They Target Blackheads
On the previous page we discussed substances building up in pores. It's that process that leads to blackheads. Technically a type of acne, a blackhead occurs when the material in a pore is pushed out through a follicle. It's when the buildup reaches the skin's surface and reacts with oxygen that it turns black.
Blackheads are what pore strips are designed to remove. If you look closely at a strip after it has been pulled from your face, you can see dozens of tiny, dark, hair-like stalks on the underside of it. What're you're looking at are the contents of your pores. And once these blackheads have been removed, you'll notice clearer-looking skin.
Of course, such results aren't permanent. You'll find out why on the next page.
