This is a facial sheet mask from one of the most popular face mask brands Lululun. 
 
This lululun mask moisturizes your skin with a good balance, so it is thought for people who have dry skin and at the same time excess of oil in some skin parts.
 
It also hydrates your skin while it supports the potential function of skin barrier. 
Lululun suggests you "to mask lotion" everyday instead of putting it on with your hands. So they offer big quantities of face masks at reasonable prices. This small pack is for trying the first 7 days.
