What Does SPF Mean & How Does It Work - Different SPF levels (15, 30, 50, etc.) protect your skin from harmful UV rays


What Does SPF Mean & How Does It Work

Before we move to learn why is SPF important, it is essential to know what SPF stands for? SPF, or Sun Protection Factor, is a measure of how well a sunscreen can protect the skin from the harsh UV rays, which are mainly responsible for sunburn.

Consider SPF as a time measure. If your skin begins to burn in 10 minutes without protection from the sun, using an SPF 30 sunscreen theoretically wards off burning 30 times as long (300 minutes). But that is only an estimate, and other factors such as individual skin type and sun intensity can also have an impact.

Sunscreens create a barrier on your skin that is able to absorb or reflect UV radiation. Sunscreens with higher SPF filter a larger percentage of UVB rays. Also remember, no sunscreen blocks 100% of UV rays. Now, that you have learnt what is SPF? Read on to learn why is SPF important.

SPF Tips:

Keep re-applying the sunscreen every few hours.

The numbers alongside SPF indicate the level of protection it provides. For instance, SPF 15 filters out approximately 93% of UVB rays, SPF 30 about 97%, and SPF 50+ an impressive 98%. While it is true that no sunscreen can offer 100% protection, choosing a higher SPF can provide better coverage. If you are someone who spends a long time under the sun, then you need the best coverage.

Consider Your Lifestyle

While learning why SPF is important, it’s equally crucial to understand the purpose of use – is it for everyday protection or for extended outdoor activities?
