Yes, lipstick does go bad.
An expired lipstick is more likely to harbor harmful bacteria and may no longer deliver the desired performance. It's important to check the expiration date on the lipstick packaging or at the bottom of the tube.
Why Lipstick Expires
Lipstick, like other cosmetic products, has a limited shelf life. Over time, its ingredients can degrade, leading to changes in texture, color, and scent. More importantly, it can become a breeding ground for bacteria, increasing the risk of skin irritation or infection.
How to Tell If Your Lipstick Has Expired
Here's how to determine if your lipstick has gone bad:
- Check the Expiration Date: Look for a PAO (Period After Opening) symbol on the packaging (a small jar icon with a number followed by "M," indicating months).
- Changes in Texture: If your lipstick becomes dry, crumbly, or develops a grainy texture, it's likely past its prime.
- Unpleasant Odor: A rancid or strange smell is a clear sign of spoilage.
- Altered Color: Noticeable changes in color or the appearance of a white film on the lipstick indicate it's time to discard it.
Risks of Using Expired Lipstick
Using expired lipstick can lead to several issues:
- Bacterial Infections: Expired lipstick can harbor bacteria, leading to lip infections, cold sores, or allergic reactions.
- Skin Irritation: The degraded ingredients can cause dryness, chapping, or a rash on the lips.
- Poor Performance: Expired lipstick may not apply smoothly, provide the desired color payoff, or last as long as it should.
Best Practices for Lipstick Hygiene
To extend the life of your lipstick and minimize the risk of contamination, consider these tips:
- Store Properly: Keep your lipstick in a cool, dry place, away from direct sunlight or heat.
- Sharpen Regularly: Sharpening your lipstick regularly can remove the top layer, which may be contaminated.
- Avoid Sharing: Sharing lipstick can spread bacteria and increase the risk of infection.
- Clean Application: Apply lipstick with a clean brush to avoid direct contact with your lips.
