The largest drawback with utilizing expired sunscreen is that it gained’t present the acknowledged SPF, or solar safety issue, which may lead to sunburns and enhance your threat for solar harm and skin cancer, dermatologist Dr. Joyce Park — founding father of Skin Refinery and content material creator @teawithmd — informed HuffPost.

How To Verify If Sunscreen Is Expired
Most sunscreens have a shelf lifetime of about three years. The expiration date can sometimes be discovered on the highest fringe of a tube, the underside of a bottle or aerosol can, or someplace on the label.
However not each sunscreen can have an expiration date printed on it. If there’s no date, it “ought to be thought-about expired three years after buy,” per the Food and Drug Administration.
Take into account writing the month and year of purchase in everlasting marker on the sunscreen container while you purchase it. That approach, you don’t have to depend on your reminiscence to know when it expires. This additionally is useful if the expiration date on the label will get smudged and laborious to learn over time.
Different indicators a sunscreen has gone unhealthy embrace a cool odor (which can be a signal of bacterial contamination), clumping, separation or “vital pilling when utilized on the pores and skin,” Hu stated. For those who discover any of those modifications, it’s time to throw it away.
Opening the sunscreen should not speed up the expiration process, in keeping with Shopper Stories testing. So long as it’s been saved at room temperature, “it should keep its degree of safety whether it is nonetheless in that three-year window,” Susan Sales space — the challenge chief for sunscreen testing at Shopper Stories — informed the publication. “We’ve got retested sunscreen samples from earlier years’ testing after storing them in our lab and located no variations in efficiency.”
That stated, even when the SPF stays intact, “handling of the sunscreen container with dirty hands, or frequent opening and shutting can expose the sunscreen to micro organism,” dermatologist Erin Gilbert informed Attract.
Sunscreen that’s been uncovered to warmth or daylight “will doubtless result in sooner product degradation,” Hu stated. So if it’s been sitting in your car, for instance, you’ll in all probability have to toss it sooner.
For those who’re headed outdoor, keep in mind to maintain sunscreen within the shade, inside a bag or wrapped in a towel. In your house, one of the best place to retailer sunscreen is an space that’s cool, dry and darkish. So a moist toilet in all probability isn’t the best spot — however your bed room or a closet may be.
