Botox blocks nerve signals to muscles.  Its dermatological uses are for wrinkles above the nose, squint lines, deep forehead creases, and excessive sweating of the underarms.

• How fast does it work?   There is usually a lag of 3 to 7 days for the medication to take effect. There are no special aftercare instructions and one can immediately return to normal activities. Results usually last 3 to 4 months and then gradually fade.
• What are the risks?  There may be soreness after the injections; one side may respond more than the other; or may affect nearby, non-targeted muscles. Rare serious side effects can be associated with repeated injections.
• How much does it cost?  Billing is based on the number of units used. Forehead treatments require 35 units, up to 50 if “crow’s feet” are done as well. Cosmetic facial treatments are not covered by insurance plans.
