The Hyperhydrosis is the excessive production of sweat. It is the normal response to an increase of the body temperature (heat, exercise, fever) and emotion like stress.
Botox has been used to prevent underarm hyperhydrosis by blocking the end of the eccrine sweat* gland nerves (responsible for discharging sweat directly to the surface of the skin), preventing their function and thus the production of sweat.
Botox is considered a safe option because it is administered in low, purified concentrations. In addition, it has been used for more than 20 years in aesthetic medicine, and more than 30 years in therapeutic medicine.
The substance disappears gradually from the body without the risk of adverse reactions.
