We all know that mascara doesn't last forever. It's not even sanitary to use for too long. But sometimes, we must admit that an expensive tube dries out a lot quicker than we'd like. There should be a way to refresh it, we feel. And we're right, there is a way to get things flowing once more. The hack just uses some of the contact solution you already have on your nightstand.
Put a few drops in the tube, and pump and shake it up. Put that tube in a mug of hot water for a few minutes. Then, pump it again and it will be good as new, or close to it!
