It's the eye position and craniofacial skeletal anatomy

Very conservative eyelid surgery
It's important at a young age not to overdo the eyelids, so a very conservative upper blepharoplasty can remove some of the hooding affect on the upper lids. Do not expect them to open up your eyes, and a canthoplasty is not needed. Eyelid surgery can be accomplished at the same time as a chin implant and a rhinoplasty procedure. For many before and after results of all three procedures, please see the link and the video below
