And to be totally safe (unless you’re positive your old sunscreen sat in a temperature-controlled drawer for the last year), your best bet is to buy a new tube this summer. Sorry, but heat and humidity can cause the formula to separate and destabilize, rendering it ineffective at protecting you against sunburns, skin damage and, you know, skin cancer. Of course, if you’ve kept your tube of sunscreen in, say, the glove box of your hot-as-hell car for three years straight, letting it cook and warp under the harsh summer rays, you need to toss it in the trash, pronto. If it does and you’ve surpassed it, throw that sucker out - some formulas really aren’t effective after their expiration date due to specific ingredient formulations, so there’s no guarantee you’ll get full (or any) protection if you use an expired formula before heading into the sun. But before you slather it on, check to make sure it doesn’t have an expiration date. Hence, this means that the sunscreen will last for 12 months once opened.

The open jar symbol will have a number and an ‘M’ on it which refers to how long the sunscreen will last once opened.
