I am honestly still not sure if this stuff is really doing anything. I've been using it for a couple months now and I think my brows have filled in a little? One of them is definitely easier to fill in with my pencil. The other still has two significant sparse areas, though, that don't seem to be affected at all. I think I'm going to use up this tube and then just stick to the cheaper stuff from The Ordinary to see if I notice a difference.
