What should I do if there is grease in the pores of my nose?

You should choose a cleanser with stronger cleaning power, which is suitable for your skin. I am a mixed skin cleanser. I use pond's seaweed salt to wash my face, which is quite useful. You can also use Clarins suction cup facial cleanser. Just use cleansing oil and ZA's Deep cleansing oil twice a week. Make a hydrating mask, and the pores will be smaller.
