Sometimes being sentimental is a good thing. When it comes to that 15 year old favorite tube of lipstick, maybe not so good. There is an app for iPhone called “Beauty Alert!” that helps you learn when it is time to toss out your old cosmetics. If it doesn’t pass the “smell test” (is it rancid smelling?) or “sight test” (did it change color, separate or grow mold?) then the app maybe for you. It is a buck and ninety-nine cents, and worth every penny.
