A parasol wouldn't block UV rays, right...?

Whenever I go outside, I always make sure to apply sunscreen.

I am using it even though I have to use a parasol.

Sometimes, when I just really go to the neighborhood for a quick visit or something like that

I want to go out and come back just wearing a parasol.

That's how it is... these days, as soon as the sun is up

It felt hot even in the morning.

Even if I go out for a light walk

It wouldn't be good to go out carrying only a UV-blocking parasol, right? Since so many good UV-blocking products are coming out these days, I'm getting curious for no reason.
