One of the most common beauty annoyances is to finally find a product that you love . . . and then see it discontinued. I've been traumatized a number of times by the sudden disappearance of lip glosses, fragrance sprays, and volumizing mousses that I adored. Everybody eventually moves on and finds something else they like, but that doesn't mean that the loss is any less keen. (Kind of like relationships, I guess.) What about you? Is there a product that disappeared from the shelves that you're still mourning to this day?
