How to manage acne on oily skin

I have oily skin and acne-prone skin, so even in the middle of winter, my face gets oily in the evening, and when I'm in a warm room, my face gets shiny because of the sebum secretion. So, not only do I have small whiteheads or millet heads, but I also have one or two pustular pimples on my face almost every day. How can I manage my excessive sebum secretion even as an adult? Niacinamide, which is said to be good for controlling sebum, didn't really work for me.

Even in the winter, I can't properly pay attention to my pores or other things because I'm trying to manage my acne. Is there an effective way to manage acne?
