People who want to combine winged eyeliner and false-lash application into a single step rather than applying liner and lash glue separately. It suits anyone applying strip, individual cluster, or magnetic false lashes at home or professionally, and is best suited to users comfortable with a liquid-liner-style brush application rather than a standard glue-and-tweezers routine.

Its advantage over a standard lash adhesive is that it removes a whole step from a lash look: instead of lining the eyes and then separately gluing on lashes, the black liner itself is the bonding agent, so the lash line, lash band, and eyeliner become one continuous black edge.

Apply two thin layers of the black formula along the upper lash line using the fine-tip brush.

While the liner is still slightly wet, position the false lash strip, cluster, or magnetic lash against the lash line and press gently to secure.

To remove, gently lift the lash band from the outer corner, then use an oil-based eye makeup remover to clear any remaining adhesive/liner residue.

Pros

• Eliminates a separate eyeliner step, since the same product lines the lash line and bonds the false lash
• Fine-tip brush allows more precise placement than a typical glue applicator, useful for winged-liner looks
• Compatible with strip, individual cluster, and magnetic lash styles

Cons

• Because the adhesive doubles as visible liner, any unevenness in the line is more noticeable than with a glue applied to the lash band itself
• The false lash has to be pressed into the liner while it's still slightly wet, giving a narrower working window than a two-step glue-then-place method
• Being a waterproof formula, full removal needs an oil-based eye makeup remover rather than rinsing with water
