wash your fucking pillowcases bedsheets/change them more often
stop eating greasy/oily foods so much and shit like chocolate.
drink more water
use a gentle foaming facial cleanser (cerave or cetaphil are the basic 'i dont know what the fuck im doing but im at the store and i need to pick something' brands for all of what im telling you to do)
use a gentle anti-acne product with salicylic acid (take note of how your face reacts to this, use it sparingly or discontinue use if its too harsh or your skin reacts poorly
moisturize (if you live in a dry ass climate, dont apply moisturizers with Hyaluronic acid, otherwise go for it. if you dont mind the greasy feel and your skin is in dire straits, you can use vaseline, which also works great for elbows)
if nothing improves or you have deep, cystic acne, see a dermatologist, they might have to prescribe you something gnarly and harsh
