Abstract: A lash adhesive liner formulation includes a pressure-sensitive adhesive and between about 0.02 and about 0.3 weight percent glycerin, where the pressure-sensitive adhesive is activated by pressing a lash band of a lash against the pressure-sensitive adhesive that has been applied to the eyelid. The lash is secured near a lashline of an eyelid by applying a layer of lash adhesive liner formulation to the eyelid, allowing the lash adhesive liner formulation that has been applied to the eyelid to dry for 5-15 seconds so that the lash adhesive liner formulation becomes tacky, and then pressing the lash band of the lash firmly against the tacky lash adhesive liner. The lash adhesive liner formulation may include a colorant, such that the formulation may also substitute for an eyeliner.
