DUO® Eyelash Adhesive is the world's best-selling lash adhesive and has been a favorite of professional makeup artists for decades. This latex-free long lasting formula is intended to keep individual lashes on for 2-4 weeks. USAGE: Pour 2-3 drops of adhesive onto a small piece of foil, and then gently grasp a single lash with tweezers near the knotted end pulling from the tray. Next dip knotted end of lash into adhesive and place lash on top of your natural lash with the knotted end as close to your eyelid as possible. CAUTION: Use only as directed. Keep away from children. Avoid getting into eyes. If contact occurs, wash immediately with lukewarm water. Try using Qosmedix professional lash applicators to apply lashes. *This lash glue is not intended for temporary or full set lashes.
