Underarm Botox, a Proven Method to Reduce Sweating
Sweating is normal. In fact, it’s essential: Humans need to sweat in order to regulate body temperature.
But some people sweat much more than is needed. Hyperhidrosis, more commonly known as excessive sweating, can significantly affect a person’s quality of life. In some cases, problematic sweating is limited to one area of the body, such as the underarms or feet, a condition called focal hyperhidrosis. Other cases are more generalized, with sweating over large areas of the body. The most common areas affected by hyperhidrosis are the scalp, underarms, hands, feet and groin area.
Excessive sweating can significantly affect a person’s life,it can be embarrassing and socially isolating, and many people find the condition quite upsetting.
often associated with cosmetic wrinkle reduction—is also a particularly effective treatment for focal hyperhidrosis. Botox injections use botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. The United States Food and Drug Administration (FDA) have also approved Botox injections to treat excessive underarm sweating. It works by blocking a chemical in the body that activates the sweat glands.
According to the International Hyperhidrosis Society, underarm Botox injections can reduce underarm sweating by 82–87%. The effects can typically last 4–12 months, or up to 14 months in some cases.
People who receive underarm Botox injections tend to see results 2–4 days after treatment. The full effects are usually noticeable within 2 weeks.
However, Botox is not a permanent solution for excessive underarm sweating. A single treatment lasts around 4–12 months, so a person needs ongoing injections. Retreatment is typically needed in four to six months, as the nerves regenerate. Over time, however, patients can go longer between treatments.
To date, the FDA have approved Botox injections for underarm use only. However, a doctor may prescribe the treatment for excessive sweating elsewhere on the body, such as the hands, feet, head, or face.
How does it work?
Botulinum toxin is a neurotoxin made by the bacteria Clostridium botulinum. Neurotoxins are substances that affect the structure or function of the nervous system.
Botox alters the function of certain neurotransmitters. These are chemicals in the body that instruct the body to react in a certain way. Botox blocks the neurotransmitter that tells the sweat glands to activate, to control sweating in the injection area.
