Using a very fine needle, BOTOX Cosmetic is injected directly into facial muscles that are causing furrows and lines.

Receiving the injections requires no anesthetic, but some doctors choose to numb the area to be injected with ice packs or a topical anesthetic cream.

Results can usually be seen within a few days of treatment, and typically last up to four months, although areas that are treated on a regular basis may retain results longer. Injections should be given only by qualified medical professionals.
