Does Sunscreen Expire?

Yes. Sunscreen expires, and bottles without a date should be treated as expired three years after purchase if stored properly.

Direct answer

Yes, sunscreen expires. Use the printed expiration date when there is one. If a sunscreen has no expiration date, treat it as expired three years after purchase, assuming it was stored in a cool, dry place. Replace it sooner if it was left in heat, direct sun, or a hot car, or if the color, smell, texture, or consistency changes.

printed date first; no date = three years from purchase if stored properly

Expired sunscreen is not worth rationing

Sunscreen only helps when the formula still works and you apply enough of it. If a bottle is expired or questionable, using less to make it last is the wrong tradeoff. Replace it and use the amount recommended on the label.

How to manage sunscreen bottles

2Write the purchase date on bottles that do not show an expiration date.
3Store sunscreen away from heat and direct sun when not in use.
4Throw out bottles that smell odd, separate, look grainy, or feel watery or clumpy.
5Replace opened bottles you cannot date confidently.

FAQ

Can I use sunscreen after the expiration date?

Do not rely on expired sunscreen for real sun protection. Replace it if the date has passed, if you do not know when you bought it, or if the texture, color, or smell has changed.

How long does sunscreen last if there is no date?

If there is no expiration date, treat it as expired three years after purchase, assuming it was stored properly. Write the purchase date on the bottle when you buy it.

Does heat make sunscreen expire faster?

Heat and direct sun can degrade sunscreen faster. Do not leave bottles in hot cars, direct sun, or beach bags for long storage if you want the product to stay reliable.
