I have recently purchased these pore strips, because I have a lot of blackheads. I have tried both the tea tree one and the charcoal one, and the only difference is that the charcoal one is black. It did not hurt that much when I took it off, and when I did I did see some gross things on there. I really did not see less blackheads on my nose though. This was only $3.80 so I did not really expect much from it anyway. It does work, but you just cannot see a significant difference after using them. Hope this helped somebody. (:
