Ellacor treatment area - why is it performed on the lower third of the face rather than higher on the cheeks?

I am curious about the healing process for Ellacor and specifically if there is a reason it is performed on the lower 3rd of the face, rather than higher on the cheeks. Wouldn't higher on the cheek allow for less pull down on the ocular and cheek area, and allow for a higher lift for the lower sections as it heals? Is there a higher risk of complications in the cheek area? Thank you!
