Aesthetic facial treatments are also performed by dentists, who are excellent experts in head and neck anatomy (muscles and nerves).
Botulinum toxin is a neurotoxic protein produced by the bacterium clostridium botulinum and is injected into the muscle in order to block the transmission of the signal coming from the nerve, temporarily relaxing the corresponding muscle and consequently fading or disappearing wrinkles. The procedure takes a few minutes and the result is visible after the third day of injection. The effects of Botox are stable for about 4-6 months after treatment, depending on the area where it is injected.
