Botox is a protein made from Botulinum toxin, which the bacterium Clostridium botulinum produces. This is the same toxin that causes botulism. Botox is a toxin, but when doctors use it correctly and in small doses, it can have benefits. It has both cosmetic and medical uses. As a cosmetic treatment, Botox injections can reduce the appearance of skin wrinkles. Also, the Food and Drug Administration (FDA) have approved it as a treatment for various health issues, including eyelid spasms, excessive sweating, some bladder disorders, and migraine.
