How Anti-Sweat Injections Work: Botox for Sweating Explained
Sweating is normal, but for some, it goes far beyond what’s needed to regulate body temperature. You’re not alone if you’re tired of feeling uncomfortable, constantly changing clothes, or avoiding social situations due to excess sweat.
Thankfully, there’s a solution that doesn’t involve surgery or endless deodorants. Anti-sweat injections are becoming a trusted and effective option for those seeking relief.
Let’s Get Straight To The Point
Anti-sweat injections offer a safe, fast, and minimally painful solution for people who sweat too much. They block the nerve signals that trigger sweat glands, giving long-lasting dryness, often for months.
The anti-sweat injection process takes less than an hour, has almost no downtime, and shows noticeable results within days.
It’s used in common problem areas like underarms, palms, and feet. If excessive sweating affects your daily life, this injection-based sweating solution might be what you need.
What Causes Excessive Sweating?
Excessive sweating, or hyperhidrosis, isn’t just about feeling hot. It’s often caused by overactive nerves that tell your sweat glands to switch on, even when they don’t need to.
This condition can be:
- Primary: No apparent cause; often affects hands, feet, underarms, and face.
- Secondary: Caused by medications, infections, or medical conditions.
People living with hyperhidrosis often find that it affects their work, relationships, and confidence. For some, it’s so severe they carry spare clothes everywhere or avoid social contact entirely.
How Sweat Injections Work
Sweating injections block the signals between nerves and sweat glands.
The injectable, commonly used in cosmetic procedures, acts on the sweat glands in the treated area. Once the connection is blocked, sweat production drops significantly.
These injections are especially effective in:
- Underarms (most common)
- Palms and soles of the feet
- Face and scalp
Because the treatment is local, sweating stops only in the areas treated, making it a safe and targeted solution.
The Anti-Sweat Injection Process
The procedure is quick and low-fuss. You’ll usually be in and out in under an hour.
Here’s what the anti-sweat injection process looks like:
- The area is cleaned and marked.
- A topical numbing cream might be applied (especially for palms or feet).
- Tiny injections are placed just under the skin using a fine needle.
- Done. You’re good to go.
Some mild redness or swelling is normal, but most people return to normal activities immediately.
What to Expect from Injections
Don’t expect to leave completely dry, but don’t worry, it’s coming.
Here’s what to expect from injections:
- Minor discomfort: Feels like tiny pinpricks.
- No downtime: You can usually drive yourself home.
- No workout or sauna for 24 hours.
- Visible dryness in the area within 2–7 days.
Depending on how your body responds, follow-up may be needed. Some people get a top-up after a few weeks.
Timeline for Injection Results
You won’t need to wait long.
The timeline for injection results is generally:
- Day 2–3: Slight drop in sweating.
- Day 4–7: Noticeable dryness begins.
- By week 2: Full results are in.
The dryness usually lasts 4 to 6 months. After that, the nerves slowly reconnect, and sweat may return. You can repeat the treatment as needed.
How Injections Stop Perspiration Without Harming the Body
It’s normal to wonder if stopping sweat is terrible; the answer is no when done correctly.
These injections only work where applied. You still usually sweat elsewhere, which is how your body cools itself. That’s why it’s a safe, local solution for overly sweaty zones.
You won’t get overheated, and there’s no risk of sweat “building up” in your body.
How to Prepare for Your First Sweat Injection Appointment
Proper prep is key to getting the most out of your treatment. If this is your first time, here’s what you must do to prepare and ensure the anti-sweat injection process goes smoothly.
A Few Days Before:
- Avoid blood thinners like aspirin, fish oil, or anti-inflammatory meds (unless prescribed).
- Shave the treatment area 24–48 hours before (especially underarms).
- Avoid deodorant or lotions on the day of the appointment.
On the Day:
- Wear loose, comfortable clothing.
- Bring a list of any medications or medical conditions.
- Let your provider know if you feel unwell or have an infection near the treatment site.
Mentally prepare:
- The procedure is short and tolerable.
- Some people describe the feeling as quick stings or pinches.
- You’ll likely be done within 30 to 45 minutes.
Following this prep helps reduce bruising, swelling, or irritation and allows the product to work effectively.

Some even report better sleep because they’re not waking up sweaty.
The change can feel like significant relief if you’ve struggled with embarrassment or discomfort.
Are There Any Side Effects?
The risk is low when trained professionals do the treatment.
Some temporary side effects can include:
- Swelling or bruising at injection sites
- Mild tenderness

- Muscle weakness (very rare and typically with improper application)
If something feels off, always check in with your provider.
How Long Does Treatment Last?
Most people enjoy dryness for 4 to 6 months. Some may get longer, depending on how their body reacts. Over time, your sweat response may become less intense even as the treatment wears off.
Maintenance treatments are recommended twice a year for best results.

What You Should Ask Before Getting the Injections

- Is this the proper treatment for my type of sweating?
- How many treatments have you done?
- What areas do you specialise in treating?
- What happens if I don’t see results?
- What aftercare do I need?
