There comes a time in every woman’s life when she must come to terms with the way she looks when she wakes up in the morning. I'm eager to try any product that may help my cause, especially when it comes to disguising wimpy eye lashes. Tarte Cosmetics' 4 Day Stay is great for occasions when you're going swimming or plan on waking up next to people you want to impress. You can commit the greatest beauty sin of all while wearing this mascara-stain hybrid: Sleep in it (just be wary of your white pillowcases as some testers reported a bit of smudging). PolyFlex technology allows mineral derived pigments to adhere to the lashes for an extended period of time. The formula is fortified with provitamin B5, which keeps them soft and lush.
