Blackhead and whiteheads occur when the pores on your skin become clogged with excess oils. Blackheads, also known as open comedones, are open spots on the surface of your skin where blocked oils turn black inside of the pore. Whiteheads, also known as closed comedones, are not open at the surface, so the clogged oils appear white. Clogged pores can become enlarged, and the removal of whitehead or blackhead leaves a large, open pore. Proper treatment of your skin can help reduce the size and appearance of your pores; however, they will never close and may never return to their original size.

Treat your skin to a microdermabrasion treatment, either at home or at your dermatologist's office. The abrasiveness of the treatment removes the top layer of skin, revealing new skin beneath the surface layers. It also encourages collagen production, reducing the size and appearance of your pores.
