Botox is a trade name for botulinum toxin A. Basically, the botulinum toxins block the nerve signals that instruct your muscles to contract. So why would anyone want to purposely inject such a dangerous substance into their body? The answer is simple: if a muscle is paralyzed, it cannot move; if it cannot move, it cannot wrinkle. Thus, Botox works by freezing the muscles that cause wrinkles. In addition to cosmetic reasons, Botox has also been sought out to treat chronic migraines and even TMJ symptoms. There are advantages and disadvantages to all treatments, and Botox definitely has its pros and cons, but is it the right solution for you?
