I've had horrible peeling skin before due to acne meds. I would recommend only washing your face twice a day with a very very gentle cleanser, such as Purpose, Cetaphil, Basis, or Neutrogena Extra Gentle Cleanser. After washing, spread a little tiny bit of jojoba oil over your skin. Don't be worried that it's oil - it won't cause you to break out. After the oil sinks into your skin, follow up with a good moisturizer such as Aveeno or Eucerin. I wouldn't try to treat the acne until your skin stops peeling. Once it does, I recommend you try a sulfur or salicylic acid based treatment and avoid benzoyl peroxide altogether.
