Botox has become so popular that it is not necessary to insist on using this wonderful tool for correcting the signs of aging. Its name comes from “botulinum toxina” which in its normal concentration is a poison, but which has been used for the past 25 years in neurology at a dosage of up to 200 times less than its normal concentration in non-invasive aesthetic surgery and aesthetic medicine.
Botulinum toxin brings about muscular paralysis , blocking the transmission of nerve impulses to the neuromuscular junctions inside a structure known as a synapse. This localised

It is important to know that botulinum toxin has its successes, its failures and its limitations. It has great results for a limited period of time, but after reaching a certain age, passing on to surgery to correct the loss of elasticity in the skin is often the necessary next step.
While it is true that it relaxes the muscles of gestural expression of the upper part of the face, it is also true that the face is left looking smoother, but without being able to move. Furthermore, depending on which injection technique is employed, you can raise the tail of the eyebrows, but the lift cannot be controlled 100% and should be done by an experienced specialist.
Also, if the botulinum toxin is injected too close to the eyes, it can completely prevent the eyebrows being raised, giving the sensation of heavy and drooping eyes. The reason for this sensation is that during the course of our life, the upper eyelid has more skin and is heavier. Consequently, to open your eyes raise your eyebrows, which causes wrinkles on the forehead and makes the eyes look rounder.
Another limitation is the gradual appearance of wrinkles above and below the injection points of the crow’s feet. To understand this problem, you have to understand that the orbicular muscle of the eye, which is responsible for the crow’s feet, has the shape of a pair of round glasses from one to three centimetres in diameter. Meaning that if you repeatedly paralyse a limited section of this muscle, new wrinkles will gradually appear above and below the paralysed area.
When this happens, it is time to start thinking about a different method of correction, and specifically how aesthetic surgery can help. 25 years ago, botulinum toxin was originally used to correct squinting, blocking the muscle controlling the eyes, and for the past 10 years, it has been used in the field of aesthetics. It has not been known to cause any serious problems.
