Botox blocks signals from the nerves to the muscles. The injected muscle can no longer contract, which causes the wrinkles to relax and soften.
It is most often used on forehead lines, crow's feet (lines around the eye) and frown lines. Wrinkles caused by sun damage and gravity will not respond to Botox.
The procedure takes only a few minutes and no anesthesia is required. Botox is injected with a fine needle into specific muscles with only minor discomfort. It generally takes three to seven days to take full effect and it is best to avoid alcohol at least one week prior to treatment. Aspirin and anti-inflammatory medications should be stopped two weeks before treatment as well in order to reduce bruising.
