In this article, we will discuss everything that you need to know about SPF in sunscreens. Without further ado, let’s get started!

What is SPF?

If you want to know “what is SPF,” we should start with its full form Sun Protection Factor. The SPF of a sunscreen reveals the level of UVB protection provided by it. You will come across skincare products with various sun protection levels, including SPF 15, 30, and 50.

Let’s explain how different SPF levels work.

  • SPF 15 can block up to 93% UVB radiation.
  • SPF 30 can keep out around 97% of UVB radiation.
  • SPF 50 can prevent around 98% of UVB radiation from getting absorbed by your skin.

In simple terms, an SPF 50 sunscreen ensures that your skin will experience sunburn 50 times lesser compared to without sunscreen. ensures it would take you 50 times longer to experience sunburn as compared to without sunscreen. A higher SPF range will obstruct more damaging rays from penetrating through the layers of your skin than a lower range SPF.

In an ideal world, higher SPF will offer increased sun protection and reduced skin damage. But using sunscreens with SPF 75 or 100 doesn’t make much sense. Keep scrolling to understand why.

Sunscreen SPF and Skin Protection

If you mostly stay indoors and spend minimum time outside, you can work with an SPF 20 sunscreen or even lower. If you remain exposed to the sun for long hours or travel continuously, you should go for sunscreen with SPF 30 or more. Other than SPF, factors that affect the level of protection your sunscreen offers are as follows:

  • Skin type
  • How frequently you apply your sunscreen
  • Weather and environmental conditions
  • Whether you sweat too much
  • How much time you spend around reflective surfaces like sand and water

Why Not Use a Sunscreen with a High SPF?

Several people are of the misconception that sunscreens with high SPFs are more effective for their skin. But the truth is SPF 100, or SPF 75, does not offer considerably better protection than an SPF 30 sunscreen.

For wide spectrum protection, the UVA protection needs to be at least one-third of the UVB protection. Sunscreens with a high SPF usually offer higher UVB protection than UVA. Therefore, it creates a false sense of increased protection for your skin.
