How do I stop blackheads 🥵

My nose is a problem area for me definitely.. I try really hard to get rid ofblackheads but they still appear.. they’re only getting bigger and bigger 🥺 how do I prevent it? I don’t touch my nose or anything and I wash my face 1-2 times a day! I exfoliate weekly and use a oil free moisturizer.
