Botox® injections: the miracle solution for excessive sweating
Written and reviewed by Dr Bernard Hayot, ophthalmologist, RPPS 10003926226.

Botox® action against perspiration
Contrary to popular belief, Botox® isn’t just for treating wrinkles– it is also the most effective treatment for hyperhidrosis. Given as micro-injections, it treats perspiration on the underarms, hands, feet and face.
Botox® is essentially composed of botulinum toxin. Botulinum toxin acts by paralysing muscles. Here it acts on sweating by directly blocking the nerve signal that normally stimulates the glands producing perspiration.
Results are felt within two days of the session and are optimal within a month: no more need for antiperspirant.
Several sessions are nonetheless required for a lasting result.
