I have extremely enlarged pores across my cheeks and nose, and no amount of foundation will cover them up. First, I scrub my face mercilessly with exfoliating gloves (in this case only manual exfoliation will do). I also use a lotion, toner, or acne pad with 2% salycic acid (hope I spelled that correctly). Almost any acne medication will contain this ingredient, so don't feel compelled to spend a lot of money. Drugstore toners are the cheapest solution and they wont leave a strange residue or compete with your other lotions. They also have the added benefit of drying out the tips of blackheads to help them slough off more easily. In my case, most of my enlarged pores are so large that the blackheads are not even visible any more. If you have any pores that are as bad as mine than you will need to fill them in with a heavy, slightly powdery, stick concealer. Expensive brands are much more smooth and emolient so it might be best to use a very inexpensive drugstore brand, not your usual undereye concealer. Drag the stick across the affected area, pressing firmly in order to literally fill in the pores. Avoid smaller pores that still have some chance of healing, or you will only make them worse. Now it should look like your wearing a thick skin tone facial mask over the area. Wipe all of it off with a smooth damp tissue, leaving only the pores filled in. Don't be tempted to use makeup remover, a rough towel, or lots of water. Now you can apply your foundation as usual. This techique can also be used to fill n deep pit-shaped acne scars.Remember the concealer part of this tutorial is only to be used in worst case scenarios, like mine. If anyone has some criticisms, or their own tips on how to deal with severely enlarged pores, I would love to hear them. Has anyone heard of this technique before? Thanks!
