Now for oily skin it'll be a bit of a challenge. Oily skin makes you naturally more suseptable to acne, and sadly if you have oily skin, there is no fixing it, but there is ways to maintain it. With oily skin, it's crucial that you cleanse your skin more often and pay more attention to it. The routine I reccommend for people with oily skin goes as follows :
-double cleanse (whether you wear make up or do sports, double cleanse anyways. Use a cleansing wipe or a make up wipe, then apply micellar water)
-toner
-moisturize (oily skin still needs moisture)
-run an ice cube along your face (sounds odd, but it tightens your pores and reduces the oily look)
-sheet mask 1 time a week
-exfoliate 1 time a week
NOTE: people with oily skin especially need to quit touching their face with hair or fingers! These things are naturally oily, and touching your face with more oily things doesn't help! Also, use a sheet mask on Tuesdays.
