oily face problems

Mary • My beliefs and opinions are constantly evolving
I have a face routine to prevent acne and I no longer get as much as I used to anymore, but when ever I do get pimples it's bc of my oily face and there's just ONE big one 😷
I use oil blotting sheets to help, but it's more of a short-term thing and my face just gets all oily again the next hour! 
So does anyone know any way to treat it where the effects would be more long-term? Thank youuu!
