Natural eyelashes suffer from gravity-induced drooping and loss of curvature over time. Maintaining a stable, elevated lash geometry provides the primary technical advantage in cosmetic application.

Inconsistent delivery of solid or pasty cosmetic formulations leads to poor application control. Optimizing the interface between the applicator and the product block ensures uniform deposition and prevents product wastage.

Insufficient pickup and release of viscous cosmetic formulas onto keratinous fibers. Improving transfer efficiency ensures uniform coating and prevents application failure.

Standard applicator geometries fail to hold and transfer sufficient product volume to the lashes. Improving the loading capacity ensures uniform coating and prevents multiple re-dipping cycles.

Rigid applicator handles and fixed geometries prevent uniform distribution and precise dosing of viscous formulations. Improving flexibility and ergonomic response ensures consistent coverage across irregular surfaces.
