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.

As a result, if you have small crow’s feet around the eyes but more severe forehead wrinkles, you may see results sooner in the relaxation of the crow’s feet. However, since individual results may vary, your doctor may not be able to guarantee which area of the face will react to the Botox injections first.

A: Often to get a long lasting effect with Botox, a practitioner will mix it while you are there and immediately administer the drug. This can allow the effects of the Botox to last as long as 6 to 8 months. However, one down side is that it can take 2 to 3 weeks to notice initial results. Once the Botox sits around for more than just a few hours it has less long term effects. Spa treatments with Botox which usually is the much cheaper Botox B, usually only lasts 2 to 3 months. However, onset or action of the drug occurs usually within a week. The bottom line is you should wait about one more week.
