It stands for Botulinum Toxoid. It was created originally to treat certain eye conditions, mainly crossed eyes. This results in smoother and younger looking skin around the injected areas.
Some physicians use it to minimize neck banding.
This use will give a younger looking skin to the face and neck without surgery. Within 24-72 hours the muscles will relax and the wrinkles and frown disappear. The frustrated, tired and angry look on the face will disappear and the patient will look younger with a smoother skin. The treatment has to be repeated as the wrinkles or frown will re- appear. With repeated injection the effects might stay longer.
