We all sweat, but a small percentage of the population does so profusely. Excessive sweating mainly occurs in the axilla apart from the soles of the feet and palms. Though the treatment options to correct this are quite unsatisfactory, botox treatments have been found to work well and successfully for a multitude.

In this post, we will be largely discussing what causes underarm sweating and how botox works to reduce the same. Read along to learn the benefits and drawbacks of botox, and what to expect when getting Botox injections.

What Causes Underarm Sweating?

Have you ever wondered why you continue to smell bad after a shower? It turns out that the problem is with your underarms. The term "apocrine glands" refers to the sweat glands that are located in the armpit. These glands secrete a fatty type of sweat, which is more likely to be released when the temperature is high or when you are engaging in some kind of strenuous exercise. Now the question is, why do we sweat there? It is the microorganisms (bacteria) on our skin that are to be blamed. Also, the associated foul odour is caused by bacteria on the skin coming into contact with sweat, water, salt, and so-called fat.

But were you aware that few people sweat an abnormally large amount? This condition is known as "axillary hyperhidrosis." 

💡 Did You Know?

Some persons with hyperhidrosis continue to sweat even when they are not hot or feeling strong emotions.

How Does Botox Work?

Though botox is most commonly associated with the reduction of wrinkles in cosmetic procedures. It is also an exceptionally effective treatment for hyperhidrosis.

💡 Did You Know?

Botox benefits typically last between 4 and 12 months, and in some cases up to 14 months.

Botox injections work by blocking the nerve signals that are responsible for sweating, thereby preventing the sweat glands from producing an excessive amount of sweat. However, these nerves can regenerate between four and six months after the initial therapy, so repeated sessions of the treatment are required. In most cases, it will take between two and four days before you notice any results, and it will take approximately two weeks for the injections to have their maximum impact.
