Sunscreen – sunblock – SPF 30 – SPF 90 spray, gel, cream oh
my!! All the terminology can get confusing and a bit overwhelming. Now that
school is coming to an end and the weather is heating up, families are spending
more time outdoors. I won’t sit here and tell you tell you that you need to
wear sunscreen and rant about how bad sunburns are for your skin - you already
know the dangers! With thousands of different options out there, browsing the
shelves might involve a lot more thought. Keep reading for tips to keep you
safe in the sun!
Let’s start with the basics. What is the difference between
sunscreen and sunblock? There are two main types of the sun’s rays that can
affect our skin – UVA and UVB. UVB rays reach the top of the skin which creates
a sunburn or a tan. UVA rays go deeper into the skin’s layers. UVA rays can
make your skin more prone to melanoma, the deadliest type of skin cancer. Sunscreen’s
job is to absorb the UV rays. With sunscreen, the harmful rays are absorbed by
the product on the skin. Sunblock has a slightly thinker consistency and stays
longer on the skin. When using sunblock, the UV rays are deflected before your
skin can absorb them. Whether you use sunscreen or sunblock, the product should
be applied 30 minutes before going into the sun and reapplied every 1-2 hours.
Now that we have that sorted out, what about SPF? SPF or sun
protection factor, shows to what degree a product prevents a sunburn. For
protection against both UVA and UVB rays, you want to pick a product that has a
“broad spectrum” of protection. Doubling the SPF value does not mean you get double
the protection. SPF 15 blocks roughly 90% of UVB rays while SPF 30 blogs about
97% of UVB rays. SPF 50, which is recommended for individuals who have
sensitivity to the sun, blocks about 98%. It is recommended that you choose at
least an SPF 30 with a broad spectrum if you are going to be outside for long
periods of time. SPF 15 is perfect for day to day activities.
Now that we have the perfect sunscreen that fits your needs,
let’s make sure you are applying it correctly. Less is not always more, especially
when it comes to sunscreen. It is recommended to use one ounce of sunscreen for
the entire body. Not using enough sunscreen lowers the amount of SPF coverage.
Studies show that on average, only 20%-50% of the recommended amount is applied.
It is important to not only apply enough sunscreen but allow time for the skin
to absorb the sunscreen before heading outdoors.
Other important information you need to know about
sunscreen:
·
All sunscreens and sunblock’s lose effectiveness
if submerged in water. It is recommended to reapply after getting out of the
water, toweling off or sweating.
·
Unfortunately, wearing sunscreen is not enough.
It is important to wear a hat, sunglasses and lip balm with SPF also!
·
Did you know that the FDA has recently outlawed
the use of words such as “waterproof” or “sweat proof?” FDA ruled that no
product can make such claims. Instead, you will see such things as “water
resistant.”
·
Wearing sunscreen on a daily basis can prevent
the appearance of wrinkles and other signs of aging?
Hopefully this has cleared up the confusion of sunscreen!
Here’s to a happy and healthy summer!
