In fact, many sunscreen companies don't put expiration dates on their products, but others like Coppertone do.
"If you're putting on sunscreen, you think you may be safe from the sun, but you may not be," says East Meadow resident Brittany Kalman, "so why not put the expiration date on to keep you safe?"
That's the idea that New York Assemblyman Harvey Weisenberg has been fighting for. For 19 years he has been trying to get a bill passed that would require companies that manufacture sunscreen products to put expiration dates
The bill has passed the Assembly unanimously several times, but the Senate hasn't taken it up. Weisenberg says it all comes down to politics
"There are a lot of things happening in Albany where money is more important than people, but I'm not talking about money," said Weisenberg.
Colette Coyne started a melanoma awareness campaign based on Long Island after her daughter died of the disease in 1998. She says there is really no good reason why sunscreen products don't have expiration dates.
"Let's face it, if a store doesn't sell it this season, they're not going to throw it away, it will go into storage and come back next season," says Coyne.
