Patience is the name of the game when it comes to lash serums. “You won’t see overnight results from eyelash growth serums, which require consistency and patience,” board-certified dermatologist Dendy Engelman, MD, who is based in New York City, previously told Allure. “To see optimal results, you should apply the serum one to two times per day for at least six to eight weeks, and you’ll see the best results around the 12- to 16-week mark.”

And after using Nulastin LASH Follicle Fortifying Serum—formulated with powerful peptides, hydrating glycerin, and strengthening keratin—twice a day for at least six weeks, you’ll notice longer, more lush-looking lashes, no mascara required.

With the brush applicator, draw a thin line from the inner corner to the outer edge on the upper lash line only. Repeat morning and night on clean, dry lids.
