Strong suction
This think sucks...literally. It really will pull your skin 1/4"  into it if you don't keep it moving. Even then with the power it has, I found the results to be no better than manually getting rid of blackheads. This thing actually hurts more. I also ended up somehow having my skin start to peel a couple days after using this. I guess YMMV. Good luck reading the "manual" that comes with it - the English is terrible. Could hire a US high school kid for a few hundred and get a far better and actually readable manual.<br />I think there are probably far better ways to get this done than essentially a mini vacuum.
