Ardell DUO Eyelash Adhesive works beautifully with ardell eyelashes. DUO blends with lashes when it dries, and keeps lashes securely in place until you remove them. DUO is waterproof and it dries quickly and invisibly. Ardell's LashTite Adhesive is a longer lasting adhesive and is used on individual eyelashes only. It can hold eyelashes for weeks but must be removed with LashFree Remover if it becomes necessary to remove the eyelashes.
