Why does SPF matter?

Let us first know, when exactly did SPF come into the discussion? Studies have shown that intense sunlight can affect the skin and cause cancer. We need to protect our skin from such harmful sun rays, the researchers said. That's why SPF has become an important part of skincare!

What is SPF?

SPF stands for Sun Protection Factor, which measures how long your sunscreen will protect you from ultraviolet rays (UV rays).

There are two types of UV rays - UVA rays and UVB rays. UVA rays cause aging, wrinkles, and sagging, while UVB rays cause skin burning, which leads to excessive tanning. The combination of UVA and UVB rays can be more dangerous for the skin.

UV rays can damage your skin -

UV rays affect the outer part of the skin. As a result, it affects your skin and increases the chances of developing skin disorders. UV rays are strongest between 10 a.m. to 4 p.m. when the sun is highest in the sky. Therefore, it is important to apply sunscreen so that your skin is not harmed if you are exposed to the sun's rays during times when the sun's rays are intense.

 

Does the Number Matter?

The SPF number essentially tells you how long the sunscreen will protect you from UV rays. For example, using an SPF 15 sunscreen means you will take 15 times longer to burn compared to not using sunscreen at all.

According to the Environmental Working Group (EWG) and Skin Cancer Foundation, SPF 30 blocks nearly 97% of harmful UVB rays, SPF 50 blocks about 98%, and SPF 100 blocks about 99%. Well, although the differences in SPF values are large, there’s very little difference between how much UVB they filter. According to researchers, SPF 30 gives you relatively more protection.
