Organic vs. Inorganic Sunscreen?

Hello. I have oily skin, and I usually just look for and use sunscreens that don't feel too heavy or suffocating.

So, I bought a Biore product once while traveling in Japan, and since it was thin and moisturizing like an essence, I repurchased it in Korea and am currently using it.

By the way, what is the difference between organic and inorganic sunscreen ingredients?

I didn't really know much about it, so I didn't pay much attention when buying sunscreen, but I suddenly became curious about which ingredients and sunscreens would suit me better.
