I highly recommend Missha cleansing oil.

The cleansing oil product I use is the Missha Super Off Cleansing Oil Blackhead Off.

It is said that with the 2X Melting System, it not only deep cleanses everything from waterproof to long-lasting makeup without leaving a trace, but also provides pore care effects by containing apricot kernel oil, tea tree leaf oil, drumstick seed oil, and Houttuynia cordata extract to care for sebum and blackheads.

It is a popular product because there are many reviews stating that it effectively cleanses not only heavy makeup but also skin impurities in a single step, and that it is actually good for removing and managing sebum and impurities.

So I have also been using it for several years, and I like it because my skin feels very clean after washing my face.
