Using expired makeup can irritate skin and cause breakouts or infections. Learning to read dates and batch codes keeps your collection safe and fresh.
Find the PAO Symbol
The little open-jar symbol with a number like 6M or 12M shows the period after opening — how many months the product stays good once you start using it.
Look for Expiry or Manufacture Dates
Some products print a clear expiry date. Others show a manufacture date or a batch code you can check online to find production and expiry details.
Signs a Product Has Gone Off
- Change in smell, colour or texture
- Separation or clumping
- Irritation when applied
General Shelf Life
Mascara lasts about 3 to 6 months, liquid foundation around a year, and powders longer. When in doubt, throw it out.
The Takeaway
Check the PAO symbol, dates and batch codes, and trust your senses — fresh products keep your skin happy.
