Botox® and fillers are two types of injectables, which are both injected with a needle. The biggest difference between Botox® and fillers is that Botox® is used to reduce fine lines and wrinkles by paralyzing the underlying muscles, fillers on the other hand will fill in wrinkles.
Botox injections are shots that use a toxin to prevent a muscle from moving for a limited time. These shots are often used to smooth wrinkles on the face. They're also used to treat neck spasms, sweating, overactive bladder, lazy eye and other conditions.
