Allergan is the company that makes Botox and they are by far the largest company in Orange County, Los Angeles based on Wall Street rankings. The company is worth about $20 billion based on their current market cap. Botox accounted for about 40% of their 2007 revenues.

But a new competing product to Botox, Reloxin, will probably be launched before the end of this year. It's a wrinkle remover that's chemically similar to Botox but developed by their competitors, Medicis Pharmaceutical Corp.
