Laughter lines are caused by the contraction of the orbicularis oculi muscle, a sphincter like muscle around the eye. In some cases these lines can be extensive, eventually causing permanent lines running across the temple and down towards the cheek. This is especially common in men.
Treatment with botox will not prevent smile or laughter expression of the eyes, but it will relax the orbicularis oculi enough to prevent permanent lines. Another reason for botox in this area is to open the eyes. Individuals who work outdoors without sunglasses, or on computers for long periods may find they ‘scrunch’ or ‘peak’ at the screen.
This is a beneficial treatment to give the eye area a relaxed and rejuvenated appearance.
