Skin problems

I normally don't get pimples. When I do get something really doesn't want to go away. I try scrubs and mask, but the pimple keeps coming back. Why do I keep getting the same pimple over and over again sometimes? According to the Cosmo magazine it's because the pore keeps getting reinfected. They suggest that I use heat to kill off the bacteria. They are advertising this thing called Zeno hot that gets up to 118 degrees. It's suppose to feel comfortable but I doubt it. You are suppose to leave it in the infected area for two seconds. Pretty groovy if you don't mind burning the shit out of yourself... LOL that was funny! It cost 40 dollars just incase you are interested.
