Based on its formula, is this eyeliner safe for sensitive or irritation-prone eyes?

The product contains potential irritants such as phenoxyethanol, methylparaben, propylparaben, and nano-sized CI 77266 pigment, so users with sensitive eyes should perform a patch test before regular use, though the formula complies with standard cosmetic safety regulations.

What is the role and benefit of CI 77266 (nano iron oxide) in this eyeliner?

CI 77266 provides a deep black shade and enhances the wear time by delivering a highly concentrated, light-fast pigment, but its nano-particle form may raise safety concerns for ocular exposure.

What is the recommended application frequency for this eyeliner, and does it contain any controversial ingredients?

It is intended for daily use and typically remains intact for several hours without reapplication, and it does contain preservatives phenoxyethanol, methylparaben, propylparaben, as well as the nano pigment, which are sometimes debated in the cosmetics community.
