Wondering how long makeup lasts? This product-by-product expiration and PAO checklist helps you record when each item was opened, recognize changes that call for replacement, and build a simple quarterly makeup-bag cleanout routine.
Overview
Makeup does not have one universal expiration date. The useful starting point is the product’s packaging: look for a printed expiration date, a batch or lot reference, and the open-jar symbol showing a number followed by “M,” such as 6M or 12M. This period-after-opening (PAO) symbol indicates how long the product is generally intended to remain suitable after opening when it is stored and used as directed.
Use the manufacturer’s label as the primary guidance. If the label is missing, unreadable, or the product has changed in smell, color, texture, or performance, a cautious replacement is usually more sensible than trying to extend its life. A product can become contaminated before its expected PAO period ends, particularly when it is repeatedly touched, exposed to moisture, shared, or stored in heat.
The timelines below are practical planning ranges, not guarantees. They assume normal personal use, clean hands or tools, a tightly closed container, and storage away from excessive heat and humidity. Eye products and liquid or cream formulas deserve the closest attention because they are more vulnerable to contamination and formula changes.
What to track
For each item, record the product name, shade if relevant, date opened, PAO or printed expiration information, storage location, and any change you notice. A small label on the base or a note in your phone is enough. If you cannot remember when a product was opened, mark it as “unknown” and assess it more conservatively.
| Product | Typical planning range after opening | Replace sooner if you notice |
|---|---|---|
| Mascara | About 3–6 months; follow the package first | Drying, clumping, unusual odor, a changed wand, or eye irritation |
| Liquid eyeliner | About 3–6 months | Skipping, drying, odor, separation, or discomfort around the eyes |
| Gel eyeliner | About 6–12 months | A dry surface, cracking, odor, or difficult application |
| Liquid foundation | About 12 months, depending on the label | Persistent separation, odor, color shift, or a grainy texture |
| Liquid concealer | About 6–12 months | Separation, drying at the applicator, odor, or irritation |
| Powder foundation, blush, and eyeshadow | Often about 18–24 months | A hard film, strong odor, moisture exposure, or poor pickup |
| Cream blush, bronzer, and highlighter | Often about 6–12 months | Rancid odor, sweating, separation, mold, or a changed feel |
| Lipstick and lip liner | Often about 12–24 months | Rancid or waxy odor, sweating, crumbling, or a changed texture |
| Lip gloss and liquid lip color | Often about 6–12 months | Stringiness, separation, odor, or an applicator that looks contaminated |
These ranges help with organization; they do not override a product-specific label. Products used on the eyes should not be “rescued” with water, mixing medium, or another formula. Do not share mascara, eyeliner, lip products, or applicators, and avoid applying makeup to irritated or infected skin. If an item causes burning, itching, swelling, or a rash, stop using it and consider professional medical advice if symptoms persist.
Storage and contamination checks
Keep makeup closed between uses and store it in a cool, dry place rather than in direct sun, a hot car, or a humid bathroom. Wipe the neck of bottles and jars so residue does not prevent a seal. Wash reusable brushes and tools regularly; the makeup tool care and replacement checklist can help you pair product checks with brush maintenance. Pump packaging generally limits repeated contact, but it still needs a clean exterior and a secure cap.
Cadence and checkpoints
A quarterly review is practical for most makeup collections. Choose four recurring points in the year, such as the beginning of each season, and spend 15–20 minutes checking the bag, drawers, and travel kit. A shorter monthly glance is useful for mascara, liquid eyeliner, and products used frequently.
- Gather everything. Include products in handbags, bathroom drawers, event kits, and travel pouches.
- Check the record. Find the opening date, PAO symbol, printed date, or purchase note. Add a label if the item is staying.
- Inspect the formula. Look for separation, drying, clumping, odor, color change, mold, or an unfamiliar texture.
- Clean the outside. Wipe packaging and wash tools according to their material and care instructions.
- Sort into three groups. Keep, monitor, and discard or replace. Do not keep questionable eye products in the “monitor” group.
- Update your replacement list. Note the category and shade before shopping so you replace what you use rather than accumulating duplicates.
For a simple inventory, copy this template into a note or spreadsheet:
Product | Shade | Date opened | PAO/printed date | Storage spot | Condition | Action ________ | _____ | ____________ | _________________ | ____________ | _________ | Keep / Monitor / Replace
Before travel, check liquids, cream products, and rarely used items separately. A compact kit is easier to inspect and less likely to contain forgotten products; use this makeup travel packing checklist when preparing a trip.
How to interpret changes
Not every change means the same thing. A powder may develop a hard surface because oils from skin or a damp tool have transferred onto it; remove the surface only if the product remains odor-free, dry, and otherwise normal, and replace it if uncertainty remains. Liquid foundation can separate after sitting, but a persistent split that does not recombine as intended, a new odor, or a grainy feel is a reason to stop using it. Lip products may show slight surface changes, but a rancid smell or repeated sweating suggests replacement.
Packaging damage matters too. A cracked compact can expose powder to moisture and debris, while a loose cap can allow a liquid product to dry or become contaminated. If a product was dropped into dirty water, shared during an illness, used on broken skin, or exposed to unusual heat, treat that event as a reason for an earlier review. When a label and the product’s condition disagree, use the more cautious option.
Replacement does not have to mean buying an identical item immediately. If you rarely use a shade, remove it from the active collection. For frequently used products, compare the formula with your current needs before replacing it. Skin changes, seasonal dryness, or a new preference may make your former foundation shade and undertone match less useful, even if the product has not reached its planned replacement point.
When to revisit
Return to this checklist at least once each quarter, and revisit it sooner after an illness, a move, a hot-weather trip, a product spill, or any eye irritation. Review mascara and liquid eyeliner monthly if they are used often. Check all products before applying makeup for a wedding, performance, photo session, or other important event so there is time to replace anything questionable and test a new item safely.
At the end of each review, keep only products you can identify, date, and use comfortably. Photographing the PAO symbol or adding an opening date to a calendar can make the next check faster. If you are introducing a replacement, patch test it as appropriate rather than opening several new products at once; the guide to patch testing makeup and introducing products safely provides a more deliberate process.
The goal is not to discard makeup on an arbitrary schedule. It is to maintain a manageable routine, notice meaningful changes early, and make informed replacement decisions. A short, repeatable inventory review keeps your makeup tools and products ready for everyday use without relying on memory alone.
