@candyquilt-- You might want to give it a try. If it doesn't clog your pores or make your skin very oily, it should be fine.
I use castor oil directly on my skin when my skin is very dry and irritated. But I use it more like a mask. I allow my skin to absorb it for a little bit and then wipe it off. I don't think I could walk around with oil on my face. It would be very bothersome. But if you mix a little bit with an oil free moisturizer you already have, it might just work. I suppose it depends on how dry your skin is.
I know many people who use castor oil as a face or body moisturizer though. It's a great beauty oil.
