensed physician and the founder of BTXRoom in Berlin-Charlottenburg. Before every treatment I take time to understand your face: expressions, structure, proportions. Only then do I decide which treatment and dose suit you. My goal is a natural, balanced result.
More about meWhat patients say
Excerpts from Google reviews of BTXRoom, translated from German.
“I had a Botox treatment with Mr Jeromin and I'm thrilled. The consultation was professional and empathetic, the treatment quick and painless, and the result natural, just as I wanted. Clear recommendation, I'll be back!”
“I had my first Botox treatment here and was very satisfied with the treatment and the result. It was important to me not to look unnatural afterwards. Marvin advised me perfectly and made me feel good. Thank you, I'll gladly come back 🙏”
When it counts as hyperhidrosis
When sweating goes well beyond the normal level and noticeably affects everyday life. Primary hyperhidrosis typically affects specific areas such as the underarms, hands, feet or forehead. In the consultation we clarify whether other causes should be checked by a doctor.
Cost coverage
The treatment is self-pay. Some private health insurers contribute if it's medically necessary. Check this with your insurer beforehand.
Frequently asked questions
Which areas can be treated?
Most often the underarms. Also the palms, the soles of the feet and the forehead with hairline. Which areas make sense for you, we discuss in the consultation.
Does it hurt?
Under the arms most people find the fine injections easy to tolerate. Palms and soles are more sensitive, so I cool the skin during the treatment.
Can I grip normally after treating my hands?
For the first few weeks, fine movements such as writing can feel slightly weaker. This wears off. If your work depends on fine manual tasks, let me know.
Will I sweat more elsewhere?
The treatment works locally. Compensatory sweating in other areas is rare after this treatment.
What should I keep in mind afterwards?
Don't massage the treated area and avoid intense exercise, sauna and strong sun for 24 hours. After a forehead treatment, also stay upright for about 4 hours.
How does the follow-up work?
After 14 days we look at the result together. If a small adjustment is needed, it's included in the price.
