Cleansing oils are fairly popular in the beauty scene, particularly in Asia. They're mostly used to remove makeup, but wash off cleanly with water. Read: cleanly. There's (generally) no greasy feeling, no oily film... just clean skin! The double cleansing method is my favourite way to remove makeup because I find that it generally removes most (if not all!) of my makeup in the first cleanse, and it involves a cleansing oil. I never really thought about how cleansing oils work until Erik (my fiancé) asked me how the oil helps to remove makeup. This made me think about it and want to do some research!
