They are wrinkles that are formed around the corner of the eyes in a pattern that resembles crow’s feet.
They are formed due to loss of skin elasticity with age, weakening of facial muscles, and repeated laughing or squinting.
Careful injection of Botox into the region around the corners of the eyes prevents the muscles in this area from contracting vigorously during squinting or laughing. This eliminates the crow’s feet effect during facial expression.
