BOTOX is an injectable remedy for wrinkles, but is not a dermal filler like JUVÉDERM® or a collagen stimulator like Sculptra® Aesthetic. Instead, BOTOX uses an active ingredient called botulinum toxin type A to temporarily relax the muscles in the face that cause wrinkles exacerbated by facial movement.
