According to Glamour, approximately 15.3 million Americans struggle with hyperhidrosis. This is a medical condition that causes the body to sweat excessively, causing aesthetic and daily life problems.
When measures such as wearing breathable clothes, increasing the number of baths and body hygiene, using deodorant powders or waxes… do not help with excessive sweating, Botox to treat underarm sweat will help. useful.
Although best known as a wrinkle prevention treatment, Botox is also approved by the FDA (US Food and Drug Administration) to help prevent hyperhidrosis. In addition, Botox is also used to treat the face, hands and feet.
Cosmetic dermatologist Dr. Michele Green explains that those are the areas where sweat glands are most concentrated. “Eccrine sweat glands exist throughout our body but are concentrated in areas such as the feet, palms and armpits. When the body feels too hot, or when you are exerting yourself, the nerves The nerves activate sweat glands to produce sweat for the purpose of cooling the body. Some people sweat more than others because the nerves overreact.
“Botox is injected directly into the sweat glands to block the release of acetylcholine: a neurotransmitter that is transmitted to the sweat glands to produce sweat. This helps reduce sweating in targeted body areas.” , said Dr. Michele Green.

According to Dr. Smita R. Ramanadham, Botox is one of the most commonly used neuromodulators to reduce wrinkle formation.
When inserted into the muscle underneath the skin, botox blocks acetylcholine from being released from the nerve and essentially disrupts its communication with the muscle, weakening the muscle and thus reducing wrinkles in the skin. Botox is used to treat horizontal forehead wrinkles, excessive sweating, migraines, crow’s feet, etc.
Hyperhidrosis is caused by overactive sweat glands, leading to excessive sweating for no particular reason, even when you are in a cool area, not moving and not nervous or stressed. straight. There are two types of primary and secondary hyperhidrosis.
Primary hyperhidrosis is a phenomenon in which a certain part of the body such as hands, armpits, feet… sweats excessively without any underlying medical cause. While secondary hyperhidrosis occurs throughout the body and is due to an underlying medical problem.

How does Botox reduce sweating?
Botox treats sweat the same way it prevents wrinkles, says Dr. Ramanadham. Once injected and begins to work, it will block communication between nerves and sweat glands, thereby effectively reducing the gland’s sweat secretion.
Some people learn to adapt, but others struggle with excessive sweating because it causes social anxiety, stains clothes and causes discomfort.
Using Botox to treat hyperhidrosis in the armpit area was approved by the FDA in 2004. Although the agency has not approved the use of Botox on the arms or legs, some experienced dermatologists have used it. and found them effective in reducing sweating on the hands, feet and face. The effects of Botox on the arms and legs usually do not last as long as on the armpits.
Botox can work quickly just a few days after injection. Usually 4-6 days, full effect comes about 2 weeks after injection. The effect can last for at least 3 months, 1 year or depending on the body’s rate of Botox metabolism and the injection site. Normally patients will repeat injections every 6 months. The effects of Botox on the arms and legs usually do not last as long as on the armpits.
