Cleansing oil

I always used only water because I thought using oil would make it greasy, but then I heard that oil should actually be washed with oil.

I happened to buy cleansing oil at a low price thanks to an event, and I'm already almost using up a bottle.

Whenever I feel dead skin cells building up on my face every few days, I apply oil and roll it around, and I can feel the blackheads being pulled out.
