I've only been using this product for a few days, and as of yet have not noticed any results on the size of my pores. However, I tend to get very shiny on my nose very quickly and constantly throughout the day. This product has really helped with that. It definitely give me a matte surface to start the day with, I still get a little oily a few hours in, but a blot sheet and I'm good to go. I also sweep this over my eye lids and my shadows last forever without a primer. Because of its herbal smell, I wouldn't recommend that if you have very sensitive eyes, but it works great for me. I definitely enjoy this product, I'm just weary of its pore shrinking abilities.
