Our forehead is the said to be the part that is most likely to
form wrinkles. Forehead wrinkles are
therefore one of the major targets of many anti-wrinkle treatments. There is
only one major reason being considered why forehead wrinkles are very common to
occur. And that is because of our repetitive facial expressions.
As mentioned in Wikipedia.com, our forehead is composed of three muscles
and these are the Occipitofrontalis, Procerus and Corrugator supercilii. All of these muscles are being controlled by
what they call the facial nerves, thus, they are the muscles responsible in
creating different facial expressions such as raising of eyebrows, frowning,
squinting, and the like.
