I use clearasil (sp?) Its not expensive but it works for me. I guess the cream is good for getting rid of zits, the cleasning pads help prevent and treat acne. I see ads for Oxy all the time. I havent heard of Nivia or Noxema and wouldnt be the #1 person to ask, but its cheap and works for me. My friends says to switch every so often so your skin doesnt get used to one brand and wont work for other stuff. Idk.

Good Luck!
