Botox
Botox is a purified protein that temporarily blocks muscle activity leading to less lines and wrinkles on the face. Frown lines between the eyes are the most common area for Botox injections. Other areas include forehead lines and the lines around the eyes known as “crow’s feet.” In general, Botox is used for wrinkles in the upper one third of the face, whereas fillers are used for the lower two thirds of the face with some exceptions. In all of these areas, the wrinkles are present due to the action of small, thin muscles of facial expression. Overtime, the muscles effectively “stretch” the skin leading to lines. Botox is safe for most patients, but it is important to review any history of muscle or nerve abnormality with your physician.
