Botox has become so popular that it not necessary to the use to be this wonderful utility for the correction of the signs of aging. The name comes from "Botulinum Toxina" which in its normal concentration is a poison, but that was used for the last 25 years in neurology at a dose of up to 200 times less than the normal concentration in non-invasive aesthetic surgery and aesthetic medicine.
Botulinum toxin brings on muscular paralysis, the transmission of nerve impulses to the neuromuscular junctions within a structure block known as a synapse. This localized paralysis is distributed in the body and nervous system forms new nerve rungs in a few months. This means that the effects of botulinum toxin are temporary.
The main applications are the paralysis, or rather the relaxation of certain facial muscles used when gesturing, such as for example of forehead muscle the forehead to wrinkles, if contracts, which the Roundhead muscle, produced the Crow's feet, the WPA and procerus muscle, the muscle folds create it in the glabella, or the distance between the eyebrows.
There are other applications, to relax the paralysis of the muscles of the micro fiber and to improve the wrinkles on the upper and lower lips (commonly referred to as bar-code lines), and also the Platysma bands (cable, that is displayed, if the neck muscles remain contract and the progression of age).
It is important to know that this botulinum toxin has its achievements, its failures and its limits. It has achieved good results for a limited period of time, but after a certain age, transfer to surgery, to correct the loss of elasticity of the skin is often necessary as next.
It is true, though, that it relaxes the muscles of gestural expression of the upper part of the face it is also true that the face is looking smooth, but without moving. Also, depending on the injection technique is employed, you can trigger the tail of the eyebrows, but the lift not controlled 100% and should be done by an experienced specialist.
Also, when the botulinum toxin is injected too close to the eyes, it can completely prevent the eyebrows is raised, is the sensation of heavy and drooping eyes. The reason for this feeling is that in the course of our lives, the upper eyelid has more skin and heavier. To open throw your eyes your eyebrows, which causes that wrinkles on the forehead and leaves the eyes look rounder.
Another limitation is the gradual emergence of wrinkles above and below the injection points of the Crow's feet. To understand this problem, you must understand that the ball muscle of the eye, which is responsible for the Crow's feet, which one to three centimeters in diameter has the form of a few round glasses. Which means that if you repeatedly paralyze a limited section this muscle, new wrinkles to and up and down the paralysed area appear.
When this happens, it's time to think about another method of correction, and specifically how aesthetic surgery can help. before 25 years botulinum-toxin was originally used to correct squint, blocking of the muscle control the eyes, and the last 10 years, it has been in the field of aesthetics. It is not known, cause serious problems.
