How do I distinguish between mineral sunscreen and chemical sunscreen?

I knew that I needed to use sun care because UV rays cause aging effects such as freckles, age spots, blemishes, and wrinkles.

I overlooked the fact that UV rays continue to be present even on cloudy days because clouds or glass cannot completely block them.

 

Also, regardless of my skin type, I simply dislike stickiness and find it inconvenient to apply liquid sunscreen on the street. Since it is easy to carry and use, I keep the same AHC stick product (AHC Natural Perfection Double Shield Sun Stick) in my office and car and use it.

 

Reapplying every 2 to 3 hours isn't being followed either.

I apply it before going out, rub it in while looking in the mirror in the bathroom, and have been doing my sun care without distinguishing between organic and inorganic sunscreens until now.
My skin isn't very sensitive; it's just slightly oily.

 

Since I work, I have quite a lot of outside activities.
However...

I looked at the product and it isn't marked anywhere.

1) First of all, how can I distinguish whether a sunscreen is organic or inorganic just by looking at the product?
2) Do I need to purchase organic and inorganic sunscreens separately?
3) How do the uses of organic sunscreen and inorganic sunscreen differ?
4) Is this product a mineral sunscreen?
