Sunscreens are designed to remain at original strength for up to three years. This means that you can use leftover sunscreen from one year to the next. Some sunscreens include an expiration date — a date indicating when they're no longer effective. Discard sunscreen that is past its expiration date. If you buy sunscreen that doesn't have an expiration date, write the date of purchase on the bottle. Also, discard sunscreen that is more than 3 years old, has been exposed to high temperatures or has obvious changes in color or consistency. And if your sunscreen doesn’t have an expiration date, you probably shouldn’t take the chance that it’s still good. (Next time, use a permanent marker to write the date you purchased it on the bottle.) Ditch any old sunscreen that smells funny or has changed color, even if it hasn't expired. 1 Using expired sunscreen isn't as noticeable as drinking expired milk, but it can drastically reduce the sun protection you're getting. 2  It's best to discard expired bottles once they have reached the expiration date. 3  The downsides of using expired sunscreen are too high. The Answer: All sunscreens have an expiration date printed on the bottle. Typically they last a year or two, and most are good for three years. The safest bet, naturally, is to ditch old product and replace it. But in a pinch, here’s a secret: Sunscreen is still good for six months beyond its expiration date. 1 Sunscreen is designed to remain stable for three years. 2  For those without an expiration date, it's best to throw them out within two years after the purchase. 3  Using expired sunscreen isn't as noticeable as drinking expired milk, but it can drastically reduce the sun protection you're getting. 1 The downsides of using expired sunscreen are too high. 2  Too much exposure to the sun could result in sunburns, premature aging, skin damage, and skin cancer. 3  Long term exposure to the sun without proper protection can be extremely dangerous, it's not worth the chance.
