What are buckyballs used for in mascara?

Buckyballs, or fullerene molecules, are used in some mascaras for their unique properties, including their ability to enhance the thickness and volume of eyelashes. Their spherical shape allows them to coat individual lashes evenly, providing a fuller appearance while also being lightweight. Additionally, they may offer benefits like improved adhesion and potential antioxidant properties, contributing to healthier lashes over time.
