I adopted the Korean skincare method about a month ago, specifically the 7-skin method, and it has done wonders for my skin! I used to be oily and acne-prone but I honestly believe this toner has helped balance my skin. I'm no longer oily (except for my nose due to large pores), I rarely ever get breakouts now, and my skin has never felt so soft! I often find myself just touching my cheeks to feel how soft they are. I've even tried to get my friends and family to feel my cheeks! LOL I loved this product so much that I've already purchased the 200ml as a backup once I've run out of my current bottle. I use 1-2 dashes/drops(?) of this every morning and night for at least 3-4 skins, alternating with other essences/toners depending on what my skin needs. So I still have over half the bottle left. Love love love!
