You may be able to cut the tip off a lipstick if it’s the only part that’s discolored. However, it’s best to just replace the entire tube.
You may also see moisture collecting inside the tube. This is also a sign it’s time to toss your lipstick.
Once a lipstick starts to stink, just throw it away. Otherwise, you’ll be smelling it on your lips all day and could ingest a spoiled product.
Your skin may have germs on it. Wash your skin before you test the lipstick. You might also remove the tip of your lipstick afterwards or sanitize it with a spritz of alcohol.
You can check the texture on your hand or wrist, but you may also need to press your clean finger lightly against the lipstick. In some cases, you can notice changes in texture by just looking at the lipstick. For instance, if you see gritty particles along the side of your lipstick, it’s probably bad.
Some matte lipsticks can leave your lips feeling dry even when they’re still good. However, you should have smooth, even lip color. If your lip color is flaky or patchy, replace your lipstick.
If you’re worried about cost, limit how many tubes that you purchase at one time. For instance, you might stick to a day color, a night color, and a nude option.
Since trends change, it may be time to update your color palette anyway. An unopened lipstick can last up to 5 years.
If you notice that your product is leaving your lips dry, it may be time to get a new tube of lipstick.
For instance, throw out a tube that you left in your car or under a hot sun.
