How the heck are you supposed to use sunscreen right if everyone has a different opinion about it?!
Apply it before you go to the beach. No, you can slather it on once you get there.
Use it every day, even if you’re not going to the beach. No wait, you won’t get your vitamin D fix that way.
Argh! What’s a girl to do to avoid wrinkles, cancer and all the other crap the sun causes.

Sunscreen Myth #1: All Sunscreens Protect From Both UVA And UVB Rays
You’d think this would be a given. How can you sell a sunscreen that protects only from one type of UV rays? And yet, that’s what happened for years…
I admit it’s rare these days, but you can still come across a sunscreen that protects only from UVB rays if you don’t check those labels carefully. How do brands get away with this?
Easy. SPF, or sun protection factor, only measures sunscreen protection from UVB rays. If it blocks 97% of UVB rays, it can be labelled SPF30 even if it offers no protection at all from UVA rays!
That’s not good enough. You need protection from BOTH UVA and UVB rays. Here’s what to look out for on the label:
- “Broad spectrum”: Most Western sunscreens use this term to let you know they provide protection from both UVA and UVB rays.
- Plus sign: Asian sunscreens use the PA system. The more + signs next to the PA letters, the more protection from UVA rays the sunscreen provides.
- UVA filters: You can always check the ingredient list to make sure it contains an UVA filter. They are zinc oxide, titanium dioxide, avobenzone, mexoryl, and tinosorb.
Sunscreen Myth #2: Layering Sunscreens Adds SPF
I wish! Wouldn’t it be great if you could use a moisturizer with SPF 15, a sunscreen with SPF 50 and a foundation with SPF 20 and get an SPF of 85?
Sadly, it doesn’t work out that way. Adding more products with SPF doesn’t increase sun protection. You still only get the protection of the highest SPF you’ve applied. In this case, 50.

Sunscreen Myth #3: I Can’t Get A Tan If I Use A High SPF Sunscreen
First of all, you shouldn’t get a tan anyway. A tan is a sign of sun damage. Period.
Besides, you’ll tan even with sunscreen. Truth bomb: no sunscreen blocks 100% of UV rays. SPF30 blocks only 97%. Even SPF100 blocks only 99%.
And that if you apply the required amount (around a glass shot for the whole body) and reapply it every two hours…
In real life, that means you’ll still get a tan even if you wear sunscreen. You’ll just develop it way more slowly (and prevent most of the damage it always brings).

Sunscreen Myth #4: Your Old Sunscreen Bottle Is Still Effective
By old, I mean more than one year old. You know last year’s half used bottle you’ve kept for the upcoming summer. It won’t do.
Sunscreens start losing effectiveness after one year. Even sooner than that if you’ve kept them under or near the heat (like in your car). Don’t risk it.

Sunscreen Myth #5: It’s Enough To Apply Sunscreen Once A Day
Maybe if it’s a really, really, really gloomy day and you’re spending most of it inside.
Most days, sunscreen reapplication is a necessary evil. Here’s why:
UV filters get deactivated by sunlight. The longer they’re exposed to UV rays, the sooner they lose their effectiveness and leave you unprotected.
Not to mention, you’ll brush sunscreen off your skin when you swim, sweat, dry yourself off with a towel…
Half of the sunscreen you’ve put on half an hour ago has already gone. Do your skin a favour and reapply it often.
Sunscreen Myth #6: You Don’t Need Sunscreen If It’s Cloudy
Sorry to be the bearer of bad news, but those UVA rays are sneaky. They easily penetrate even through the darkest of clouds and hit your face, causing all sorts of damage.
Just because you can’t see the sun, it doesn’t mean it’s not hurting you.
Sunscreen Myth #7: You Don’t Need To Wear Sunscreen If You Spend Most Of Your Day Indoors
It makes sense, does it? If the sun can’t get you inside, why bother with sunscreen?
Because the sun CAN get you inside my friend. And it WILL.
Here’s the deal. In the past, sunscreens only protected your skin from UVB rays. Those can’t penetrate glass, so if you were inside, you didn’t need to use sunscreen.
UVA rays are another matter entirely. These pesky rays CAN penetrate through glass so if you’re inside, especially if you live or work in a place with big windows, you’re not safe from them.
It doesn’t matter if you’re outside or inside, if you want to keep your skin safe from UV harm, you need to wear your sunscreen from the moment the sun comes up to the moment the sun comes down.

Sunscreen Myth #8: It’s Best To Apply Sunscreen When You Get To The Beach
And what will keep your skin safe while you get there? Hope and prayers?
I’ve told ya, UVA rays can penetrate glass. That means car windows, too.
Besides, sunscreen should always be applied at least 20 minutes BEFORE you head out the door. That gives it time to form an even shield against UV rays.
Don’t fool yourself you’ll only be out for 5 minutes anyway. 5 minutes here and 5 minutes there build up to A LOT of damage!
Sunscreen Myth #9: If You Wear Sunscreen, You Won’t Get Enough Vitamin D
Sunscreen is a must. It keeps you safe from wrinkles, dark spots and cancer.
Vitamin D is a must, too. It prevents rickets, keeps your teeth and bone healthy and does plenty more good things for your body.
Few foods have vitamin D. But when you expose your skin to the sun, your body produces vitamin D in spades. Unless you wear sunscreen. That blocks UV rays and, as a result, vitamin D production.
BUT, not completely!
Even SPF 100 lets 1% of UV rays through (no, a sunscreen that blocks ALL UV rays hasn’t been invented, yet).
So, you can still wear sunscreen and get your vitamin D fix. Win win.
P.S. If you have a severe vitamin D deficiency, consult a doctor for supplements. The sun should always be your LAST resort for your vitamin D fix.
Sunscreen Myth #10: If You Have Dark Skin, You Don’t Need Sunscreen
It’s true dark skin produces more melanin than fair skin. That makes it less likely to burn.
BUT, you can still burn. AND you’ll still get wrinkles and dark spots. AND you’re more likely to die from skin cancer than people with a fairer complexion.
You see, if you know you’re at risk, you wear sunscreen. But if you think you can do without, you’ll take more risks with the sun.
You’ll also be less likely to go for regular screenings for cancer (why go if you think it can’t happen to you?). When you finally realise there’s something wrong, it may already be too late.
Don’t gamble with your life. Wear sunscreen every day.
Sunscreen Myth #11: If You Already Have A “Base Tan” You Don’t Need Sunscreen
First things first: there’s no such thing as a healthy tan. A tan, whether it’s from sun exposure or a tanning bed, is a sign that your skin is damaged. Y
our skin gets darker because it’s trying to defend itself from UV rays – and telling you to get the heck out of there, now. If you keep on tanning, you’re just putting yourself at risk of sun damage and skin cancer. Don’t do it.
But even if you’re already tanned, don’t fool yourself that base tan will give you some adequate sun protection. Your skin is already in trouble. Don’t make it 10x worse. Wear your sunscreen, base tan or no base tan.

Sunscreen Myth #12: If You Stay In The Shade, You Don’t Need Sunscreen
I totally agree that you should seek the shade whenever possible. Or wear a hat. Or use an umbrella, even. But that doesn’t exonerate you from wearing sunscreen.
The harsh truth is that shades don’t completely block all the sun rays. Translation: if you don’t wear sunscreen in the shade, you’re still at risk of sun damage. Ugh.
Sunscreen Myth #13: Sunscreen Blocks Out All UV Rays
If only! No sunscreen, not even those with SPF 100, can block out ALL UV rays. Some sunscreen can block up to 99% but a few sneaky rays still get through.
That’s cool. If only a tiny amount of rays get through, you can neutralise them with an antioxidant-rich serum. But you wouldn’t do that if you were convinced your sunscreen is enough, right?
Choose one with a high SPF and make sure it offers broad spectrum protection (check for the word “broad-spectrum” on the packaging).
