Wash your face with warm water first, wash out the dirty things in your pores, and then wash with cold water to shrink your pores. Take a pat with a toner that can astringe pores, and it will get better gradually. Use facial cleanser as little as possible, which makes pores bigger and bigger. If you insist on using facial cleanser, you must use water that shrinks pores, otherwise it is best to use facial cleanser less.
