What Is SPF Number? 

What is SPF Number

SPF is nothing but a measure of how much sun exposure/UV radiation is required to cause sunburn on your skin when it is protected by sunscreen relative to the amount of sun exposure needed to cause sunburn on unprotected skin. To put it simply, the sun protection a sunscreen provides increases when the SPF value increases. Using sunscreen is the best way to protect your skin from all sorts of damage that can be caused by the harmful rays of the sun due to prolonged exposure, daily. 

How SPF Is Measured

The SPF number is determined by the amount of sunlight required to produce redness in skin which is protected by sunscreen, divided by the amount of sunlight that produces redness in skin which doesn’t have sunscreen on. 

Different Types Of SPF

Now that you know what does the number on your sunscreen mean, it’s time to select a sunburn sunscreen that fits your needs and protects your skin effectively.
