It's hard to manage sebum

My face is overly oily, and I keep getting pimples around my nose. My makeup flakes, and no matter how much I cleanse, the oiliness just keeps coming back.

It was hard to manage sebum. I tried using packs and peeling, but it only improved temporarily and quickly returned to its original state.

My nose and forehead area in particular are getting oily and my pores seem to be getting larger. I've tried various products to control sebum production and am careful about cleansing, but I'm not seeing much effect.

How long does it take to get sebum management at a dermatologist to see results? I'd like to try sebum management.
