Honestly, I think it could be for either. If I had oily skin I would only use it at night. One thing I really do like about this though is it doesn't feel really greasy. It goes on and soaks in pretty easy.
Definitely more suited for dry skin, but I have combo skin and use this in the winter and it's amazing for me! I would use this as a night cream because it's thicker and a thinner moisturizer in the morning.
