The natural charcoal is supposed to draw out excess oil so these are perfect for those with very oily skin especially around their T-zone or nose area. It is also said to unclog pores and remove excess dirt, oil and blackheads. The strip itself is easy to use and the instructions on the back are easy to follow. I was a bit disappointed because the strip left black marks on the tip of my nose after I pulled it off gently as instructed. I also noticed that the strip did remove dirt from my pores but the amount it removed was less than the white ultra cleansing pore strips. So if I had to choose I would say that the white pore strips are my favourite because I found them more effective. My skin type is combination so I didn’t really see the difference from using the charcoal but if your struggle is more with excess oil than removing impurities then I’d say the charcoal strip is maybe something to consider.
