When Does Makeup Expire? A Product-by-Product PAO and Decluttering Checklist

Overview

Makeup does not become unusable on one universal date. Its useful life depends on the formula, packaging, frequency of use, storage conditions, and how easily the product is exposed to air, moisture, skin, or the eyes. A product used with clean hands and stored in a cool, dry place may remain pleasant for longer than one kept in a hot bathroom, but storage cannot make an expired product new again.

Start with the packaging. Look for a printed expiration or best-before date where provided, then check for the period-after-opening (PAO) symbol: an open jar marked with a number and the letter “M,” such as “6M” or “12M.” This indicates the suggested period of use after opening. Record the date you first opened the product, rather than the date you purchased it. If the label gives a shorter or more specific instruction, follow the label.

These time frames are practical starting points, not guarantees. When a product shows a noticeable change in smell, color, texture, separation, or performance—or causes irritation—stop using it regardless of the calendar. Products used around the eyes deserve the most cautious approach because contamination can be difficult to see.

What to track

A basic inventory can be kept in a notebook, spreadsheet, or note on your phone. For each item, record:

• Product and shade: Include the formula, such as waterproof mascara, liquid foundation, cream blush, or pressed powder.
• Date opened: Use the first day you used the product, even if it was only a single application.
• PAO or printed date: Copy the symbol or date from the packaging so you do not have to search for it later.
• Storage conditions: Note whether it lives in a cool drawer, a humid bathroom, a makeup bag, or a warm car. Heat, sunlight, and moisture can affect formulas and packaging.
• Hygiene risk: Flag products that touch the eyes, lips, or broken skin, and products applied with fingers or reusable tools.
• Current condition: Add a short note about smell, texture, color, separation, and how the product performs.

Typical review windows by product type

The following ranges are commonly used as a conservative organizing guide. Check the individual product label first, and treat any visible or sensory change as a reason to discard the item sooner.

• Mascara: Review after roughly three to six months, with extra caution because the wand repeatedly enters the tube and the product is used close to the eyes. Do not add water or another liquid to revive a drying formula.
• Liquid eyeliner: Review around three to six months, or earlier if the tip becomes crusty, the formula changes, or application becomes uneven.
• Gel eyeliner and cream eye products: Review after roughly six months. These products can collect moisture and are used near the eye, so changes in odor or texture matter.
• Liquid foundation and liquid concealer: Review around six to 12 months. Pump packaging generally limits direct contact better than a jar, but it does not remove the need to monitor the formula.
• Cream blush, cream bronzer, and cream highlighter: Review around six to 12 months. Products applied with fingers need particularly careful handling and should not be used over irritated or broken skin.
• Pressed powder, powder blush, bronzer, and eyeshadow: Review around 12 to 24 months. Powders may last longer than liquids, but repeated contact with oily brushes can create a hard surface or change how the product applies.
• Lipstick and lip liner: Review around 12 to 24 months. Pay attention to waxy, sour, or unusual odors, sweating on the surface, dragging during application, or a change in texture.
• Lip gloss and liquid lip color: Review around six to 12 months. The applicator returns to the tube after touching the lips, making hygiene and smell important indicators.
• Makeup sponges: Replace when they remain stained, develop an odor, tear, or cannot be cleaned thoroughly. Wash them according to the manufacturer’s guidance and allow them to dry fully.

Brushes are reusable when cleaned and dried properly, but they still belong in your inventory. For a practical cleaning schedule and replacement signs, see How to Clean Makeup Brushes and Sponges.

Cadence and checkpoints

A quarterly check is simple enough to maintain and frequent enough to catch forgotten products. Set aside 15 to 20 minutes at the start of each season. Work by category rather than pulling out the entire collection at once.

1. Check eye products first. Remove mascara, liquid eyeliner, and cream eye products from your storage area. Compare their opening dates with the label and inspect the applicators.
2. Review liquids and creams. Shake or mix only as the packaging directs. Look for separation that does not resolve normally, curdling, lumps, unusual thinning, or a new odor.
3. Inspect powders. Look for hard pan, dampness, mold-like spotting, or a persistent film that prevents the product from picking up on a clean brush.
4. Check lip products. Inspect both the bullet and applicator. Discard anything with an unusual smell, visible contamination, or a texture that has changed significantly.
5. Clean the storage area. Wipe drawers and organizers, wash tools, and allow damp items to dry completely before returning them.
6. Update the inventory. Mark items to use soon, items to replace, and products you no longer enjoy or reach for.

Perform an extra check after a move, a heat wave, a long period in a humid bathroom, or an illness affecting the eyes or lips. If an item has been shared, dropped open, or touched by an unclean tool, move it higher on your review list.

How to interpret changes

Packaging and performance often provide the clearest clues. A foundation that suddenly separates, smells sour, or applies in uneven patches should not be kept simply because its PAO window has not passed. A cream product that develops beads of liquid, a lipstick that becomes unusually dry or greasy, or a powder that stays damp may no longer be in good condition.

Color shifts can be harder to judge because some formulas naturally darken or oxidize after application. Compare the product with an unused area of the same item when possible, and consider whether the change is visible before use or only after it meets the skin. If the difference is accompanied by a new odor or texture, discard it.

Do not try to extend a product’s life by adding water, oil, saliva, or skincare. These additions can alter the formula and introduce contamination. Avoid sharing eye and lip products, and never use makeup on skin that is actively irritated, cracked, or infected. If a product causes burning, swelling, itching, or a rash, remove it and stop using it; seek professional medical advice if symptoms are severe or persistent.

When deciding between “keep” and “discard,” use this order: follow the label, consider the opening date, assess storage and hygiene, then trust meaningful changes in the product. The cost of replacing one item is less important than continuing to use something that no longer seems clean or stable.

When to revisit

Return to this checklist quarterly, and sooner for eye makeup or products stored in warm, damp conditions. Add an entry whenever you open a new item. A small label on the base of a tube or palette can make the next review easier: write the month and year, such as “opened March 2026.” For products with a PAO symbol, write the expected review month beside it.

Use the following quick decluttering checklist:

• □ I recorded when the product was opened.
• □ I checked the printed date or PAO symbol.
• □ The smell is normal for this formula.
• □ The color and texture are consistent.
• □ The product applies as expected.
• □ The packaging is clean, closed, and undamaged.
• □ The item has not been exposed to unusual heat, moisture, or contamination.
• □ I have cleaned the tool used with it.
• □ I would choose to use it on my face or eyes today.

Discard items that fail a safety or condition check, then update your inventory so the same product does not reappear in the next audit. A seasonal review keeps your collection easier to use, makes everyday makeup routines more efficient, and helps you notice which products are genuinely worth repurchasing.
