I wouldn't say I saw a significant improvement in the amount of lashes or length of my lashes while using this product but my lashes were plumper and felt stronger and well conditioned. They had much more curl and were very healthy even after just one week of use. The instructions are true though: diligent and continued use is the key. It stings a little when you put it on but that goes away after a few blinks.
i didn't like this product very much. it made the sensitive skin around my eyes itch, and when i did rub my eyes my eyelashes would fall out. not a fan at all.
i really enjoyed this product and all of it's multiple uses. I like to use it to brighten my eyes when tired or as a bit of concealer on red areas
