Elleebana Original Lash Lift Glue is a dermatologically tested, water-soluble synthetic polymer with excellent film-forming and bonding strength for the One Shot lash lift system. Its flexible, high-tensile formula holds securely through processing without compromising lash health. Store upright in a cool, dry space with the lid sealed tight; buildup around the seal lets in air and shortens shelf life. Good for use up to 3 months after opening, even with slight color change. Unopened shelf life is 12 months. Never return a client-contacted brush to the bottle.
