How can I find out the different types of sunscreen?

There are various types of sunscreens used for UV protection, such as mineral, chemical, and hybrid types.

How can I tell what kind of sunscreen I am using?

It isn't written on the sunscreen case, so I can't tell.

Is visiting the product website the only way to find out?

I would like to distinguish between mineral, organic, and hybrid sunscreens.
