BOTOX® Cosmetic is a prescription drug that, when injected, temporarily paralyzes muscles. It contains a purified and safe form of botulinum toxin A, which is produced by the microbe that causes botulism. Manufactured by Allergan, Inc., it is used to treat permanent furrows and deep wrinkles in the skin that are formed by the continual contraction of facial muscles.
Using a fine needle, BOTOX is injected directly into the facial muscles that are causing furrows and lines. Results can usually be seen within 3-7 days and typically last for 3-6 months, although areas that are treated on a regular basis may retain results longer.
