Botulinum Toxin Type A (Botox Cosmetic) is a protein complex produced by the bacterium Clostridium botulinum, which contains the same toxin that causes food poisoning.
When used in a medical setting as an injectable form of sterile, purified botulinum toxin, small doses block the release of a chemical called acetylcholine by nerve cells that signal muscle contraction. By selectively interfering with the underlying muscles' ability to contract, existing frown lines are smoothed out and, in most cases, are nearly invisible in a week.
The medication takes 48 to 72 hours to take effect and can be expected to last about 3 months, though individual results vary and additional injections may be necessary to get desired results.
Botox was first approved in 1989 to treat two eye muscle disorders - uncontrollable blinking (blepharospasm) and misaligned eyes (strabismus). In 2000, the toxin was approved to treat a neurological movement disorder that causes severe neck and shoulder contractions, known as cervical dystonia. As an unusual side effect of the eye disorder treatment, doctors observed that Botox softened the vertical frown (glabellar) lines between the eyebrows that tend to make people look tired, angry or displeased.
In early 2002, Allergan performed studies to show a decrease in these frown lines for up to 120 days which satisifed the FDA. The agency granted an indication for temporary improvement in the appearance of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity in adult patients < 65 years of age for Botox Cosmetic.
In 2004, Botox received an additional indication for the treatment of severe primary axillary hyperhidrosis (armpit sweating) that is inadequately managed with topical agents.
While these are the only FDA indicated uses of Botox, Botox has been used to treat "crow's feet" and other areas of wrinkling in the face. Though no controlled studies have shown the safety and efficacy of Botox when used in these applications, hundreds of applications have proven out the efficacy.

BOTOX® injections are a simple and non-surgical procedure whereby very low doses of a natural purified protein are placed into specific muscles, which relaxes the muscles and prevents contraction.
The actual mechanism of action is by blocking or reducing the release of a neurotransmitter called acetylcholine, which is required in order for the muscle to contract. Without acetylcholine, the muscle will not contract. If the muscle doesn't contract, then it won't be able to pull the attached, overylying skin into creases which would result on your face as wrinkles.
Botox softens lines or disappears them entirely
When facial muscles contract, frown lines and wrinkles are formed over time. Once BOTOX® Cosmetic is injected into the muscles of the face, repetitive contraction of the facial muscles is limited, causing the lines soften or disappear.

Botox Relaxes Muscles By Blocking Nerve Signals
Botox is a purified form of botulinum toxin – a protein that has the capacity to block the transmission of acetylcholine in nerve cells. When acetylcholine is blocked, the muscle does not get a signal to contract. This relaxes a dynamic muscle that would normally contract and fold the skin into a wrinkle. Once the contraction of the muscle ceases, the skin is able to smooth out and the wrinkle disappears. After the Botox wears off, the muscle will begin to contract again and the wrinkle will reappear. Please consult a board-certified dermatologist to have your wrinkles smoothed out with Botox.
Botox. Who would think that a substance that is responsible for food poisoning could also make us look more youthful!
Botox is a prescription drug and is made by the drug company Allergan. It works by temporarily blocking muscle activity by preventing the transmission between nerve endings and muscle fibers. In lay terms this means that when Botox is injected into your muscle the muscle will temporarily relax.
How Botox Works
Botox or botulinum works by blocking signals from the nerves to the muscles. The injected muscles can longer contract causing the wrinkles to relax. Botox is most often used on forehead lines, crow’s feet and frown lines.
How does Botox work
I would recommend that you visit with at board certified plastic surgeon or dermatologist in your area to discuss your treatment options so they can be tailored to your concerns and goals.
How Botox works
Over time, however, and with repeated injections, the lines and wrinkles will become less severe as the muscles are trained to relax.
