What muscles cause a frown?
The muscle in the eyebrow consists of a single muscle called Procerus and Corregator muscles.
Both muscles originate on the bone and pass upwards attached to the skin.
The Procerus passes vertically and when it contracts it gives you a single crossline on the top of the bridge of your nose.
The Corregator passes upwards and outwards from the bone to the skin and when this contracts it gives you either a vertical or slightly slanted frown line coming up from the inner aspect of the eyebrow.
The strength and exact location of this lines varies between individuals and therefore the botox treatment, the areas should vary aswell.
Everyone’s muscles are different and the location of the injections should also be different.
Your practitioner will get to know your face and the characteristics of your muscles and should be able to tailor individual treatment for you.
