The Botox Procedure
Botox injections are performed without anesthesia because they are virtually painless. Only a very small sting is felt when the injections are made. The effects are not permanent and may need to be repeated two to three times per year to retain the effects. Research has suggested, however, that long term use of the injections leads to a longer duration of each treatment's effect. Patients over the age of 65 may not experience such dramatic results. Botox is only useful in treating expression lines and cannot be used to repair sagging skin caused by aging.
