Doesn't last :-( [SEP] I can see this product being of use for someone with thick brows. Me on the other hand, I was foolish to think this formula would be akin to getting a temporary eyebrow tattoo. I lasted all of 2 days. My daughter who has thicker brows was able to get it to last for about 4 days. We are both heavy exfoliator users, so I'm sure that made this stuff fade even faster. It was worth a try though, and its ok if you need a temporary fix.
