Coconut oil is supposed to be really comedogenic I thought... meaning it's heavy and tends to clog pores. You want to look for non-comedogenic products if you want to use them on the face. Jojoba oil is supposed to be really close to the oil our skin produces natural. I've also heard hazelnut oil is, but I haven't looked into that one much.

The thought process behind using oil to clean is that oil dissolves oil, where as oil and water just repel. So a search on here for the "Oil Cleansing Method" or "OCM". There's a huuuuuuuuuuuuuuuuuge thread about it with lots of links to read up on the process. I did it for awhile, and it certainly didn't make my acne WORSE. I didn't see a noticeable improvement either though (mine is hormonal though so maybe that's why?)
