I've been using this about a week now, in the morning and before going to bed. It does work as claimed, It just takes consistency with use and following the directions. The bottle should also last me a good month and a half before having to order more. You all should try these, I've never actually been a fan of false lashes and while I will wear them, I'd rather just enhance my own. This and castor oil are a great mix for longer eyelashes!
