No, using 10-year-old lipstick is generally not recommended. While some sources mention people using lipsticks several years old without issue, the consensus from multiple sources including the Mayo Clinic Health System suggests that lipstick should be discarded after one to two years.
Why Discard Old Lipstick?
Several factors contribute to the recommendation against using old lipstick:
- Bacterial Growth: Lipsticks, even if barely used, can harbor bacteria over time. Using old lipstick increases the risk of skin irritation or infection.
- Formula Degradation: The ingredients in lipstick can break down over time, altering the texture, color, and smell. This may make it less effective or even unpleasant to use. A crayon-like smell is often cited as an indicator of degradation.
- Safety Concerns: While some individuals may have used very old lipstick without apparent harm, the potential risks outweigh the benefits. There's no guarantee of safety with significantly aged products.
Exceptions and Considerations
While discarding is recommended, some sources note that if a lipstick remains in good condition (no unusual smell, changes in consistency or appearance, or visible mold), it might be usable beyond the recommended timeframe. However, this is not advisable, and using an exceptionally old product is inherently risky.
- Sensory Check: Always check the smell and texture before using any older lipstick. Discard immediately if you detect any off-putting odors or changes in consistency.
- Visual Inspection: Look for signs of mold or discoloration. Any unusual appearance should trigger discarding.
It's crucial to prioritize safety. Using old cosmetics carries an increased risk of skin irritation, infection, or other adverse reactions. The potential risks associated with using 10-year-old lipstick significantly outweigh any benefits. Replacing your lipstick every one to two years is a best practice.
