Facial marks and wrinkles can be treated with neurological procedures

BOTOX � was used primarily in the United States in 1989 to treat strabismus.

Since the early 90s, the botulinum toxin has been used to treat neurological disorders such as involuntary movements, spasticity, tension headache, migraine and hyperhidrosis, these procedures adopted by the clinic since 1998. But since 1993 the clinic had treated patients by Dr Elizabeth Quagliato, in Campinas.

Later the toxin had been used for aesthetic purposes, leafing speech marks that appears on the face, in the form of wrinkles and grooves, which are in their neurological root of origin, caused by the action of muscles of expression that are below the skin that area, which made many times, staying with hypertrophied and tone increased.

Sold under trade names of Botox or Dysport, the drug blocks the functioning of the muscle where it was injected, which make them relax and not contract for some time. The muscles in which they have no light is injected into the body thus causing the wrinkles. The relaxation of muscles is needed in order to get the disappearance of wrinkles.

By selectively interfering with the ability of contraction of the muscles, the lines of expression are softened and, in many cases, are virtually invisible in a week.

The product operates between the nerves and muscles of the face as a neuroparalisator, ie, blocks the nerve transmission to the muscles, inhibiting the release of acetylcholine - a chemical that causes muscle contractions without muscular influence in motility.

The movement may return in a period of time that varies from patient to patient, but the wrinkles can come back in about 6 months or more. The BOTOX � should be reapplied, not when the movement immediately return, but a little later, when the wrinkles begin to reappear.
