Hi Karen - I'm no expert, but here's something I picked up from trying different products. I tested slightly oily. About a week after I started using moisturizers (after reading the book), I started noticing that my pores were getting a lot more noticeable. :o I had never seen them look so big! I cut back on the amount of moisturizer I was applying and my big pores returned to normal almost immediately. (I guess too much of a good thing isn't a good idea - I was so excited about my new products that I was loading on the night cream.)
I never realized how too much oiliness/moisturizer could lead to the big pore effect. So maybe cutting back on oily products (either use sparingly or eliminate) would help. HTH!
