What is Botox®?
Botox® relaxes wrinkles using botulinum toxin, a neurotoxin that interrupts the communication between the facial muscles and the nerves that make them contract. In the minute quantities used for aesthetic treatments, Botox® works very safely. It has many medical as well as cosmetic uses, including the treatment of hyperhidrosis (excessive sweating) and eyelid spasms.
How Does Botox® Work?
When we smile or frown, the nerves send signals to our facial muscles, telling them to contract. Botox® interferes with that signal, so the muscles do not get the message to contract. Instead, they remain relaxed, and the skin above them can become smooth and relaxed as well.
How Long Does Botox® Last?
Botox® stays active for three to four months after treatment. Many people schedule regular appointments to refresh their Botox® and keep themselves looking younger. It has even become a popular maintenance treatment among younger people who do not have severe lines or wrinkles but want to make sure they don’t develop them.
Where Can Botox® Be Used?
The most common places for Botox® are crow’s feet around the eyes, horizontal lines across the forehead, and the deep creases between the brows (glabellar lines). However, it also treats “bunny lines” formed by wrinkling the nose or a “gummy smile” that reveals more gums than you would like. It can also treat lines around the mouth and platysmal bands in the neck.
