Does Makeup Expire?
Yes, all makeup expires. Mascara lasts 3-6 months, liquid foundation 6-12 months, lipstick 1-2 years, and powder products 2+ years. Expired makeup can harbor bacteria, cause breakouts, eye infections, or skin irritation. Look for the PAO (period after opening) symbol showing months of safe use.
Key Takeaways
- Makeup expiration varies by product type.
- Natural and preservative-free cosmetics may expire faster than conventional products.
- Pencil products last longer because sharpening removes contaminated surfaces.
Explanation
Makeup expiration varies by product type. Wet products like mascara, liquid eyeliner, and cream products expire fastest because moisture supports bacterial growth. Powder products like eyeshadow, blush, and powder foundation last longest because dry environments inhibit bacteria.
The PAO symbol (an open jar icon with a number like '12M') indicates months of safe use after opening. Many products also have traditional expiration dates. Track when you open products, especially mascara and liquid eyeliner that touch eyes.
Signs of expired makeup include changes in smell, color, or texture; separation of ingredients; or decreased performance. Eye products should be replaced after any eye infection. When in doubt, throw it out - the cost of new makeup is less than treating an infection.
Things to Know
- Natural and preservative-free cosmetics may expire faster than conventional products.
- Pencil products last longer because sharpening removes contaminated surfaces.
- Store makeup in cool, dry places; bathroom humidity can accelerate degradation.
