There has been a lot of debate over whether water proof mascara is good or if it makes your eye lashes fall out when you wear it. From my experience just normal water proof mascara hasn't been very good for me, yes it does stay on when I go swimming but after a while of wearing it, it starts to feel gross and then it sort of 'cakes' up on my eye lashes. Cover Girl has come up with a Mascara called "Washable Waterproof Mascara" it sounds impossible but it really does work and it works great! I can go swimming and my eye lashes will look long and gorgeous the whole time and I wont get any dark circles under my eyes. This Mascara will stay on for a long time and when you are ready to take it off it'll come right off with a cotten ball and some plain old water. I was amazed when I found this and it ended up being my favorite mascara, I had to get ride of all the other mascara's I was trying. I would recommend this product to anyone who doesn't like to worry about their mascara dripping down their face when they cry or go swimming. All you girls should try this one out.
