I get breakouts if I reapply sunscreen too much. Is this sunscreen not right for me?

The sunscreen I use is Scinic sunscreen.

I usually reapply sunscreen about twice a day.

Then. I am using the sunscreen I am currently using without any problems either.

But when I go on trips, I spend a lot of time outside, so

Usually, I reapply it every two hours.

Then I always end up with skin problems.

If you have a very small pimple,

Or... I get breakouts that form like lumps and can't be squeezed.

I wonder if all sunscreens are like that...

Or maybe the sunscreen I'm using just doesn't suit me... I'm curious.

But... then again... I'm usually fine... It's a bit puzzling...

Why am I having this kind of trouble?
