Steam can help unclog pores and therefore reduce oil in the nose. Wash your face first and then remove any makeup. Heat a covered pot of water on the stove on medium heat until it starts producing steam. With a towel wrapped around your head, open the pot and lean over it. Let your skin absorb some of the steam. Spend 10 minutes soaking up the steam. Some people prefer to add dashes of things like peppermint or chamomile tea, as this may add some extra pore cleansing power. Some people find lemon helps remove dirt from the nose. To use a lemon, mix three drops of lemon juice with enough sugar to form a paste. Apply this solution to a cotton pad and then rub it on your nose. Do this three times a day to see if you notice a reduction in oil. Grind a single almond into small fragments using a rolling pin or food processor. Mix in a small amount of honey and then apply the almond to your nose. Let it rest for 15 minutes before washing it away. Mix a solution of equal parts water and vinegar. Then, dab a cotton swab in the solution. Press the cotton swab to your nose for five minutes. Then, let the solution sit on for 15 minutes before washing it off.

TL;DR in Vietnamese:
Xông mặt để làm sạch da. Thoa nước chanh. Dùng hạt hạnh nhân nghiền nhỏ. Thử dùng giấm.
