Excellent question. OK, I am a little strange, as I don't use a cleanser, just Ivory soap and water. I have tried different cleansers and other soaps in the past, only to find that they irritated my sensitive skin and frequently caused breakouts, (I have rosacea as well as acne - the acne is pretty much in remission now, thanks to spironolactone, knock wood. I wish I could say the same for the rosacea).

Anyhow, my derm was surprised that I use Ivory soap, as she said it is drying for adult skin. Funny, but it doesn't dry my skin out at all and actually seems to help with the oiliness. My Dad also uses Ivory and he is 75 and has very oily skin, (as I have his skin type, something tells me I'm in this for the long haul)...
