It takes me a year or longer to finish my go-to eyeshadow for filling in my brows! I’ve never finished a blush before, though MAC Margin has the most pan showing, and that was one of the only blushes I owned for years. For lipstick, I would say a year or longer if it’s in regular rotation. Gloss would be a bit less – but I just don’t use anything consistently enough to finish.
