This blog breaks down SPF in simple words, clears up common sunscreen myths, and helps you choose the right SPF for your skin.
Sunscreen is your skin’s shield against sunburn and long-term damage. But with so many different SPFs, how do you pick the right one? Let’s make it simple!
What is SPF?
SPF stands for Sun Protection Factor. It tells you how long a sunscreen can protect your skin from burning.
For example, SPF 30 lets you stay in the sun **30 times longer** before burning compared to no sunscreen [Source].
SPF 30, 50, and 100 – What’s the Difference?
- SPF 30: Blocks **97% of UVB rays** and is great for everyday use [Source].
- SPF 50: Blocks **98% of UVB rays**—a tiny bit more than SPF 30 but not a huge difference [Source].
- SPF 100: Blocks **99% of UVB rays**, but the extra protection is **barely noticeable** [Source].
Which SPF Should You Use?
- Everyday use: SPF 30 is enough for daily activities like going to work or running errands [Source].
- Outdoor fun: If you’re hiking, swimming, or playing sports, go for SPF 50+ [Source].
- Extreme sun exposure: If you’re skiing or at the beach all day, SPF 50+ with **frequent reapplication** is best [Source].
