How Botox Can Help Your Excessive Sweating (Hyperhidrosis)
Want to address excessive sweating in a no-sweat way? Consider Botox®. This minimally invasive treatment can deliver months of drier skin. 

If you sweat a lot, summer can be a brutal time of year. You might have spent the last few months avoiding certain situations or clothing items to try to steer clear of unwanted wetness. 

Everyone sweats, but if this bodily function feels bothersome for you, you might be dealing with hyperhidrosis (excessive sweating). 

Michelle Fiore, M.D., and certified physician assistant Reema Patel, MPA, PA-C, have a solution that may help you. Here at Fiore Dermatology in San Carlos, California, we offer Botox® for individuals who sweat excessively. 

Let’s look at a few indicators that you should talk with us about this option. 

Signs you have hyperhidrosis

Sweat is your body’s way to cool itself down. It’s not just normal to sweat; it’s healthy. But that’s true when your body gets too hot, like when you’re working out or in a warm environment. 

If you notice that you sweat outside of “normal” times, you might have hyperhidrosis. If you sweat even when you’re resting or cold, for example, it’s a sign you’re dealing with this condition. 

Typically, excessive sweating affects your:

  • Hands
  • Underarms
  • Face
  • Feet

The hands are a particularly common area for hyperhidrosis. 

Think back on the summer. Were you sweating a lot because of heat exposure or exertion? If you notice sweating that isn’t triggered by heat or physical activity — and it’s frequent enough to interfere with your daily life — you may be experiencing hyperhidrosis. 

Come see Dr. Fiore to get more information. She can help you determine if you’re living with medically diagnosable excessive sweating. 

How Botox can help

If you do have hyperhidrosis, Botox can help. 

This is the same injectable people use to address wrinkles. When injected into areas where you experience excessive sweating, it can block the nerve signals that tell your sweat glands to kick into gear. 

Recent research showed that using Botox for hyperhidrosis delivered a number of benefits, including:

  • Reduced sweating
  • Improvement within one week that lasted up to six months
  • Quality of life improvements
  • Improved emotional well-being

As an added perk, Botox is a quick and convenient treatment. Injecting it only takes about 10 minutes, and there’s no downtime afterward. You will require several injections, but the needle is extremely fine, and we can provide a numbing agent beforehand. 

If Botox provides you with meaningful relief, Dr. Fiore and our team can repeat treatment as needed to maintain your results.
