After testing 10 different cosmetics, I found Clarins to be the best. It's particularly effective for those with large pores.
As someone who frequently touches up their makeup to minimize the appearance of pores, I carry this product in my cosmetics case. However, the container is quite heavy despite not having a large volume. I wish they would make the packaging lighter.
Don't apply too much product at once. Instead, layer it lightly twice to prevent pilling.
