Your sunscreen has expired. Should you still use it?

Sunscreen is expensive so do we really need to toss it if it’s expired? 

Not necessarily, according to dermatologist Dr. Karen Burke. Most sunscreens last for a year or two, and will last another six months past that date if they’ve been stored correctly. Sunscreen that has been exposed to heat or light will break down faster. To get the most out of your bottle, be sure not to leave it in a hot car or in direct sunlight. If you squeeze some sunscreen out and it smells odd or looks separated, toss that bottle and get a new one.
