Botox? is used to improve the look of mild to severe frown lines for a short time.

Botox? comes from a kind of bacteria. The bacteria can make you very sick. But doctors have found that the chemical in Botox? can also help treat some health problems. They have been using it safely for many years.

Some wrinkles are caused when a muscle contracts (tightens up). Botox? is injected through the skin into the muscle with a needle. The Botox? keeps the muscle from contracting. When the muscle can't contract, the wrinkle doesn't show as much.
