Technically, we're not supposed to do our water line. I'm a nurse and along the road in my career I worked for a derm md for several years. He used to preach ad nauseoum about many things but, some things I agreed with. Water line was one of my pet peeves in a way because of infections college kids came in with. But, I was in college it was common practice for us to share make up. Because it's technically open skin and close to the tear duct. That's how any bacteria enters and we end up with anything from an irritation to a case of pink eye, sinus infection or worse. With all that said I have two pencils I use that I won't share with anyone. They are both chubby sticks so, you've got to be careful. both from Benefit. One called "Mr. Frosty" and the other is "Bright Eyes". The lighter colors are supposed to brighten the whites of our eyes thus, taking the attention off a dark circle, puffiness. Hope this help!
