Another COSRX product that have visible results. I decided to use it for my forehead where I have a little bit oily skin and some clogged pores, and it really cool for this purpose, not sure that it should be applyed to a dry skin, but I haven't got any iritation while using it on cheecks for example. It is nice that the main ingridient is Salix Alba (Willow) Bark Water (88%) which is the natural souce of a salicilyc acid. So, I have less irritation, pimples(almost none) and less oily skin. Also. it givws an effect of a "glass skin" at some point. Thanks, cosrx!
