"Sometimes [back acne] may not be bacterial," Bhanusali said. "Fungal or yeast acne are getting more and more common. An overgrowth of a yeast can lead to a breakout, and for this I use zinc pyrithione products." Zinc pyrithione is often found in dandruff shampoos like the ones ahead, which Bhanusali says can be used as a body wash.
