I'm on my second tube of this, and about to purchase my third. After hitting 35 my lases seemed to fall out over night, and my once gorgeous, thick, long lashes looked sparse and sad. I bought this in desperation, not wanting to get a RX that would make my green eyes turn different colors. This works really well for me. People ask me if I use fake lashes a lot, but I did used to have amazing lashes originally, so I'm not sure if everyone will get the same results. I use it every night and one tube lasts about 6 months. I did stop using this once, and my lashes started to fall out again after a few weeks, so you do need to continue to use this. Price is pretty expensive, about 42$, but I figure that 7$ a month for good lashes is a reasonable cost. Packaging is good. One thing is that the conditioner side never bothers my eyes, but the solution side can irritate my eyes if I get it in them, so I apply carefully. Will repurchase.
