Botox is an injectable product composed of purified botulinum toxin. It is the most well-known injectable in a category referred to as “neuromodulators,” which also includes similar products like Dysport.
Botox works by temporarily disrupting nerve signals to the muscles where it is injected, which means that patients can no longer make extreme facial expressions that cause dynamic wrinkles. These are the wrinkles that form when you squint, frown, or smile, such as crow’s feet, glabellar lines, or horizontal forehead lines.
With modern injection techniques, however, you can still freely express yourself and avoid the “frozen” look.
