Summarize this article:

Although they can be expensive, Botox injections are an effective way to stop gustatory sweating. This treatment is done in your dermatologist's office. They will administer the Botox by injecting it directly into the affected areas on your face. The dose varies from person to person, but most people experience relief within a week of treatment. The effect of Botox injections only lasts 9 to 12 months. Because of this, you will need to go in for another treatment after 9 to 12 months. Most people tolerate the treatment well and experience no significant side effects. If your gustatory sweating is caused by nerve damage, reconstructive surgery can be used to repair those nerves. Because the procedure is complex and has a lot of potential complications, finding an expert surgeon can be very difficult. However, it may be worth a try if the other therapies prove to be ineffective at stopping your gustatory sweating. Investigational therapies are treatments that are still being tested for effectiveness. You can find current information on clinical trials in the U.S. for gustatory sweating by visiting https://www.clinicaltrials.gov. The National Institute of Health (NIH) Clinical Center also conducts clinical trials on gustatory sweating.
