Another great product from Cosrx that I have had a chance to try. This one is, in my opinion, suitable for oily skinned people. It provides sebum control, as it contains BHA and other useful ingredients. It comes in a 100ml bottle so it should last you a few months. It is inexpensive (or to me at least). I have only used it for a few days but I do notice my oily t-zone does get less oily. But I also use more products for oil control too. Well give it a try!
