I bought itfrom Sofina shop located at Maritime Square. It is a self-foaming facial cleanser and ease to use. It's no doubt that the foam is easy to be handled during the face washing process. However, I personally feel uncomfortable on 2 things: 1. This self-foaming cleanser is only for a month (2 times a day use) and HK$220 for a month's supply seems a bit costly to me. 2. I personally think that the self-rising foam is not that smooth in texture. After cleaning, the face is also not that smooth in texture. Thus, I don't think this item will be repurchased by me.
