The Botulinum toxin is a purified substance that injected into areas such as the armpits or palms of the hands, prevents the onset of sweat. It acts by blocking the activity of the nerve endings that innervate the sweat glands, thus preventing them from producing sweat.
The application under the armpits is practically painless, using topical anesthesia. The treatment takes about 10/20 minutes, in which a small amount of botulinum toxin is injected into the affected area, spacing the punctures between 1 and 2 cm. Its effect lasts between 6 and 9 months.
