The key to pore cleansing is 5 minutes of 'steam towel' before washing your face.

If you feel like your nose or butterfly zone is clogged with sebum, be sure to try this. I make sure to use a steam towel once or twice a week before washing my face in the evening. I wet a clean towel with water, microwave it for exactly 30 to 40 seconds, check my wrist to make sure the temperature isn't too hot, and then gently place it over my entire face for about 5 minutes. Doing this allows clogged pores to gently open with the warm heat, causing hardened sebum and dead skin cells to swell up. If you then wash your face as usual with cleansing oil or foam, the impurities deep inside your pores wash away really cleanly without having to forcefully squeeze them out with your hands. If you touch your skin right after washing, the texture feels completely different!
