Generally a milk, lotion, or cream cleanser will be the most hydrating. If you prefer foaming face wash, avoid any with sodium lauryl sulfate or sodium laureth sulfate as primary ingredients because those are both extremely drying. I love Biotherm's cleansing milk for dry skin, but they also have one for combo skin. Even though I have dry skin, I currently use the Prescriptives gel cleanser for oilier skin and it doesn't leave my face feeling at all stripped or dry.
