Dear Olgaelle, Thank you for your clinical post. Crow’s Feet are the horizontal lines at the sides of the eyes are caused by excessive animation of the underlying muscle called the orbicularis oculi. Generally, the best treatment for excessive animated and resting Crow’s Feet is the use of Botox. Botox is a protein injected into the muscle that causes the overlying wrinkle and use of Botox in the orbicularis oculi lateral fibres will soften dynamic and resting Crow’s Feet. When resting Crow’s Feet are still apparent after Botox and the use of fractional laser resurfacing such as Fractional CO2 or fractional radio frequency resurfacing such as the Fractora are an excellent second option often using conjunction with Botox. The use of soft tissue fillers for the treatment of Crow’s Feet is unusual, but can occur. When fractional resurfacing and Botox is not enough sometimes a diffuse fine injectable in the subdermal plane with the use of dilute Volift or Sculptra can be helpful in treating Crow’s Feet. By following this algorithm and sequential treatment generally Crow’s Feet patients can be very happy. I hope this information has been of some assistance and best of luck.
