Which is better for dry skin, organic or inorganic sunscreen?

Sunscreen becomes more important as you get older, you know.

I used to just use it as long as it was cost-effective and didn't sting my eyes.

But I’d like to take this opportunity to ask a question.

Do I need to use organic and inorganic sunscreens separately?

Do I need to check that as well when buying sunscreen?

In that case, what kind of sunscreen should someone with dry skin like me use?

What is inorganic sunscreen and what is organic sunscreen?

I guess I wrote it without knowing better.

Since I use a lot of sunscreen, please recommend a cost-effective one.
