Everything You Need to Know About Underarm Botox


Sweating is a natural and essential bodily function, but for some people, it can be excessive and problematic. If you’re one of those individuals who struggle with hyperhidrosis (excessive sweating), especially in the underarm area, you might be interested in learning about a highly effective solution: underarm Botox.

I am Dr. Jessica Wright and in this blog post, I explore what underarm Botox is, how it works, and what you can expect from the procedure. Y’all, I get this procedure for sheer convenience. I don’t have hyperhidrosis, but I do not like to use deodorant and I don’t use toxic anti-perspirant EVER!

What is Underarm Botox?

Botox, short for botulinum toxin, is a neurotoxic protein that has been used for various medical and cosmetic purposes for decades. While it’s widely known for its wrinkle-reducing capabilities, Botox is also FDA-approved for treating hyperhidrosis. Underarm Botox involves injecting small amounts of botulinum toxin into the skin of the armpits to temporarily block the nerves responsible for activating sweat glands. Many patients get it for simply a confidence booster.

How Does It Underarm BotoxWork?

When Botox is injected into the underarm area, it blocks the chemical signals from the nerves that stimulate the sweat glands. This effectively reduces the amount of sweat produced. The treatment doesn’t affect sweating elsewhere on the body, so your overall ability to sweat and regulate body temperature remains intact.

The Underarm Botox Procedure

The process of receiving underarm Botox is relatively quick and straightforward:

1. Consultation: You’ll start with a consultation with a healthcare provider to discuss your sweating concerns, medical history, and any potential risks or contraindications. This can be done right before your treatment, or you can do the consultation and think about it… We are cool with either!!

2. Preparation: On the day of the procedure, the treatment area will be cleaned and possibly numbed with a topical anesthetic to minimize discomfort. I like to ice the area to numb the skin and find that works well with our amazing itty-bitty needles.

3. Injection: Using a fine needle, the provider will administer multiple small injections of Botox into the underarm area. The entire procedure typically takes about 20-30 minutes.

Beth, Dana, Tami, Ola, Candice, and I all do this procedure frequently. I still have patients tell me they haven’t heard of it, so I decided to write this blog!

4. Post-Treatment Care: After the injections, you can resume most of your daily activities immediately. However, it's advisable to avoid strenuous exercise and hot environments for the first 24-48 hours. Try not to sweat too much during this time. This helps the longevity of your Botox treatment.

Results and Effectiveness

Most people start to notice a reduction in underarm sweating within a few days of treatment, with full results becoming apparent after about two weeks. The effects of underarm Botox typically last between 4 to 6 months, after which you can choose to repeat the procedure if desired. To be completely honest, Y’all know I am always brutally honest, most patients only do this in the summer.


Reduced Sweating: Significantly decreases underarm sweating, helping you stay dry and comfortable.
Improved Confidence: Less worry about visible sweat stains and odor can boost your self-esteem.
Non-Surgical: The procedure is minimally invasive and requires no downtime.

Potential Side Effects

While underarm Botox is generally safe, some people may experience mild side effects, such as:
– Pain or bruising at the injection site
– Headache
– Temporary muscle weakness near the treated area

These side effects are usually short-lived and resolve on their own. We only see them about 1-2% of the time. We treat lots of patients, so we get a good idea of complication rate.

Is It Right for You?

Underarm Botox is an excellent option for individuals who suffer from excessive underarm sweating and haven’t found relief with antiperspirants or other treatments. It’s important to consult with a qualified healthcare provider to determine if this treatment is suitable for you, especially if you have any underlying health conditions. Just to re-emphasis, we do this treatment frequently for people who sweat normally.


Underarm Botox can be a life-changing solution for those who struggle with hyperhidrosis. By effectively reducing excessive sweating, it allows you to feel more confident and comfortable in your daily life.
