the problem? Most of us do not use sunscreen liberally during the colder months, although we should do so, which means that the bottle you reach for has been sitting in your cabinet for at least a year.
So, can you still use it? it depends. Here, dermatologists decipher your expiration date on your sunscreen bottle.
Does sunscreen expire?
As well as the items in your cabinet medicine cabinet, the sunscreen will have an expiration date, then the old bottle will not be so good for you. While you may want to believe that the “used” and “best” dates printed on your favorite bottles and sprays are just a suggestion, it is not.
“Sunscreen actually expires and always has an expiration date printed somewhere on the packaging,” said Dermatologist Dr. Chicago, who is certified by the Chicago Board of Cosmetic Surgery and Dermatologist. Dr. Lauren Fine said. “Expired sunscreen will not work and increase the chance of sunburn.” Not only is a burn painful, it can also increase the risk of skin cancer – the most common cancer in the United States. Rule: Do not use sunscreen after the listed expiration date.
How to tell if your sunscreen is out of date?
Here’s the problem: Not every sunscreen has an expiration date, but the Food and Administration Administration requires that the product retain its original strength for three years. So if you buy a bottle and do not see an expiration date, the American Academy of Dermatology recommends that you write the date you bought the sunscreen on the bottle so you know exactly when to remove it.
One more thing to note: if you bring your sunscreen to the beach and it sits in the heat and ultraviolet rays, the boards will certify that it will get worse before the expiration date. Dr. Lance Brown notes. New York City.
Be sure to peel off your sunscreen and see if there is any change in its formula. If it starts to look, smell or have fun, throw it away. AAD says your sunscreen should not change color or consistency.
The most important thing to remember is that if you want complete UVA / UVB protection you should apply adequate sunscreen. Dr. Fine says that you should use a shotgun the size of a glass to cover exposed parts of your body and reapply it every two hours. This means that you do not have to worry about expiration dates if you apply your sunscreen properly. A 4 ounce bottle should technically only last for four applications.
Conclusion: If your sunscreen has expired or changed color, odor or consistency, throw it away and buy a new one. Thank you for your skin!
