7. Makeup Expires Only When It Smells Bad

It’s a mistake to assume makeup is still safe as long as it smells and looks normal. Most cosmetics have a specific shelf life, indicated by a Period After Opening (PAO) symbol on the packaging, such as “6M” for six months. Expired makeup can harbor bacteria and cause skin irritation or infections, even if there are no obvious signs of spoilage.
The FDA recommends discarding products after their recommended period and never sharing makeup to prevent contamination. Always check expiration dates and follow manufacturer guidelines to protect your skin and overall health.
