Botox is derived from a bacterium, Clostridium Botulinum, which is a natural bacterium that can be found in soils, forests, and lakes. It is also found in the gills and organs of crabs and various other shellfish, and the intestines of fish and various mammals. 

The bacteria and their spores are practically harmless and problems only start to occur when the spores develop into vegetative cells which then increase in number. At some point, the bacteria begin to produce botulinum toxin and this is what is fatal. Scientists have calculated that just one gram of botulinum toxin could kill a million people, while a couple of kilograms could wipe out the entire population of the planet.

For a muscle to contract, it must receive a signal from nerve cells. Nerves release a chemical messenger called acetylcholine at the point where nerve cells meet muscle cells. Acetylcholine attaches to receptors on muscle cells causing muscles to contract. Botulinum toxin prevents nerve cells from releasing acetylcholine, which in turn means that the muscles will not contract.

When used to treat fine lines and wrinkles, it is applied to three main areas: the forehead, crow's feet, and the frown. It has the effect of preventing the muscles from contracting and relaxing them, thus reducing the appearance of lines and wrinkles. 

After the injection, which can take up to 20 minutes depending on the number of areas to be treated, it usually takes two or three days before results can begin to be seen, although the full effect may not be seen in up to two weeks. The treatment will last up to three months before it wears off and another application is required. 

Subsequent injections tend to gradually last longer, so fewer treatments will be required. Botox treatments for wrinkles and facial lines are currently used by more than six million people a year, most of them, but not all, women.
