If you have oily skin or have a naturally darker complexion you may have larger pores naturally. Ask any expert on large pore problems on this website that most important aspect is knowing what products work and which don’t. Other than that regular cleansing and exfoliation are key in combating blemish formation.
The most important factor that helps keep your pores looking small is proper cleansing. During the day make sure to use non-comedogenic moisturizers and makeup; avoid products that contain heavy ingredients, like petrolatum and mineral oil, both of which may irritate pores and make them look bigger. Always wash your face with a gentle cleanser before bed to make sure that the day’s dirt and make-up don’t end up clogging your pores. Cleanse before and after working out, since sweat can carry cosmetics and debris to pore openings, where they’ll settle in and stretch the skin. When you cleanse, consider doing it with a power brush, such as the Clarisonic MIA Skin Cleansing System ($99, sephora.com).
Now the other factor is exfoliation, which is meant to remove dead cells from the skin’s surface. These dead cells play an important part in clogging up your pores and enlarging them. If you have hard skin that doesn’t get red you should exfoliate daily, if you have sensitive skin one to three times a week should be good. Choose an over-the-counter gel, mask, or lotion that contains a proven sloughing ingredient, such as alpha hydroxy acids, retinol, or fruit enzymes.
