Product Shelf-Life & PAO Tracker
Log when you opened a product and its open-jar PAO symbol to see its use-by date, the days left, and whether it’s still safe to reach for.
Use it by
Natural and preservative-light formulas can turn sooner than their PAO suggests. Trust your senses: a changed smell, colour, or texture means stop using it, whatever the date.
Fresh is part of clean
Choosing gentle, minimally preserved formulas is one of the pleasures of natural beauty — but it comes with a catch: those products don’t last forever, and a spoiled oil or serum can irritate skin as surely as any harsh ingredient. The period-after-opening symbol is the manufacturer’s estimate of how long you have once the jar is opened, and it’s easy to lose track of across a shelf of half-used bottles.
This tracker turns an open date and a PAO into a clear use-by, counts down the days, and nudges you when a product is getting close — so nothing lingers past its best and your routine stays fresh.
Frequently Asked Questions
What is the PAO symbol?
PAO stands for period after opening — the small open-jar icon on cosmetic packaging with a number like 6M, 12M, or 24M inside. It tells you how many months the product is designed to stay good once you've opened it and started exposing it to air and skin. Enter that number and your open date and the tracker works out the use-by date.
Do natural products expire faster?
Often, yes. Formulas with few or gentle preservatives, cold-pressed oils, and botanical extracts can oxidise or spoil sooner than heavily preserved conventional products — which is part of why tracking the open date matters. Store them cool and dark, keep fingers out of jars, and treat the PAO as an upper bound rather than a promise.
Should I ever toss a product before its use-by date?
Absolutely. The date is a guide, not a guarantee. If a product smells off, changes colour, separates and won't remix, or its texture turns, stop using it regardless of the date — especially anything used around the eyes. When in doubt, throw it out.
Is this safety advice?
No. The tracker is an organisational tool based on the PAO you enter, not medical, dermatological, or product-safety advice. It can't judge how a specific product was stored or formulated. Follow the manufacturer's directions and your own senses, and see a professional if a product causes a reaction.
Organisational estimate only, not medical, dermatological, or product-safety advice. Storage and formula change real shelf life; trust a changed smell, colour, or texture over any date, and stop using anything that reacts.
