Make lash application simpler for your guests with a true multitasker. DUO Line It Lash It works as adhesive when wet and eyeliner when dry, allowing you to define the eye and secure lashes in one step. If a client can apply liner, she can apply her lashes — making this an easy retail add-on that builds confidence at home.

This 2-in-1 formula replaces the need for separate glue and liner. Simply glide it along the lash line, apply the strip lash, and it holds comfortably in place. It pairs seamlessly with Ardell lashes, giving guests a clean, defined base with reliable wear.

The lightweight, long-lasting waterproof formula helps keep lashes secure through heat and humidity without feeling sticky or heavy. Clients get the bold lash look they love with comfort that lasts throughout the day.

Designed with a fine-tip applicator brush, it creates a precise, richly pigmented black line while providing a smooth surface for lash placement. The controlled application makes it approachable for beginners and efficient for professionals.

Developed from one of the world’s best-selling lash adhesive brands, this medical-grade formula is cruelty-free, paraben-free, and sulfate-free — offering peace of mind along with performance.
