How to read the UV protection factor

You know how sunscreens have SPF and PA written on them?

There are also some with a plus sign at the end.

I didn't know what this was, I just looked at the brand

I think I bought it, so I looked it up.

 

 

First, the SPF and PA notations are

It is said to indicate the degree of UV protection.

For example, a sunscreen with SPF 30 contains the amount of ultraviolet rays

They say it means it becomes 1/30. For example, when speaking of a person who develops erythema within 15 minutes of exposure to ultraviolet rays.

You can expect redness to occur within 450 minutes of applying this cream.

 

The '+' sign indicates a value above a certain level.

In Korea, if the SPF is 50 or higher

Values ​​above that are considered to have no functional difference.

They say it is marked as 50+.

 

 

 

In other countries, there are products with SPF 100, but the Korean Food and Drug Administration limits it to only 50+.

 

In my case, it's the "it has to be this" type.

I don't have sunscreen, so I buy things for the kids at the supermarket or

Or if you have a product you received as a gift

I tended to study the numbers after looking at that product.

I received this product as a gift; it has SPF 50+

It's a sun stick. Use it when you do a lot of outdoor activities.

I think it would be good.

 

I'm sharing this in case it helps when you're buying sunscreen or sun sticks~
