The problem? Many of us don바카라 게임 웹사이트t apply sunscreen liberally during the colder months, even though we should, meaning the bottle you바카라 게임 웹사이트re reaching for was probably sitting in your cabinet for at least a year.

Does sunscreen expire?
Just like the items in your medicine cabinet, sunscreen has an expiration date, so that old bottle may not do you much good. Even though you may want to believe that the 바카라 게임 웹사이트use-by바카라 게임 웹사이트 and 바카라 게임 웹사이트best-by바카라 게임 웹사이트 dates stamped on your favorite bottles and sprays are just a suggestion, that바카라 게임 웹사이트s simply not the case.
"Sunscreen does indeed expire and will always have an expiration date printed somewhere on the packaging," said , a board-certified dermatologist at Chicago Cosmetic Surgery and Dermatology in Chicago. "A sunscreen that바카라 게임 웹사이트s expired will not work as well and increases your chance of getting a sunburn."

The rule of thumb is: Don바카라 게임 웹사이트t use sunscreen past its listed expiration date.
How to tell if your sunscreen is expired
Here바카라 게임 웹사이트s the problem: Not all sunscreens include an expiration date on them, but the Food and Drug Administration requires that the product retain its original strength for three years. So if you buy a bottle and don바카라 게임 웹사이트t see an expiration date listed, the American Academy of Dermatology recommends writing the date you bought the sunscreen on the bottle, so you know exactly when to get rid of it.
Another thing worth noting: If you bring your sunscreen along to the beach, and it sits in the heat and direct ultraviolet light, it may actually go bad before the expiration date, notes , board-certified surgical and cosmetic dermatologist in New York City.
Keep an eye out for any changes in the sunscreen. If it starts to look, smell or feel funky, toss it. Your sunscreen shouldn바카라 게임 웹사이트t change in color or consistency, the AAD says.
The most important thing to remember is that you need to apply enough sunscreen if you want full UVA/UVB protection. Aim to use a shot glass-sized amount to cover exposed parts of your body and reapply it every two hours, says Dr. Fine. That means you shouldn바카라 게임 웹사이트t even have to worry about expiration dates if you바카라 게임 웹사이트re applying your sunscreen properly. A 4-ounce bottle should technically only last for four applications.
Bottom line: If your sunscreen has passed its expiration date or has changed in color, smell or consistency, throw it out and purchase a new one. Your skin will thank you!
