Well the oil in mu is something you can't control. You don't get to choose the oil. It's often mineral oil, which causes a bad reaction for some, or just oil your skin doesn't prefer. Also, for some it's the combination of the ingredients used in mu and not simply the oil alone.
I have dry skin so I don't generally have to wait for oil to soak in. If you have oily skin you might only want to use it at night. You just have to find what works for you. Jojoba is a really light oil and it's supposed to mimic your skins natural oils.
