Try beautywithin channel in youtube they explain it very well scientifically. I struggled with hormonal acne most of my teenage hood. Here's a few things to look out for-
Drink water yes cliche but keeps your cells regulating normally
Pillow covers! You shed 40k facial skin cells a day so that clogs up your pores, change them every 3 days if you can buy silk pillow cases they're the best and not very expensive.
Dandruff is a big one so make sure you shampoo every 2 to 3 days.
Double cleansing (oil&foam cleanser) if you can and moisturise even if you have oily or combo skin, when you don't moisturize your sebum glands secretes more oil not only making your face shiny but also clogging pores, moisturizer is a barrier.
There's serums and toners you can incorporate into your regime salicylic acid for example or Ahas and Bhas.
