What Is SPF Sunscreen? - Sun Protection Factor Explained

Why do we need sunscreen? When you are under the sun and are unaware of where to escape? So, let’s not invite sunburn to our basket of regrets when we can safely avoid this irreversible damage. What can we do to prevent it? Choose a sunscreen with sufficient SPF.

What Do You Mean By SPF?

SPF stands for Sun Protection Factor. What does it determine? The SPF of a sun protection cream or ointment determines the level of UVB protection it contains. SPF products are available in various variants, like SPF 15, SPF 30, SPF 50, and more. Here’s how they work:

· SPF 15 sunscreen blocks around 93% of UVB radiation

· SPF 30 sunscreen blocks around 97% of UVB radiation

· SPF 50 sunscreen blocks around 98% of UVB radiation

If you go through the detailed description of a sunscreen with SPF 50, it will take you 50 times longer to experience sunburn as compared to without sunscreen. A higher range SPF deals with more damaging UVB rays from penetrating than a lower range SPF. So, a higher SPF translates to higher sun protection and lesser skin damage.

What Level Of SPF Is Made For You?

If you spend most of your time indoors or under the shed, you can safely use sunscreen that provides an SPF of 20 or less. If you are constantly traveling and are exposed to the sun, we recommend you liberally apply a sunscreen of SPF 30 or higher. But, it will all get nil if you forget to reapply your sunscreen every two hours. You thought you had to apply sunscreen just once? The answer is ‘No.’

Apart from SPF, the other factors that works like protecting our skin include:

· Your skin type

· Number of sunscreen applications

· Weather conditions and environment

· Time spent in sand and water
