How Does Botox For Excessive Sweating Work?

Botox by B Medical Spa and Wellness Center in San Diego

It’s normal to sweat every day. We, humans, need to sweat to keep our bodies at the right temperature. But some people sweat a lot more than they need to. 

Today, B Medical Spa and Wellness Center explains how Botox can help you work with excessive sweating. If you’ve been experiencing this challenge for some time, this blog post might help you. Check out for more details. 

Too Much Sweating

Hyperhidrosis, or too much sweating, can significantly impact a person’s quality of life. Some people only sweat too much in one place on their body, like their underarms or feet. This is called focal hyperhidrosis. 

In other cases, sweating happens all over the body, not just in a few spots. The scalp, underarms, hands, feet, and groin area are the most common places where hyperhidrosis occurs.

Excessive sweating can have a significant effect on a person’s life. It can be embarrassing and make you feel alone; many people find it upsetting. So, Botox is often used to smooth out wrinkles. Still, it is also a very effective way to treat focal hyperhidrosis. 

Botox & Excessive Sweating

Botox injections contain botulinum toxin, which blocks the nerve signals that cause sweating. This keeps the sweat glands from making too much sweat. As the nerves heal, most people need to return in four to six months. Patients can, however, go longer between treatments as time goes on.

When Botox works, your body odor decreases too. But that doesn’t mean you won’t use deodorant or antiperspirant anymore. Botox injections reduce excessive sweating to an average or slightly less-than-normal amount. 

Most people still sweat a little and may need deodorant or antiperspirant. But it depends on the person. We know how effective Botox is and how the U.S. Food and Drug Administration (FDA) approves it to treat underarm hyperhidrosis.

But still, personal hygiene must be in place to fully see the treatment results. Still, Botox can be more painful and cause more side effects if you use it in the following areas:

  • Hands
  • Feet
  • Behind the chest
  • Head
  • Face

How Botox Functions To Stop Sweating?

Again, Botox works by blocking, for a short time, the chemicals that tell your sweat glands it’s time to make sweat. It doesn’t change how the underarm feels to touch or feel.

Most of the time, 25 injections are given in each armpit. Each time, your doctor will use a tiny needle to inject a small amount of Botox just under the skin’s surface.

The truth is, some people don’t even feel the shots. But if they do, they say it hurts more than it’s uncomfortable. It sounds like a rubber band snapping.

In about three to four days, you should notice that you sweat less. It takes about two weeks for the full, moisture-busting effects to happen.

In general, Botox is not only for beauty treatments. It also works for sweaty armpits and only takes one trip to the doctor’s office. 

How To Prepare For The Treatment?

Botox injections are a quick and easy process that can be done in your doctor’s office. Most doctors will ask you to wear a short-sleeved shirt and wait 2 or 3 days before shaving your armpits. 

If you take blood thinners, your doctor may ask you to stop for a few days before your injections to keep you from getting bruises. Tell your doctor about any medications you’re taking, and don’t stop unless your doctor tells you to.

Your doctor may also tell you to wear a dark shirt so you don’t get ink.

Botox Side Effects

Your body needs to sweat to cool down. So, if you get Botox injections in your armpits to stop sweating, does that prevent your body from cooling down? 

No, because there are only a small number of sweat glands in each part of your body that sweats. 2% of them are in your underarms. Your body’s ability to cool down won’t be affected if you stop sweating in a few small places.

People also worry that if they sweat less in one part of their body, they will sweat more in other regions. But that also doesn’t happen.

Botox injections in the armpits have almost no side effects other than the pain of the injections themselves. Muscle weakness is the most common side effect, but that’s more of a problem in places like the palms.

What To Expect After The Treatment?

After your surgery, you should be able to go home right away. Most of the time, only a little aftercare is needed. The area that was treated may hurt for the next day or so.

Once the Botox has full effect, your doctor will probably want to see you again about two weeks after your appointment. They usually tell people to stay away from deodorant or perfumed products under their arms for 12 to 24 hours to avoid irritation. 

For one to two days, staying away from intense exercise and hot baths may also help.

Our Botox Treatment 

At B Medical Spa and Wellness Center, Botox is a safe treatment. It takes about ten minutes to finish. Botox is injected into the muscle to make the wrinkles contract. 

This is done with a fine needle. The injection calms down the muscles that are being treated. Your skin gets smoother and less wrinkled. 

The effects of a single Botox treatment usually last between 3 and 4 months, but they can last longer with more treatments. Most of the time, results show up in four to ten days.

Stop your sweating problem (and other aging concerns) with the help of this treatment. 


We also have a Dysport service treatment here at the clinic, which you may like. The FDA has approved Dysport as a way to reduce the look of wrinkles through a minimally invasive procedure. 

The results are excellent and look natural. It was made as an alternative to Botox. It quickly removes those annoying lines without changing how the rest of your face looks or moves.

Where To Get Botox?

Botox injections can be done safely by a board-certified dermatologist. Look for a doctor who uses Botox to eliminate wrinkles and stop people from sweating too much. You want someone who knows about the treatment and any possible side effects.

Also, a qualified dermatologist knows who shouldn’t get Botox: People who take certain medications or have conditions like myasthenia gravis are usually not candidates.
