Your face is covered with innumerable tiny holes called pores, which secrete the natural oils that keep your skin looking supple and healthy. However, when the pores begin producing excess oils, or sebum, they can become clogged, leading to acne breakouts. Some pores on the nose, cheeks and forehead become noticeably enlarged, and when they become clogged with excess sebum, the results are large whiteheads, blackheads or pimples. Help put an end to embarrassing acne breakouts by shrinking your pores and controlling your oily skin at home.

Wash your face twice daily, once in the morning and again before bed, with a mild, soap-free cleanser. Avoid vigorously scrubbing your face, recommends KidsHealth, as this could irritate your skin and make your acne even worse.

Work a cotton ball soaked with astringent or toner over any areas of your face where excess oil or large pores occur such as your chin, nose and forehead. The astringent helps to reduce the amount of oil on your face while shrinking your pores.

Apply a moisturizing lotion to your clean skin. Choose an oil-free product that is labeled "noncomedogenic" or "nonacnegenic," recommends KidsHealth.

Apply a clay mask to your face at least once weekly. Clay masks gently eliminate the excess oil from your skin while reducing the size of your pores, notes dermatologist Noelle Sherber, a contributor to "Teen Vogue." Allow the clay mask to remain on your skin according to the package directions, or for 10 to 15 minutes, then rinse it away with lukewarm water.

Press a cosmetic blotting paper on any areas of your face where you notice large pores or shine associated with excess oil. Blotting papers -- available in pharmacies and beauty supply stores -- work by soaking up excess oils.

Speak to a dermatologist about prescriptions and treatments available for treatment of excessively oil skin or to reduce the appearance of large pores. Crutchfield Dermatology notes that several prescription topical creams are available -- including products containing tazarotene and Accutane -- that will shrink pores and reduce the amount of excess sebum on your face.
