When summer rolls around, it’s time for the annual ritual of digging through your beach bag to find your sunscreen. As you pull out last year’s bottles of sunscreen, you might ask yourself, “Does sunscreen expire?”
In this article, we’ll answer your questions about sunscreens and expiration dates so you can keep your family safe and comfortable this summer during every adventure! Let’s get straight to the big question.
Does Sunscreen Expire?
Does sunscreen expire? The short answer is yes. But it’s not as simple as that.
If sunscreen expires, it makes sense that all sunscreen bottles would have an expiration date. But some do and some don’t! That’s confusing.
Let us clarify things.
Understanding Sunscreen Expiration Dates
Sometimes figuring out when your sunscreen expires is as simple as looking at the bottle. If it lists an expiration date, it’s easy — you should throw your sunscreen out if it’s past the date on the bottle.
But what are you supposed to do when there’s no expiration date anywhere to be found?
The FDA (the U.S. Food and Drug Administration) requires that all sunscreens list an expiration date on the bottle unless that sunscreen has a shelf life of at least three years.
If your sunscreen doesn’t have an expiration date on the bottle, you can assume it’s expiration date is three years from the time you bought it (this is where actually remembering when you bought the sunscreen comes into play!).
Other than time, what makes a sunscreen expire? Exposure to heat and sun.
So, if your sunscreen is in and out of the sun (what sunscreen isn’t?) or stored in the garage, it may go bad sooner than the expiration date.
That brings us to our next point. If you can’t remember when you bought your sunscreen or you’re wondering if it’s gone bad early, how can you know?
There are a few simple ways to tell if your sunscreen has expired.
How To Tell If Your Sunscreen Has Expired
Both chemical and mineral sunblocks can expire, though mineral sunscreens tend to remain more stable than their chemical counterparts.
(If you aren’t familiar with the differences between mineral and chemical sunscreen, check out our explanation here.)
As time goes by, chemical sunscreens with active ingredients like oxybenzone go through a process called oxidation (a chemical reaction that changes a substance). Mineral sunscreens with active ingredients of either zinc oxide or titanium dioxide degrade over time.
How can you do a quick check to tell if your sunscreen is still good or not? With both mineral and chemical sunscreens, you may notice a change in color, smell, or texture.
When mineral sunscreens have been around too long, they tend to separate (you’ll notice a runny liquid) or become grainy.
Chemical sunscreens can change in texture, too, but you may also notice that they have a yellow tint or smell unusual.
Now that you know how to understand sunscreen expiration dates and even decide for yourself if it’s time to replace your old sunscreen, you’re probably wondering what the big deal is.
Is it really that bad to use an expired sunscreen when you’re in a pinch?
What’s The Risk Of Using Expired Sunscreen?
If your only options are using an expired sunscreen or no sunscreen at all, giving the expired sunscreen a go is the better choice.
That being said, always try to keep your sunscreen up to date because there are a few reasons why using expired sunscreen is a bad deal.
1) Expired Sunscreen May Not Be Effective
Checking on sunscreen expiration is pretty important because a no-good sunscreen will leave you susceptible to sun-related risks. An expired sunscreen becomes less effective at warding off UVA and UVB rays.
This means you’re at risk for sunburn, premature aging, skin damage, and skin cancer — all the issues that come along with too much sun exposure.
Plus, even if the active ingredients in your expired sunscreen are still effective, it may simply be that it won’t spread evenly on your skin to provide you with appropriate protection.
Either way, expired sunscreen is not worth the risk.
If you accidentally spent a day in the sun with an expired sunscreen that did you no good, care for your skin after the fact with Babo Botanicals’s After Sun Soothing Hydrating Aloe Gel.
Apply this soothing, cooling, and quick-absorbing aloe vera gel to your face or body — wherever your sun-kissed skin needs some relief!
In addition to aloe leaf juice, our gel contains green tea, witch hazel, arnica, and eucalyptus oil. All that goodness for your skin and absolutely no gluten, dairy, soy, parabens, and phthalates.
2) Expired Sunscreen Can Contain Bacteria
The longer sunscreen sits around and the more you open it, shut it, and take it on all your adventures, the more chance there is for bacteria to grow. Bacteria isn’t good for anyone’s skin and can cause irritation or a breakout.
But if you have especially sensitive skin, you already know that you need to be extra careful with what you put on it. You’ll want to think twice before slathering on a questionable sunscreen.
Speaking of you sensitive skin folks and sun protection, you may find that even current chemical sunscreens irritate your delicate skin.
But a hypoallergenic mineral sunscreen is especially important if you have easily irritated skin. Opt for a non-nano zinc oxide sunscreen, like Babo Botanicals’s Clear Zinc Sunscreen Lotion SPF 30. Our unique, clear formula is made with skin-soothing certified organic oils.
Now that you have the scoop about sunscreens expiring, what steps can you take to prolong their shelf life?
How To Get The Most Out Of Your Sunscreen
When it comes to getting the most out of your sunscreen and making it last as long as possible, there are just a few things to keep in mind.
1) Keep Sunscreen At Room Temperature
As we mentioned earlier, sunscreen goes bad more quickly if it’s exposed to heat. Obviously, your sunscreen should come with you to the pool or the beach — anytime you’re out in the sun.
So, some heat exposure is inevitable!
But while you’re out and about, rather than leaving your sunscreen in the sun, keep it inside your beach bag, backpack, or purse. If you can leave it in the shade, even better!
To protect it from the heat in-between outings, store your sunscreen inside the house instead of leaving it in the car or on a shelf in the garage.
2) Write The Date On The Bottle
If you notice that the new bottle of sunscreen you just bought doesn’t have an expiration date, it’s a good idea to grab a permanent marker and write the date you bought the sunscreen right there on the bottle.
That way, you’ll know when three years have passed, meaning it’s time to do away with that bottle and buy a new one. This is most helpful with bottles that you find in the black hole of your closet.
Because, let’s be honest, if your sunscreen lasts you three years, you’re probably not applying enough. That brings us to our final point.
3) Apply Lots Of Sunscreen
Like we said, if a bottle lasts you three years, that either means it has been lost in the bottom of your bag or that you’re not using enough sunscreen every time you apply.
A little dab of sunscreen here and there is not enough. Apply it generously all over your body to get the best protection!
If you’re applying mineral sunscreen sparingly because of how it tends to leave you one shade whiter all over, fear no more. At Babo Botanicals, we’ve got you covered.
Our mineral sunscreen, like our Sheer Zinc Continuous Spray Sunscreen, goes on clear. No more white streaks!
Protect Your Family From The Sun
Keeping your family safe and happy during summer play days involves choosing a safe sunscreen, applying it all over, and also checking to make sure it hasn’t expired!
Don’t forget to read expiration dates at the beginning of each summer and throw out what is expired. If in doubt, buy new sunscreen for the whole family: Baby Skin Mineral Sunscreen for the little ones and Clear Zinc Sunscreen Lotion for the rest of you.
