Facial fat pads exhibit distinct metabolic and compositional differences, such as varying beta-carotene levels.

“So for example even in the eyelid region when we're doing surgery on the face and we're we're doing surgery on the upper eyelid we will see that the fat pads have different colors. So the medial orbital fat pad is lighter substantially compared to the much yellowower and more orange lateral fat pad. And that color will be different than the buckle fat pad. And one of the differences, there's beta carotene differences in the fat pads.”
