How should I care for small, pimple-like acne?

Lately, perhaps due to the change of seasons in autumn, I've been getting breakouts that I don't usually get.

It's hard to say if this is skin trouble caused by oil, and honestly, I still don't know the cause.

I've been getting small breakouts—I'm not sure if they're millet or what—that I can't squeeze.

So whenever this happens, I don't know how to manage it.

Regular acne can be managed by extracting it as time passes, but

I can't squeeze these tiny pimples, and it seems like they just need to go down.

There hasn't been any real change, and it seems to be staying at a similar size without calming down, so I don't know what to do about this.

I'm always debating whether I should take care of it or not. Skin trouble is so difficult.
