I actually bought mine at Kohl's but next time I will buy through Amazon. This stuff is amazing!!!!! I've been using it twice a day for a month and feel like I need to back off because my lashes are getting too long (is that even possible?!) lol. I really didn't think it was going to work this well. It takes about 2 weeks to start seeing results. I almost don't need mascara anymore but I still use it to make my lashes darker. Definitely don't need lengthening anymore. I also noticed that the amount of lashes has tripled. My lashes were a wreck before I started using this stuff. Year of mascara, soap, and makeup remover had all but eliminated my lashes so I'm ecstatic that I found something affordable to help regrow them. I can't say enough good things about this stuff. It also comes with a lot of product in the bottle so it will last a long time. Like I said, I've been using it for a month and I can hardly tell that any product has been removed from the bottle.
