Going in for a facial to make sure her pores are nice and cleaned out would be helpful and then continuing on a good clean routine. Using a clay mask the morning of will help to temporarily mimize the siz eof her pores. I have found that Immunare foundation works really well with large pores or using a foundation primer prior to foundation application.
