What information should I record for each skincare product?

Four things cover almost everything: the date you opened it, the PAO (period after opening) from the packaging, any printed expiry date, and the date you bought it. The opening date plus PAO gives you the real countdown; the purchase date protects the sealed backups quietly ageing in a drawer. Price is optional but turns your empties into honest cost-per-use data.

Is a spreadsheet good enough for tracking skincare?

A spreadsheet works exactly as long as you maintain it, and most people stop within a few months because every new product means typing, and every finished product means remembering to update a row. Trackers that read receipts or product photos remove the data entry, which is the step where manual systems die.

How do I start tracking a shelf full of products I already own?

Do a one-evening audit: gather everything, bin anything that smells off or has visibly separated, then record what survives. For open products, estimate the opening month; an honest guess beats no date. For sealed products, record the purchase date if you can find the receipt or order history. From then on, only log products at the moment you open them, which takes seconds.

How to keep track of your skincare products

Last updated: 12 July 2026

Somewhere between the third serum and the second backup sunscreen, a skincare collection stops fitting in your head. You forget when things were opened, backups age quietly in a drawer, and money leaves in both directions: products binned half-full, and products rebought because you forgot you already owned one. Tracking fixes all three, and it takes far less discipline than people assume, if the system is designed around the one moment that matters.

Record four things, once, at the moment of opening

The opening date. Everything else hangs off this. The PAO countdown starts here, and it's the date nobody remembers three months later.
The PAO. The open-jar symbol on the packaging: 6M, 12M, 24M. It means months of safe use after opening.
The printed expiry date, if there is one. Whichever of PAO or expiry comes first is the real deadline.
The purchase date. The most skipped and most underrated. Sealed products age too, and the purchase date is the only clock a sealed product has. A receipt records it for free.

Optionally add the price. It feels like admin until the first time you finish a product and can see what it actually cost per month of use; that number changes repurchase decisions more than any review.

The one-evening shelf audit

Gather everything. Bathroom, bedside, handbag, the drawer. All of it in one place, once.
Triage. Anything that smells wrong, has separated, or changed colour goes in the bin without negotiation. Expired actives (vitamin C, retinol, SPF) are the priority: they don't just fade, they can irritate.
Record the survivors. Open products get your best guess of the opening month; an honest estimate beats a blank. Sealed products get a purchase date from your order history if you can find it.
Stop. The audit is a one-off. From now on the only habit is logging a product at the moment you open it, which takes seconds and happens a few times a month at most.

Spreadsheet, notes app, or tracker?

A spreadsheet genuinely works while you maintain it. The problem is the word while: every new product means typing a row, and inventory spreadsheets quietly die within a few months of enthusiasm. A notes app dies faster. The failure isn't carelessness; manual systems demand upkeep at exactly the moments life is busiest.

Dedicated trackers close that gap by removing the data entry. The good ones read a shop receipt or a photo of the product and fill the shelf themselves, calculate the countdowns, and remind you before something turns, so the system keeps working through the busy months when a spreadsheet would have gone stale. There is an honest comparison of the current options in our expiry tracker guide.

Disclosure: Hadakeo, which publishes this guide, is one of those trackers. You photograph a receipt and the haul lands on your shelf with purchase dates already recorded; opening a product is one tap; and each product shows a life bar counting down its PAO. The free tier covers a 15-product shelf: app.hadakeo.com.

What tracking gives you after a month

The immediate payoff is safety and money: nothing expires unnoticed and nothing gets rebought by accident. The quieter payoff arrives when you finish your first tracked product and answer one question: would you buy it again? A shelf tracked over months becomes a record of what actually earned its place, written by you rather than by marketing. It also makes sticking to the routine itself easier, because a shelf you can see is a shelf you use.

Common questions

Do I need to track cheap products too?

Track anything you put on your face. Expiry doesn't care what a product cost, and cleansers and SPF are among the most-used and soonest-expired items on most shelves.

What about backups I haven't opened?

Record their purchase date and, if printed, the expiry date. Sealed doesn't mean immortal; it means the clock runs slower. Use the oldest sealed product first.

Is this worth it for a small routine?

A five-product routine mostly fits in your head. The value appears around ten products or the first time you buy backups, which for most people is the same month they discover a favourite is being discontinued.
