Most people know Botox as the go-to treatment for wrinkles.
But what many don’t know is that it’s also FDA-approved for hyperhidrosis – the medical term for excessive sweating.
If you’re someone who dreads sweat patches on shirts, struggles with clammy hands, or avoids social situations out of embarrassment, this might be the solution you’ve been looking for.

What is Hyperhidrosis?
Hyperhidrosis is when you sweat excessively without triggers like heat or exercise. It often affects the underarms, palms, soles, or face. Regular antiperspirants and creams usually don’t help much, leaving people frustrated.
This condition can interfere with daily life — from shaking hands confidently to wearing your favorite clothes without worry.
For many, it’s more than just a physical issue; it deeply affects social comfort and self-esteem.
How Does Botox Work?
Sweating happens when nerves tell your sweat glands to activate. Botox temporarily blocks these signals, reducing sweat production in the treated area.
Think of it like hitting the “pause button” on your sweat glands.
The result?
Noticeably drier skin in just a few days, with effects that can last several months. It’s a targeted solution that brings relief where you need it most, without affecting your body’s natural cooling in other areas.
Safety and Effectiveness
Botox for sweating is safe and effective when done by a qualified dermatologist. The FDA approved it for underarm sweating in 2004, and it’s been used worldwide ever since. Side effects are usually minor, like slight soreness or temporary weakness in hand muscles (if palms are treated).
With millions of treatments performed globally, Botox has a proven track record of delivering consistent results. When handled by experts, the procedure is quick, minimally invasive, and requires virtually no downtime.
How Long Do Results Last?
- Starts Working: Within 2–7 days.
- Peak Results: Around 2 weeks post-treatment.
- Lasts: 4–12 months, depending on your body.
- Maintenance: Repeat sessions are needed when sweating returns.
Who Should Consider It?
- People with primary hyperhidrosis are not linked to another medical issue.
- Those who’ve tried and failed with strong antiperspirants or oral meds.
- Anyone seeking a quick, non-surgical solution with minimal downtime.
FAQs People Often Ask
- Will I stop sweating completely? No, you’ll just stop sweating excessively in the treated area. Your body still sweats elsewhere to regulate temperature.
- Is it painful? Discomfort is minimal. A numbing cream or ice can make the injections more comfortable.
- Is it permanent? No. Results fade gradually, so maintenance is needed.
