the answer: The risk of your lipstick formula spoiling (or growing bacteria) is low since they don’t contain any water… But, since you use them so often and they’re exposed to your mouth area, you should replace lip products after a year, or if you’ve recently been sick. Lipsticks and glosses contain oily ingredients that start to smell like stale cooking oil over time, and you should look out for changes in texture.
You’ll know a lipstick has gone bad when it gets hard and you can’t spread the pigment on your lips; lip gloss will feel streaky and globby if you try to apply it.
