I paid $200 for 2 kits. I have been using it 2 months and am still on the first kit. I saw results after the 1st month. Yes, I had a little itching at first, yes, my lids along the lashline are slighly pink and yes, I have a few lashes in the corner of my eyes where I obviously wasn't very careful about my application (I've since corrected that), but all of that said, I love the results!
I've had crapy little lashes all my life. Now they are definitely longer, and slightly thicker and darker. When wearing mascara, I look like I have on false eyelashes, a look I love. I am very pleased and recommend people who aren't happy with their current lashes at least try it!
