Double cleansing is enough but then it only sweep away the dirt and makeup residue and the next skincare routine like toner, serum, moisturizing, sleeping mask and more would provide more vitamin for your skin all night. So then you will find your skin much better in the next morning, and this last couple of months I use a moisturizing toner by COSRX. As I found on an article that extract of centella asiatica could increase the level of skin’s natural oils so that moisture and skin elasticity can be maintained.
