Natural eyelashes often lack sufficient lift or structural retention over time. Addressing this physical limitation allows for long-term aesthetic modification without invasive procedures.

Difficulty in achieving precise alignment and secure attachment of synthetic fibers to the eyelid. Reducing placement errors improves cosmetic symmetry and user safety.

Non-uniform application and poor characterization of individual eyelashes lead to suboptimal cosmetic results. Precise mapping and application overcome physical variances in fiber geometry.
