The INSIDER shared a very informative article on their website, stating “With the exception of a very good lipstick, makeup is not made to stay on all day. Nor is it designed to last forever.

Eventually, you’ll need to throw out your favorite beauty products and replace them with new ones. Old makeup loses its quality, becomes harder to apply, and can even become harmful to your skin and cause infections thanks to bacteria build-up.

Figuring out when you should throw away your beauty products is simple: Look at the packaging.

There’s a tiny symbol on the label that most people don’t even notice, which tells you how long your products will last after you’ve opened them. Look out for an open cream jar icon, known as the PAO (or “Period After Opening”) symbol, which includes the number of months a product is safe to use after it has been unsealed.”

The shelf lives of many foods, cosmetic and other consumable products are substantially shortened after opening the package, or after first use. However remembering when the package was opened, and therefore when to discard the product can be a challenge.

Our ‘Time from Opening Indicators’ face that challenge by reminding consumers exactly how long it has been since the product was opened and therefore, for how long it can still be used, via a simple and intuitive visual cue.
