What You Need To Know About Sunscreen


SPF, UVB & UVA... What's the difference?

According to research done by the School of Medicine at Northwestern University, 43% of people [that they polled] don't know what SPF means. SPF: is an acronym for Sun Protection Factor. 

People think that SPF includes everything (UVA and UVB rays), but SPF only measures UVB rays. The most misunderstood part of sunscreen is UVA,  “UVA is around every day; it can penetrate through window glass,” Like UVB, it is also related to an increased risk of skin cancer, but unlike UVB, it’s not filtered by the ozone at all. UVA doesn’t cause sunburn, but “it really leads to darkening and aging, because it penetrates deeper into the skin and has more influence in the collagen.

Broad Spectrum & Active Ingredients 

There’s only one way to tell whether your sunscreen offers UVA coverage: the words “broad spectrum.” More active ingredients protect against UVB than UVA rays. Look for active ingredients like zinc oxide, a natural sunscreen ingredient that physically—instead of chemically (like the popular oxybenzone and avobenzone chemicals),—blocks rays. Zinc oxide protects against both UVA and UVB rays.

This being said, 

So below we've listed out a few other things that you can do to make sure you are as protected as possible from harmful UVB and UVA rays.

 

 

Even if it is overcast and cloudy outside, UV Rays can still pass through clouds and penetrate your skin.  Additionally, if you're near reflective surfaces such as water, white sand, concrete, snow or ice-- all of these surfaces reflect the sun's rays and can cause sunburns.

While you are more likely to get burned between the hours of 10am-2pm when the sun's rays are the strongest, any time the sun is shining you have a chance of getting a sunburn. 

Knowing all of these facts can help you limit your sun exposure, and keep you from getting a sunburn, but only if you wear the proper protective clothing and use an adequate amount of sunscreen.
