Allergan Botox is a purified neurotoxin (onabotulinumtoxinA) approved by the FDA for the temporary reduction of moderate to severe dynamic wrinkles. It works by blocking nerve signals to targeted facial muscles, reducing muscle activity and smoothing expression lines, particularly in the glabellar, forehead, and crow’s feet areas.

Botox® Cosmetic by Allergan is a purified protein derived from botulinum toxin type A. It works by temporarily relaxing the muscles that cause dynamic wrinkles—those formed from repetitive facial expressions like frowning, squinting, or raising your eyebrows.
