Is yourbottle older than the pandemic? It's probably time to toss it. This summer (and every single day the sun shines) it's important to slather on the , especially if you're going to spend more time outdoors than you did last year.
But before heading to the park, pool, beach or backyard this summer, make sure your sunscreen is actually going to work for you. Yes, sunscreen can expire and when it does, it's not as protective.
When does sunscreen expire?
The Food and Drug Administration mandates that all sunscreens maintain their full strength for three years -- so, if you have leftover sunscreen at the end of the summer, you should be able to safely use it for two more summers.

- Consistency: If the sunscreen is very watery or chunky, it may be expired.
- Color: If it appears an unusual shade, it's probably expired.
- Smell: If it smells different than it did when you bought it (or smells weird in general), it may be expired.
Can you use expired sunscreen?
Using expired sunscreen won't hurt you directly -- as in, it won't do anything to your skin -- but it could set you up for a gnarly sunburn. And, as you already know, sunburns indicate unprotected sun exposure, which is directly related to yourand premature aging.
The expiration date is there for a reason: to let you know if that sunscreen is still effective. It's always a good idea to buy a new bottle of sunscreen if yours is expired. And if you're into tanning under the sun, try a.
