This is the Yuja Sleeping Pack, and you can just go to sleep after applying it. It is a leave-on sleeping pack. Since it isn't a peel-off type, it is incredibly convenient to use. The name is the Yuja Pure Cotton Pack, and the scent is actually quite strong, like the yuja itself. So, if you dislike strong scents, this product might not be suitable for you. However, I like the yuja scent and don't mind having a fragrance on my face, so I just apply a generous amount before going to sleep. After sleeping with it on, my face definitely feels a bit glowy and brighter. Also, my skin texture feels very soft. I'm writing this post because I think it's pretty good, haha. Perhaps because it contains a lot of Vitamin C, it definitely seems to have a whitening effect. While most brightening products aren't strictly "full-scale" brighteners and tend to be a bit irritating to the face, this one is very gentle. There is absolutely no irritation.
