I was so reckless with sunscreen. Earlier than my mid 20s, I solely used it on the seashore (learn: by no means. Going to the seashore is my concept of hell – I do know, weirdo). The few instances I used to be dragged there, I’d begrudgingly put sunscreen on, after which go away the bottle mendacity wherever. Within the automobile, on the sand beneath the scorching solar, on my mattress… Who cared?
Effectively, I want I did care. The way in which you retailer sunscreen issues. Do it improper, and it loses all its effectiveness. The worst half is that you simply typically don’t realise there’s one thing improper with it till you get a nasty sunburn. Ouch!
And right here’s the worst half: as soon as it’s degraded, there’s no going again. You may’t simply shake the bottle or cool it down and hope it’ll work once more. Sunscreen isn’t a telephone. It doesn’t bounce again after overheating. The UV filters inside break down, and as soon as they’re damaged, that SPF quantity on the label turns into meaningless. So, the right way to retailer your sunscreen so it doesn’t go unhealthy on you?
3 Issues To Hold Your Sunscreen Away From
You must all the time hold your sunscreen away from:
- Direct daylight
- Warmth
- Humidity
All this stuff degrade and weaken sunscreen till it turns into fully ineffective. Why does this occur? As a result of sunscreen formulation depend on very particular chemical buildings to work. Substances like avobenzone or oxybenzone (in chemical sunscreens) and zinc oxide or titanium dioxide (in mineral ones) can degrade beneath warmth or UV publicity, particularly when suspended in unstable emulsions.

The place Not To Retailer Sunscreen:
1. Don’t Retailer Sunscreen In The Rest room
I used to maintain all my skincare merchandise within the lavatory, as a result of it’s SO handy. Too unhealthy it’s lethal for all of your lotions and potions (sunscreen included). Right here’s the deal: the temperature within the lavatory adjustments on a regular basis. Take into consideration all these heat showers you’re taking. They make the temperature stand up, after which it goes again down, after which again up once more.
All that heat and humidity could make your fave merchandise flip mouldy and go unhealthy sooner. To not point out, mould loves moisture. And nobody desires to be rubbing mould spores onto their face with what’s alleged to be a protecting layer. Even when your sunscreen seems to be nice, microscopic progress or chemical breakdown could possibly be taking place with none seen indicators.
2. Don’t Retailer Sunscreen In The Automobile
It’s handy to retailer your sunscreen within the automobile, isn’t it? That approach, you might have it with you in every single place you go. However, if it’s a sizzling day and also you park your automobile beneath direct daylight, you’re just about storing your sunscreen into an oven.
If the day is absolutely, actually sizzling, the automobile will flip into an oven no matter the place you park it. Do carry your sunscreen with you, however watch out to not “cook dinner” it, otherwise you’ll must throw it away!
For context: automobile interiors can simply attain 50-70°C (122-158°F) in summer season. That’s hotter than most skincare merchandise are designed to tolerate. Some formulation can separate, emulsions can curdle, and actives can fully denature. In case your sunscreen smells funky, has modified texture, or seems to be separated? Toss it.
3. Don’t Retailer Sunscreen Close to A Window
I used to let my sunscreen lie round wherever, together with my mattress and my desk, which had been typically beneath direct daylight. Mainly, they had been the hottest spots in the home. Not good, Gio!
After all, this isn’t as unhealthy as storing sunscreen within the automobile because the temperature gained’t rise as a lot. However, if you need your sunscreen to work its finest and final that little bit longer, keep away from anyplace that’s beneath direct daylight.
Yet one more factor: daylight not solely heats up the bottle, however UV rays also can penetrate packaging (particularly clear or evenly tinted ones) and degrade the method inside. Until your sunscreen is available in an opaque, UV-blocking bottle, it’s higher off in a drawer.

The place Ought to You Retailer Sunscreen?
All the time retailer your sunscreen someplace cool, darkish and dry. I hold mine in a drawer in my bed room. It suits the invoice effectively, particularly in London, when the climate not often will get that sizzling.
Nonetheless, I all the time put a bag of silica gels in there, simply to maintain the drawer dry. Silica gels are nice at absorbing the surplus moisture attributable to humidity that will make your sunscreen (and all the pieces else) go unhealthy quicker.
For those who journey with sunscreen, think about using an insulated pouch or a cooler bag to forestall publicity to warmth. A travel-friendly sunscreen stick or mini-size tube is simpler to stash in a bag with out leaving it within the solar.
And all the time, all the time verify the expiration date. Even when saved completely, sunscreen solely lasts so lengthy. A great rule of thumb? Substitute it each 12 months, and sooner if it’s been sitting in warmth or humidity.
What Occurs If You Use Expired Sunscreen?
Mainly? You’re rolling the cube along with your face. The SPF quantity may nonetheless be printed on the bottle, however the safety? Gone. You’re out right here pondering you’re lined, in the meantime your pores and skin is roasting like a hen. Good day, sunburn.
And it’s not simply the burn. Lengthy-term? We’re speaking wrinkles, pigmentation, even pores and skin most cancers dangers creeping up as a result of your sunscreen simply gave up midway by way of your day. Oh, and if the method’s gone bizarre? Prepare for enjoyable little surprises like breakouts, stinging, or a rash. Cute.
How To Inform If Your Sunscreen’s Gone Dangerous
Right here’s the vibe verify:
- Seems separated, gloopy, watery, or simply… off?
- Smells funky, like bitter milk or a highschool chemistry lab?
- Shade seems to be darker or yellow-ish?
- Doesn’t mix proper or leaves a bizarre movie in your pores and skin?
Toss it. Don’t overthink it. If one thing feels off, it in all probability is off. Sunscreen’s not the place to be sentimental.

The Backside Line
Overlook about loos and vehicles. Your sunscreen is just pretty much as good as the place you retailer it. You should buy the perfect method available on the market, but when it’s been baking in your dashboard or sweating it out in your bathe, it gained’t defend you. Interval. Deal with your sunscreen just like the high-performance product it’s: retailer it correctly, substitute it recurrently, and your pores and skin will thanks in ten years.
