Did you know that a typical mascara dries up before even half of it is used up? Do you have multiple mascaras going at once and fear that they will dry out on you? Well never fear, there's a fix for that!
It's very important to remember that all mascaras should be thrown out every 3-6 months depending on the level of usage (ones you use most should be thrown out sooner).
You will only need Saline solution or Visine (any kind of gentle eye drops will do or contact solution). When your favorite mascara starts to get dry and clumpy just add 5-6 drops of saline solution or eye drops to the bottle. Put your wand back in, close tightly and shake! You can do this multiple times until you finish all of your mascara.
