Have just bought some jojoba oil to use with my incredibly oily skin. I'm not sure whether its best to use instead of moisturiser or in some other way? I used a couple of drops this morning as a moisturiser replacement and my face is still an oil slick. Is it something that takes a while to help? I had to give up on rosehip oil as it broke me out but I'm running out of options to try with my greasy face. The only thing that has helped is roaccutane while I am actually taking it. Have had 3 courses but my face is as oily as ever within a month of stopping. Please give me hope that jojoba may be the answer!
