I had sebum that would just sit deep in the skin. Forming bumps and closed comedomes all over (face,, neck, back, chest). Pinching it was hard because it was so stubborn and deep set. Once it formed it would just stay there, for weeks/months. If it progressed into a red, ripe pimple then it would eventually pop, and that'll be the end of it. But these closed comedome just STAYS there.
This vodka method really helps. After 2-3 days - apply once to twice a day, the sebum, closed comedomes, are surfacing!!! I can finally pinch in with a warm cloth and out they come!
