How to Organize Your Skincare and Makeup Collection (Waste Less)

Most of us have one: a drawer, basket or bathroom shelf full of half-used serums, three nearly identical lipsticks, and a sunscreen of unknown age. Learning how to organize your skincare and makeup collection isn’t only about looks. A tidy collection means you use products while they’re still at their best, you stop buying things you already own, and you’re less likely to put something past its prime on your skin.

Here’s a simple system that works for any size of collection.

Key takeaways

• Gather everything in one place, sort by category, and check each product before deciding to keep it.
• Learn the labels: the open-jar PAO symbol shows how many months a product lasts after opening, and sunscreens carry an expiration date.
• Toss products that have separated, changed color or smell, crumbled or clumped, and replace mascara about every three months.
• Store products in a clean, dry place at room temperature, away from direct sunlight and steamy bathrooms.
• Write down opening dates and check your shelf before you shop to avoid duplicates.

How to organize your skincare and makeup collection in 7 steps

Step 1: Take everything out

Collect every product you own from the bathroom, bedroom, handbags, gym bag, travel pouch and car. Seeing it all together is often the moment people realize they have four open cleansers.

Group items by category: skincare, makeup, haircare, fragrance, body care, sun care, nails and tools. Then sort each group by type, like cleansers with cleansers and foundations with foundations.

Step 2: Check what’s still good

Read the symbols

• Period after opening (PAO). A small open-jar icon with a number and the letter “M” tells you how many months a product is meant to last after you first open it. A “12M” jar means 12 months. Our guide to the PAO symbol and how to calculate it explains it in more detail.
• “Best used before the end of” dates. Under the EU Cosmetics Regulation (EC) No 1223/2009, products with a minimum durability of 30 months or less must show this date, either after a dedicated symbol or after those words. Products that last longer carry a PAO instead, unless it doesn’t apply (single-use items, for example).
• No date at all? That’s normal in the U.S. The FDA says no U.S. laws or regulations require cosmetics to have expiration dates, and the American Academy of Dermatology (AAD) notes that PAO information isn’t required there either.
• Sunscreen is different. The AAD explains that the FDA requires sunscreen to keep its original strength for three years, and many carry an expiration date. Toss sunscreen once it expires. If it has no date, write the purchase date on it.

Signs a product is past its best

Even within its dates, a product can go off early. Use your senses as you sort. The AAD’s advice is to let go of anything that has clumped (a common fate for mascara), separated into layers, crumbled, turned dry and flaky or oddly runny, changed color or smell, or started to feel different on your skin.

The FDA adds that temperature changes, sunlight and air can change a product’s color, texture and smell.

Eye makeup gets extra care

The AAD suggests replacing mascara about every three months, and the FDA notes that manufacturers usually recommend two to four months after purchase. If mascara dries out, throw it away. Never add water or saliva, which can introduce germs. The FDA also advises throwing away your eye makeup if you get an eye infection.

Step 3: Sort into keep, use up and let go

• Keep: in date, in good condition, and something you actually use.
• Use up first: opened products getting close to the end of their PAO. Put them at the front.
• Let go: expired, spoiled, or products that irritated your skin.

Before you toss something, ask why it didn’t work. Wrong shade? A duplicate? A trend buy? Those answers are your shopping list of what not to buy next time.

Step 4: Store products where they’ll last

Where you keep products affects how long they stay good. The AAD recommends storing cosmetics in a clean, dry place at room temperature, out of direct sunlight, with caps and lids closed tightly. The FDA points out that moisture, like in a bathroom, can make it easier for bacteria and fungi to grow. Heat is a problem too. A hot car can break down sunscreen ingredients before the expiration date.

Some practical setups:

• A daily tray for each routine. Keep morning products together and evening products together, in the order you use them.
• A cool, dry spot for backups. A bedroom drawer or cupboard away from windows works better than a steamy bathroom shelf.
• Clear containers and dividers, so nothing gets lost at the back.
• Front-to-back by opening date. Oldest in front, newest behind.
• A travel kit kept separate, so you don’t open a second of everything for trips.

Step 5: Label the day you open it

To know when a PAO runs out, you need the start date. Dermatologists recommend keeping track of when you open each product. A small sticker or a note on the base works, or a digital log if you’d rather not write on your packaging.

Step 6: Keep your tools clean too

A tidy collection needs clean tools. The AAD suggests washing makeup brushes every 7 to 10 days and cleaning makeup sponges after every use. Wash your hands before applying products. And don’t share makeup, which the FDA and AAD both advise against because it can spread germs.

Step 7: Shop your shelf before the store

The easiest way to waste less is to buy less of what you already have:

• Check before you buy. A quick look at your shelf, or your notes, saves you from buying a fourth nearly identical serum.
• One in, one out. Finish, or deliberately let go of, one product before you open its replacement.
• Keep a wishlist. Adding something to a list instead of the cart gives you time to decide whether you need it.
• Limit backups. Even unopened products don’t last forever, so only keep a spare of the things you use daily.

If your shelf is overflowing with serums, it may be a sign your routine has more steps than your skin needs. Paring back to a cleanser, moisturizer and sunscreen, plus one treatment, makes the next shopping trip much simpler.

How Skinchii can help

This is what Skinchii, your beauty buddy app, was built for. Add products to your shelf by scanning the barcode or searching Skinchii’s catalog of 4,500+ curated products from 2,700+ brands, or enter them manually. Each product can have photos, a storage location, notes and a status (active, archived, finished or discarded). Add the printed expiry date, the PAO and the day you opened it, or whichever of these you know, and Skinchii calculates the best-before date, using whichever date comes first. An expiring-soon, expired and low-stock center, plus alerts, tells you what to use up first. Duplicate detection flags products you already own, and your wishlist, with priorities and an easy move to your shelf once you buy, keeps impulse buys in check.
