The procerus muscle is the pyramid-shaped muscle extending from the lower part of the nasal bone to the middle area in the forehead between the eyebrows where it is attached to the frontalis muscle. Its location allows it to pull the skin between the eyebrows down. It is associated with transverse lines and it is usually the site targeted during treatment or correction of wrinkles. Researchers in the field of plastic surgery who are looking into possible remedies for transverse wrinkles and glabellar frown lines study the structure and function of procerus muscles. They use specimens that are taken from the buccal branch of the superior orbital nerve. Overactivity of the procerus muscle and corrugator supercilii results in the appearance of wrinkles. This can be corrected with the injection of botulinum, a toxin (commonly known as the Botox procedure) in the said sites. Marked improvements are reported after Botox. This approach to correcting wrinkles has also helped individuals suffering from thyroid orbitopathy.
