I have the same problem with large pores. Unfortunately, you cannot shrink your pores (thanks to genetics ), but steaming the skin and keeping them clean makes them appear smaller. I (although I have good skin) use Proactiv (it is EXCELLENT) daily. During my showers (the steam opens the pores), I use the facial cleanser then follow with WITCH HAZEL on a separate, clean, dry cotton cloth. I hope this helps.
