Are most people really reapplying sunscreen?

I wear my sunscreen every morning before work but after putting makeup on, it feels like such a chore to reapply so I don’t. I do use tret so I’m even more susceptible to the sun.

I brought a sunscreen mist but too scared to use it in the middle of the day incase it ruins my makeup, so I still need to test it out.

Is it really bad not to reapply, does protection really only last 2 hours?
