Works but doesn't last
I watched other people applying this on YouTube videos prior to purchasing.  I think it works well, however, it only lasts a day or 2 on the skin.  My eyebrows, themselves, remain dyed, but the nice, filled-in look I achieved after completing the process only lasted a few days and I was hoping it would last at least a week .  I will make this part of my Sunday night routine, but I'm somewhat disappointed.  I do know that my brows, and skin are resistant to dyes so the next time I apply it I'm going to leave it on for 15 minutes.  The first time I applied, I followed the package directions, leaving it on 4-5 minutes, but ended up reapplying several times.
