How long can you keep lipstick before it goes bad?

As a cosmetic expert with a keen eye on product safety and longevity, I understand the importance of maintaining the quality and safety of makeup products, especially lipsticks. Lipstick is a staple in many beauty routines, and it's crucial to know how long you can use it before it becomes unsafe or less effective.

Lipstick Shelf Life

The general rule of thumb for lipstick and lip liner is that they typically last for about one year. This is due to several factors that can affect the quality and safety of the product:


1. Exposure to Bacteria: When you apply lipstick, it comes into contact with your lips, which can harbor bacteria. Over time, this can lead to contamination of the product, which may not be visible but can lead to potential health risks.


2. Degradation of Ingredients: Lipstick is made up of various ingredients, including oils, waxes, and pigments. Over time, these ingredients can break down, which can affect the texture, color, and performance of the lipstick.


3. Changes in Texture and Appearance: As lipstick ages, you may notice changes in its texture, such as becoming dry, hard, or crumbly. It may also separate or develop an odd smell, which are signs that it's time to toss it.


4. Expiration Date: Always check the packaging for an expiration date. Manufacturers often provide a "period after opening" (PAO) symbol, which is a small jar with a number and an "M" inside it, indicating the number of months the product is safe to use after it has been opened.

**Signs It's Time to Toss Your Lipstick**

Here are some signs that your lipstick may have gone bad:

- Unusual Odor: If your lipstick starts to smell off or develops a strange odor, it's a sign that it's time to replace it.
- Change in Texture: If it becomes too hard to apply or starts to crumble, it's likely past its prime.
- Separation of Product: If you notice the lipstick separating or looking oily, it's a sign of degradation.
- Mold or Fungus: If you see any signs of mold or fungus, discard the lipstick immediately.

Storage and Care

Proper storage and care can help extend the life of your lipstick:

- Keep It Clean: Always remove any excess lipstick from the bullet before closing the cap to prevent the product from being exposed to air and bacteria.
- Store in a Cool, Dry Place: Avoid leaving your lipstick in hot or humid environments, as heat and moisture can accelerate the degradation process.
- Avoid Sharing: Sharing lipstick can introduce bacteria and lead to contamination.

Alternative Uses

If you find that your lipstick is nearing the end of its life but isn't quite ready for the trash, consider these alternative uses:

- As a Blush: You can use the lipstick as a cream blush by applying it to the apples of your cheeks and blending it out with your fingers.
- For Art Projects: It can be used in various art projects, such as painting or crafting.
- As a Lip Stain: Apply it to your lips and blot with a tissue to create a long-lasting stain.

In conclusion, while lipsticks are generally safe to use for about a year, it's essential to monitor them for signs of degradation and to practice good hygiene to ensure their safety and effectiveness. Remember, your health and the quality of your makeup experience should always come first.
