Despite the longwinded name, it is a simple oil cleanser that's supposedly gentle, perfect for the dry climate my parents live in. It is unscented but doesn't smell funky, and it rinses completely clean but not squeaky, which means my skin isn't tight or dry afterwards. I would say its only fault is its price, just a touch expensive at over $10 for only a tiny bottle of 120mL. It's still better than FANCL Mild Cleansing Oil though, which rings in $26 for the same size bottle!
Anyways, the 120mL lasted me about 6 weeks with daily liberal use of 4 pumps. I went back to using the super heavy Allie Extra UV Gel Mineral Moist N SPF50+ PA+++ due to the dry winter at my folks, so I needed a good dose of cleansing oil to get that thick layer off my skin. In general I think you don't need that much, so if I were to reduce that usage to 2 pumps each, a bottle should last 12 weeks instead.
