What Is SPF?

What Is SPF?

 

SPF stands for Sun Protection Factor, or “the level of sunburn protection provided by the sunscreen product.”  

The SPF test measures the amount of ultraviolet, or UV, exposure it takes to cause a sunburn while a person is wearing a certain sunscreen, compared to the amount of UV radiation it takes to burn while a person is wearing no sunscreen at all.   

The higher the number, the greater level of sunburn protection.  

 

 

Does a Higher SPF Really Mean More Protection?  

It’s a common misconception that higher SPF means you’re preventing more damage. In actuality, there is very little difference between SPF 50, and SPF 100.

 

SPF 15 Blocks approximately 93% of UVB rays
SPF 30
Blocks approximately 97% of UVB rays
SPF 50
Blocks approximately 98% of UVB rays
SPF 100
Blocks approximately 99% of UVB rays

 

 

Even though the difference between SPF 50 and SPF 100 is over 50 points, the percentage of UV protection only increases 1%. 

If you’re applying your sunscreen correctly, any SPF between 30 and 50 will provide sufficient protection, even for those with the most sensitive skin.


 

What is Broad-Spectrum SPF?

 

Harmful sun exposure reaches the surface of the earth in two forms 

  • UVA rays cause aging, like wrinkles and age spots.  
  • UVB rays cause sunburn.  

 

UVA rays are the sun's rays that are responsible for tanning the skin. These rays can cause damage to your skin's cells below the surface, and may cause skin cancer, premature aging, and wrinkles. UVB rays cause sunburn, damaging the skin’s top layer. Broad-spectrum sunscreens block both UVA and UVB radiation.

Protect yourself from a range of sun damage by selecting not only the correct SPF but also a sunscreen with “broad-spectrum” protection.

How Can I Be Sure I’m Safely Protected?

It’s always important to remember that no sunscreen can block 100% of the sun’s rays. To be sure you’re getting the coverage you need, opt for a “physical,” or mineral sunscreen. Mineral sunscreen acts as a shield against the sun’s rays.

With the power of minerals like Zinc Oxide and Titanium Dioxide, physical sunscreens are not absorbed, but sit on top of the skin. When it comes into contact with sunlight, these sunscreens bounce UV rays off of the skin’s surface, thereby preventing radiation from ever entering the body.
