What is botulinum toxin?
Botox® is the most common name used for botulinum toxin. This toxin is produced naturally by the bacterium Clostridium botulinum and has the property of inhibiting nerve transmission in muscles, thus preventing their contraction.
When injected into the face, botulinum toxin affects the nerves that control the muscles, preventing them from contracting, giving a much smoother and relaxed appearance to the face.
Botulinum toxin injections has been used since 1975 to correct infantile strabismus, facial tics and uncontrollable blinking (blepharospasm), spasmodic torticollis, dysphonia, temporomandibular joint pain and, of course, to reduce facial wrinkles in aesthetic medicine.
What are the main uses for facial Btx?
botulinum toxin injections is mainly used to correct expression lines in the upper part of the face: frown lines, crow's feet, horizontal forehead lines, etc.
Botulinum toxin injections are also performed to correct the appearance of the neck, lips and the corners of the mouth, where the "smile lines", also known as "sadness lines" or "bitterness creases", are sometimes found.
The use of Btx on the face is considered an aesthetic treatment and can be seen as a corrective or preventive measure, as soon as the first wrinkles or expression lines appear.
