In climates with high humidity pores can become larger and more visible. Having open pores allows bacteria to enter and cause a break out. There are some tricks to help your pores stay clean and encourage shrinking, but there are no miracle products to diminish their appearance entirely.
Washing your face with cold water helps to reduce the size of pores as cold water closes them whilst hot water opens them. The next step would be to apply a toner. You can use anything from tea tree oil to witch hazel. If you're feeling your pores need a lot of help it can be useful to keep washcloths in the fridge and leave them on your face for 5-10 minutes. A more dramatic approach would be to use icepacks on your areas of concern. A combination of both, is very effective. Try using a cold compress during the week and ice on the weekends.
