ELI5 why Vaseline doesn't give me face acne but simply resting my head on my pillow does?

 I wash my pillow once it gets greasy and dirty.

Vaseline doesn’t clog pores. So it won’t cause pimples. 

You need to wash your pillowcase more often than just when it gets greasy and dirty. And you need to wash your face every with a real face wash. You also sound like a teenager, which means your face is naturally producing a helluva lot more oil so you need to practice even better hygiene.
