[Routine Help] pimples consistently in one spot

pretty much every single pimple that i’ve gotten in my life has been those painful cystic pimples all in one spot, on the side of my face right by my sideburns. i’m a side sleeper so i’ve narrowed it down to that being the issue, but i can’t solve it. i’ve started changing my pillowcases every night, spraying them with hypochlorous acid, and having a consistent routine but nothing’s working. the only thing that seems to work is sleeping on my back. was wondering if there were any other options i could try, or should i just start forcing myself to sleep on my back full time lol.
