Very nice mask. I bougth four units and I used one each week. My skin usually has some oil so mask and products with green tea is a good option to control this problem. It is very easy to use, like a regular paper mask. The fragance is nice, not strong.  I leave it aproximatly around 15-20 minutes in my face. When the time os over, I dont wash my face or clean it, I just leave it until it is absoved by my skin. I felt my skin soof and mousturized. It is bringing with a lot of product.
