stasla asked: how long do you keep a mascara before throwing it out, and how many mascaras do you keep open at once? I like having multiple ones open so I can use whichever one feels appropriate for my makeup that day, but then I worry they'll go bad. :(
I keep mascaras for about three months before tossing them and I have anywhere from two to five mascaras open at a time. I generally use drugstore mascaras so I don’t feel a ton of guilt if I have to throw a tube away before using it up and I have no problem throwing mascara away if it gets clumpy or flaky before its time.
Have you ever used the Beauty Alert iphone app? It lets you catalog your makeup and skincare with detailed info (including photos) and it automatically alerts you when your products have reached their expected expiration date. I don’t always follow the app exactly (I prefer to use scent, consistency, and color as a guide if I want to keep something a little while longer), but it’s a great tool for keeping track of how long you’ve had a product and I find it most helpful when it comes to something as bacteria-prone as mascara.
