- Long Lash eyelash enhancer is designed to dramatically enhance the look of your natural lash length, fullness & thickness. You will see visible results in just two to four weeks! Blinc Long Lash eyelash enhancer can be used up to twice a day, in the morning or at night, and should be applied to the base of the lashes, as you would apply an eyeliner. Only a small quantity of our Long Lash eyelash enhancer serum is needed to achieve the desired results. Long Lash should be used on clean and dry skin. If applying in the morning, allow blinc's Long Lash serum to dry completely prior to applying makeup like our liquid eyeliner pen and amplifying tubular mascara. Unlike other lash formulas, our eyelash enhancer causes no stinging or irritation. It also will not cause skin or eye discoloration. Blinc Long Lash natural eyelash enhancer will make your natural lashes appear longer, fuller, thicker and denser, not to mention healthy and conditioned. Use the eyelash enhancer serum daily for the dramatic, beautiful lashes you've always longed for! Remember, only a small amount of Long Lash is required and avoid direct contact with the eye.
