The expensive, highly concentrated ingredients are one thing, but what I felt made them go even further was the fact that the mask was made with hydrogel. Unlike a traditional cotton sheet mask — where the essence quickly evaporates into the air — the jelly-like material of this mask slows down the evaporation process, giving my skin more time to take it all in. This means that the ingredients will penetrate deeper into the dermis since they don’t have the option of disappearing into the air.
