I started using MAC cremewash to clean my face about 18 months ago and have had only about three zits since then. My skin is "combination" in that my cheeks are dry but my chin is oily and it tackles all that like a champ. It's not the cheapest in the world ($19 at Macy's last time I bought it) but a 100mL tube can last me almost 6 months.

I keep the nearly empty tubes around for travel but I should find something small to transfer it into for plane trips without grief from the TSA.

MAC also gets bonus points for not making it smell all flowery or strange. Don't get me started on how Aussie changed all their hair products to make them stink like coconut so I don't use them anymore.
