Experiments with the use of drugs for medical purposes on the basis of botulinum toxin began in the US in the 70s of the last century. However, the use of Botox for cosmetic purposes was approved only in 2002. The drug is immediately won wide popularity. Today in America, for example, Botox injections - is common, they are made at lunchtime. In Russia, in addition to Botox used another means on the basis of botulinum toxin - Dysport.
I must say that to defeat age wrinkles, these injections are not capable, they eliminate a mimic. The effect of the injection is stored for 3-4 months, so they have to be repeated regularly. How does botulinum toxin? He breaks the transmission of nerve impulses to the muscles of the face, located at the injection site. Pulse with a nerve ending to the muscle does not reach, so she is paralyzed. As a result, wrinkles are smoothed, but after a while everything returns to normal, the muscle again begins to shrink, wrinkle back in place.
Do not afraid to prick the skin in such a serious poison? On the one hand, the dose is negligibly small. On the other - it can still spread beyond the position of the region, although the probability of such an outcome is very small. There were times when, for example, after the injection of botulinum toxin into the glabella hit the area of the upper eyelid. As a result, his eyes were half closed. Sometimes after injections of Botox or Dysport lowered corners of her mouth, increased salivation opens. Sometimes a complication becomes asymmetry of facial muscles or difficulty swallowing due to partial paralysis of the larynx.
To prevent the occurrence of such unpleasant consequences, the manufacturer recommends cosmetologists inject the drug slowly, in small portions, and see the reaction of the body of the client. So the choice of a professional for these injections is very important.
If you do decide to take a note. That after the injections can greatly head ache. But there are cases where people have made the Botox were completely tormented them before headaches. Why is this happening, scientists have not yet established, studies are still underway. So botulinum toxin - a phenomenon not fully understood. Keep this in mind in deciding on the procedure. Although most experts still agree that with all the doctor's recommendations and correct, professional administration, the risk is minimal trouble. And can end in tears, even these procedures. Like liposuction, mesotherapy or phenol peels. So decide for yourself how to keep youth.
