Makeup can be a friend to large pores. To get your face ready for cosmetics, begin with a noncomedogenic (read: won't clog your pores) moisturizer. Then, spread on some primer, which evens out your skin's appearance and puts a barrier between oil and your makeup [source: DocShop].
For foundation, you'll also want to look for something oil-free and noncomedogenic. Some people recommend mineral makeup for people with large pores. It tends to be free of perfumes and preservatives, so it's worth a shot [source: Bouchez].
Remember that your hair comes into contact with your face as well, so try to keep it free of lots of product that can get into your pores.
