This is my fourth time using this product. What's so good about it? I'm not sure, but continued use seems to restore firmness and radiance to the skin. It doesn't work on existing blemishes, but it does tone the skin and make them less noticeable. If I'm going to continue using HAKU, I'm sure this product will definitely make my skin clearer. However, it's quite expensive. But since you only need a small amount, it's pretty good value for money, so I tell myself that it's a good value, and I buy it when I get a lot of points back.
