Pore Strips Review Pore strips are a classification of blackheads treatments. They are not targeted at all toward acne, but specifically blackheads. They come from companies such as Biore and Clean and Clear. But they can be extremely expensive for some. The best effects can come from heating the nose with a hot washcloth before application. But application takes some time, especially considering it has to dry. Products like Biore use ingredients such as titanium dioxide and butylene glycol, which can damage the skin easily, but they do not actually use acne fighting or pore decreasing ingredients. The biggest problem with these items is that first, you do have to heat the nose before to loosen the bacteria, or it can be extremely ineffective at best. And second, pore strips often leave gaping and open holes, inviting bacteria to again gather quickly into the pores and cause more blackheads. They may seem cheap if you don’t consider how many you will have to use every month. But pore strips are not worth it at this time.
