Botox injections treatment is the most popular cosmetic surgery as more than 6 million people chooses to undergo this treatment in a year. Botox is actually a neurotoxin which is derived from an organism named Clostridium botulinum and is non-toxic. Botox for wrinkles is an effective means of getting rid of various aesthetic problems as the injection can work by paralysing the muscle underneath the affected area. The botox injections treatment is also useful in the cure of excessive sweating, muscular disorders, headaches as well as certain types of bowel and bladder disorders. Though botulinum toxin is one of those few most poisonous substances present on the planet, it has proven to be a successful therapeutic protein when the frequency and dosage are kept under the required level. When your dermatologist injects the botulinum toxin in extremely small amounts, it works by stopping the signals to connect from the nerve endings to the muscles. It leaves the muscle unable to contract thereby paralysing them. In order to get your muscles get contracted, the nerves give out a chemical messenger or a neurotransmitter called acetylcholine at the point in which the nerve endings come in contact with the muscle cells. The acetylcholine gets attached to the receptors present on the muscle cells making the muscle cells to contract and shorten. The botox injections treatment stops the acetylcholine from being released and thus prevents the formation of fine lines and wrinkles. But before undergoing the treatment, you should know whether you have botox allergy and the botox side effects.
