I'm wondering if I should continue using acne care products.

My acne hasn't noticeably gotten worse lately, but for some reason, it keeps bothering me.
I tend to get recurring small pimples rather than big ones.
So I'm wondering if I should continue using my current acne care products.
I think switching my acne products might help, but I'm hesitant because I'm afraid it might actually cause more breakouts.
It is even harder to judge because the acne product I am currently using is not very irritating.
I'm also not sure how long I need to use acne products to see results.
I'm also wondering if it's right to switch after using it for a few weeks, or if I should use it for a longer period.
I've heard that acne is an internal skin issue, so I'm confused whether products applied to the surface alone are sufficient.
I'm wondering if I should choose again, focusing on ingredients that help with acne management.
I'm worried that switching an acne product I've been using just fine might make my skin even more sensitive.
So these days, I’ve become very careful with every single acne care product.
I feel like I wish someone would tell me the standards to see if I'm heading in the right direction.
