10 Things You Should Know Before Choosing Sunscreen Product
There are 10 things you should know before choosing a
1. Get rid of your old sunscreen! Generally, sunscreen has 3
years shelf life. But, it depends on the condition you keep
your sunscreen at. Your sunscreen should be fine to use
until the expiration date, unless it hasn’t been exposed
to extreme heat conditions. If it happens,
you’d better get a new one!
2. SPF (Sun Protection Factor) tells you how much sunscreen
will protect you from sun rays. Higher SPF means greater
sunburn protection for your skin.
3. The “waterproof” term on sunscreen labels, now has been
replaced by “water-resistant”. The terms “water-resistant”
state how long the sunscreens provide protection after
water exposure or sweating. And of course, you need
to reapply sunscreen for every 40 or 80 minutes.
4. Always look for a broad spectrum sunscreen product.
It will protect your skin towards ultraviolet A (UVA)
and ultraviolet B (UVB) rays. UVA rays could
prematurely your skin age, and enhance the appearance
of wrinkle on your skin. And UVB rays are the
main cause of sunburn.
5. If you want your skin all exposed to sunlight, use
an ounce or as much as a shot glass of sunscreen.
And don’t forget to reapply at least every 2 hours,
even if you don’t sweat or doing water activities.
6. Never buy a product that combines sunscreen and
insect repellent functions. You need to reapply
sunscreen frequently, and insect repellents should not.
The best way to get both functions are
buy separate products, and apply them separately.
7. Lotion sunscreen is the best choice compared to
spray sunscreen. It might be easier to apply sunscreen
with just one spray. But, its harder to make sure that
all your skin has covered perfectly. Other than that,
spray sunscreen could be harmful for those
who has respiratory issues.
8. Sunscreen products are also available in various form,
including powder. These kind of sunscreen is super
easy to inhale, so you better avoid using it.
9. Don’t forget to apply sunscreen before you go out in
the sun. Make sure that you don’t miss any spots.
It’s important to provide your kid best protection under
the sun, because skin burns during childhood can
especially raise the risk of skin cancer later in life.
10. There are some controversial sunscreen ingredients,
such as oxybenzone, retinoids, and nanoparticles.
American Academy of Dermatology stated that those
ingredients doesn’t pose a health risk.
But, too much sun exposure does.
