In hot summer, I feel that my skin is prone to lack of water, especially oily skin like me. When water is scarce, my face will be shiny. At this time, the least we can do is to use masks! Sometimes when I put on a mask, I always wonder if time will pass. However, if you are busy, you can leave it alone for a minute or two, and don't leave it for too long! The hydrating effect is great!
