Botox has been used by ophthalmologists and neurologists since 1989 to treat lazy eye, eye spasms and other neurologic disorders.  Since 2002, Botox Cosmetic has become a popular, non-invasive cosmetic procedure to diminish and/or eliminate wrinkles that are caused by repetitive muscle movement.  Injecting Botox into the muscle causes temporary weakness or paralysis of the muscle and can diminish or eliminate fine lines and wrinkles that occur with expression.  

 

The FDA has approved Botox Cosmetic to minimize the vertical lines between the eyebrows. and "crow's feet" (wrinkles around the eyes).  Although not FDA approved, Botox Cosmetic has been used for many years for treating other areas/wrinkles of the face such as the horizontal forehead lines, dimpled chin, "bunny nose" and neck bands.  Many individuals are concerned that Botox will result in a "frozen" look, but a natural look can be achieved when injecting the correct amount by a qualified medical professional.  Results are noticeable in 3 to 4 days, but the full effect may not be seen for 2-4 weeks.  The effects last 3 to 4 months.  However, the duration of response is dependent upon the injection site and dose.  Some individuals, particularly those who have repeated injections in the same area, may experience benefits for six months or longer.  Men typically require higher doses of Botox than women.  The amount of Botox needed to minimize or eliminate wrinkles can vary signifiantly among individuals, but here is a general guideline for Botox dosing by area:

 

-   Forehead (horizontal lines) 6-20 units

-   Frown lines (vertical lines between the eyebrows) 12-24 units

-  "Crow's feet" 4-12 units/side

-  "Bunny nose" 4-6 units

-   Dimpled Chin  4-6 units

-   Neck bands 8-12 units/band
