Review (5/5): Try this
I've tried 4 serums, all different brands. This one does not cause your eyelashes to fall out in the beginning to regrow. No eyelashes were lost! There is no burning sensation either. Now comes the tricky part ... do your eyelashes grow longer? Yes, but it takes time. Be patient. Apply twice a day, for 6 weeks. I love the results. I will purchase Zenlash in the future.
