The chemical that use in Botox is made by a bacterium known as Clostridium botulinum. This bacterium lives naturally in the soil and bodies of water. It also found in shellfish. The bacteria is usually harmless, but when it multiplies, it produces a toxin called botulinum. When used for wrinkles of the skin, it blocks nerves that control the contraction of muscles. The injected botulinum toxin causes the muscle to relax, thereby softening the wrinkle. The injections are safe and minimally invasive.
This protein, first identified in 1895, inhibits the release of acetylcholine at the neuromuscular junction. When superifically injected into the targeted muscle groups, the inhibited muscles then aids in smoothing out fine lines and wrinkles in the areas of treatment.
