EyeSense liquid eyeliner must be shaken prior to application. After you have shaken EyeSense place a small amount of liquid color on to the fable brush. Prior to placing the product on your eye lid, be sure to lightly blow on the color on the brush of EyeSense . This aids in the evaporation of the liquid ingredients, and allows for quick drying. Begin by placing your brush on the corner of the top lid, on top of the eyelashes, and move the color in one direction. If you desire a fine line, lightly touch the brush to the skin around the eye. For a thicker more defined look press firmly. Repeat this process to the lower lid only keeping the color under the lashes.
