I had some doubts, especially since I didn't notice any real growth in five weeks. Then this past weekend, I looked at my lashes again and noticed that the outer edge lashes and a few in the middle look significantly longer than before. They don't quite match the thickness of my other lashes. Looking at a side view mirror, the difference is hardly noticeable, but with some mascara, there is a difference. I'll keep going with this and hopefully I'll see some more growth.
I paid $75 for two bottles of Lumigan. I apply it with a #1 sable brush I bought from an art supply shop. I don't think I even used 1/4 of the bottle yet. All I need is a small drop on a sheet of plastic and it's enough to soak the lash lines of both eyes, top and bottom. My eyes do get red from it, but if I stop using it for a few days, they clear up right away.
