Botulinum toxin, better known as "Botox", is a powerful medication that prevents the release of acetylcholine, the neurotransmitter responsible for muscle contraction. Its application causes the relaxation of the muscles involved in facial expression, softening or eliminating the appearance of dynamic wrinkles. This relaxation property allows this medication to relax the muscles related to bruxism and the gummy smile.

​

The "Botox" is also very effective to treat patients suffering from hyperhidrosis (excessive sweating). This medicine manages to inhibit the secretion of the sweat glands by reducing excessive sweating in areas such as the armpits, soles of the feet and palms of the hands.
