Basic skincare routine suitable for acne-prone skin

I thought acne would just be a one-time thing during puberty and then be over, but it just won't go away even after becoming an adult.

Since I have very oily skin, I always double cleanse and pay close attention to my cleansing routine.

Of course, I also wipe my face thoroughly with a toner after washing it.

My question is how you do your basic skincare.

According to various sources, it is recommended to apply multiple products in layers after washing your face.

I was wondering if this might be worse for acne-prone skin.

I think it would be better to just keep it very simple and just moisturize.

I am confused because there are many conflicting opinions (such as the need to apply multiple layers to strengthen the skin barrier, etc.).
