Who doesn't know about this? Holy grail for so many bloggers and mentioned in nearly every youtube video on korean bb creams~ they promised a matte finish and is refreshing for oily skin, so i gave it a try. They were right about both but staying power ain't the best - i used a primer and finishing powder but it still shifted a round my nose and forehead in 3 hours. This is summer though, i look forward to seeing how it will perform in the dryer winter months.
