Hi thank you. Glad i found this forum before I went on a summer beach vacation
re: Sunblock/Sunscreen expirations
TAMPA - Attorney Sarah Younger spends most of her days in an office in downtown Tampa. But as a Florida child, she grew up outside in the sun. “I used to go to the beach all the time," she said.
And she admits she would often get burned. "I thought that I would never get skin cancer that young. I thought that’s something you get when you're older, when your skin peels a thousand times."
But after doctors diagnosed her mom with melanoma, Sarah started getting her skin checked every six months. "I have freckles everywhere, and this was a very normal freckle and we hesitated taking it off. It came back melanoma.”
Luckily, they caught the cancer early before it had spread. “I believe God was watching over me that day." And now? “I never walk out of the door without sunscreen."
We asked her if she ever bothers to stop and look at ingredients or expiration dates? “To be honest, I've never even thought about it. Never even looked."
But does it matter?
We asked Sarah's doctor, Doctor Panos Vasiloudes, if sunscreen actually expires. "Yes, it does. Everything expires. There’s a lifetime to every chemical and biological agent. There is decomposition."
Doctor Vasiloudes says you should use up a bottle in 2 months. And throw it out if it's older than a year old. But who does that?
Doctor Vasiloudes says, "In general, there's no expiration date on bottles and the manufacturers are not required to do that. Some of the more established companies like Coppertone use a label system."
But if there is no expiration date, how can you tell if sunscreen is no longer effective? Dermatologist Henry Wiley says, "There really isn't a good way of knowing whether sunscreen is expired or not. Some of them might have expiration dates but whether those are valid depends on the conditions on which the sunscreens are stored. Generally speaking, when heat is added to any kind of chemical mix, more reactions occur, so the hotter the environment is, the less time a sunscreen is going to last."
We conducted an unscientific test using old or expired sunscreen versus new sunscreen to see if we could see a difference. We didn't pick on any particular products, just used the old sunscreen my fellow employees offered up.
Hope Scheneider put on old but not expired Banana Boat and a new one with the same SPF 15 and the same ingredients.
Johanna Rodriquez put on Banana Boat SPF 4 old and new.
Robin Mills put on a five year old Panama Jack SPF 15 and a new sunscreen with the same SPF and ingredients.
And Randy Hilgeman put on expired Publix SPF 50 and new Publix SPF 50.
The volunteers put new sunscreen on their right arms and the old sunscreen on their left arms and then sat out in the sun to bake for 45 minutes.
The results? 24 hours later, none of our volunteers saw a difference.
So we did the test again - for an hour and a half this time - and got basically the same results, except for Johanna whose old sunscreen arm was noticeably darker. "And it’s like a different tone -- more of an orange than [the other] one."
So what's the take-away from all this?
Both Doctor Vasiloudes and Doctor Wiley say even if you don’t have sunburn, you could be doing damage you'll see later. Short-wave or UVB rays cause sunburn but long wave or UVA rays go deeper and cause damage that ages us or causes melanomas. So, if a sunscreen is over a year old, or you don't know how old it is, both doctors say throw it out.
Because heat can affect the chemicals in some sunscreens, don't keep it in cars, sports bags or anywhere in a hot garage.
Also, Wiley says, look at active ingredients. “Zinc oxide and titanium oxide are basically inert minerals and as such they don't really deteriorate with time. There are another dozen or so chemicals are approved by the FDA most sunscreens are a combination of those chemicals which can eventually break down.
we have been going thru a spray can a week for the last 2 months.
using the WALMART / EQUATE brand Sport #50 spf and the ingredients are avobenzone, homosalate, octisalate, octocrylene and oxybenzone. NO EXP DATE.
We leave the cans of spray block in our pool bags 24/7 except when we are spraying down.
From now on, once we spray down the cans of block stay in the house.
Will my leftover sunscreen from last year still be effective?
Check to see if your bottle of sunscreen is stamped with an expiration date. If you don't see a date, the rule of thumb is that the active ingredients in sunscreen (like zinc, titanium dioxide and Parsol 1789) should remain stable and effective for about three years, according to David Leffell, M.D., professor of dermatology at Yale School of Medicine. But if it smells funny, feels lumpy or has a bizarro color, dump it. To keep your sunscreenas close to new as possible, store it in a dry spot at room temperature with the lid tightly fastened

I came back from my dermatologist to check out a sun spot on my arm from Aruba...not cancerous (whew)
But I did ask her about expiration and she said that they do expire and typically one should not have any sunscreen left in the bottle for that long to begin with. I use ultimate sport sunblock spray SPF 100 from neutrogena for my body because i'm lazy and shiseido ultimate sun protection face and body lotion SPF 50 for my face.
I've been burned before where I had blisters all over my chest and that scared me to hell so I apply, apply and apply. The idea is that you should use as much as possible before it's supposed to expire - that's the right way.
I'm a big believer in sunblock clothing because I saw it work wonderfully for a friend of my son's in Aruba last year. He's very pale, and had gotten a terribly bad burn the summer before, he had to go to the hospital emergency room for treatment, from a day on the river. He wore sun screen religiously, of course, everytime we say him, we reminded him (he was 18), but he loved his sunblock shirt. He said it even made him feel cooler. He came home sunburn free too. I saw this article about sunblock clothing today, and wanted to share it here.
... So does donning a UPF T-shirt really offer an advantage over slapping on traditional sunblock? According to Dr. Mark, yes. Sun-protective clothing can offer significantly more protection than sunscreen in the sense that "there is no variability -- the only variable for whether the clothing will protect is if you wear it," he says. "With sunblock, you have to be using the correct one, apply the correct amount, reapply frequently, be aware of sweating and swimming and other water issues, and apply it 20 minutes prior to exposure. Most people do not
put enough on and do not put it on early enough before going outside." ...
