hmmm...i should try jojoba oil. i have never tried the olive oil/castor oil mixture, but i do use dhm's cleansing oil - have used it for over a year now and love it! my skin looks so much better since i've used an oil cleanser! i have been thinking about just getting my own olive oil from the store and trying it, but have been afraid it would break me out or be too heavy or something. maybe i should save my dollars and cents! while dhc cleansing oil is great, and lasts a long time, it does add up. if you can use the stuff out of your cubbard, why not? if you can use it and you have oily skin, i should be able to use it on my drier skin. thanks for the tip!
