The average woman owns 40+ beauty products, but keeping on top of what we own and when we started using it – that's a whole different story! And while using expired makeup can seem harmless it can actually mean breakouts, skin rashes, or just a product that's lost its efficacy. Here’s your guide to keeping your beauty musts as safe as possible!
Code 1: THE LITTLE JAR symbol: aka "PAO = Period After Opening"
What it means: The “Period After Opening” symbol indicates a number + M = months the product stays good after you break the seal.
Common ones: 6M (mascara, liquid liner), 12M (foundation, lipstick), 24M (powders, eyeshadow).
Why it matters: Preservatives break down once air hits it. A 24M foundation opened you’ve been hanging on to since 2016? Toss it.
tip: Eye products are the strictest — any change in smell, texture, or color = done, regardless of the number.
Expert Hack: Write the opening date in a Sharpie on the bottom of your product, or snap a photo of it on your camera roll so you can refer back and know you opened it.
Code 2: The Mobius Loop.
What it means: You can recycle some, or all, of the packaging.
The chasing-arrows triangle with a resin number (1, 2, 5 = usually yes; 7 = usually no)
Expert tip: Explore brand-specific take-back programs like TerraCycle, MAC’s Back-to-MAC, Kiehl's.
Code 3 — The Best Before Date Stamp.
What it means: BBE “Best Before End” date — the product has a shelf life under 30 months even unopened. Look for a date next to it.
Expert tip: Often this date stamp appears only on the exterior packaging or box, not on the actual product itself so be sure to use your sharpie and write on the product when you started using it, or again create a “Beauty products” photos folder in your phone, and snap a photo of the product. That way, you’ll have a record of when you started using it.
Code 4: Leaping bunny certified logo
For those that want to shop consciously, this symbol indicates that the product is cruelty free according to LeapingBunny.org.
Expert tip: There are other governing bodies out there but in my research, Leaping Bunny is the most thorough.
Code 5: Seal of Acceptance from the Canadian Dermatology Association.
What it means: With this seal of approval from the Canadian Dermatology Association, you can have peace of mind that your SPF is vetted, and it is living up to the claims on the label.
This seal is a useful one to be on the lookout for, especially as warmer weather is upon us and you’re shopping for sunscreen.
