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.
How does it work?
Botox is a neurotoxin. These substances target the nervous system, disrupting the nerve signaling processes that stimulate muscle contraction. This is how the drug causes temporary muscle paralysis.
In order for any muscle to contract, the nerves release a chemical messenger called acetylcholine at the junction where nerve endings meet muscle cells. Acetylcholine attaches to receptors on the muscle cells and causes the cells to contract, or shorten.
Botox injections prevent the release of acetylcholine, which stops the muscle cells from contracting. In this way, the toxin helps the muscles to become less stiff.In this article, we explain how Botox works and explore its uses, side effects, and other risks.
