How about hydrogel mask? What's the difference with other masks?

Hydrogel mask is actually very popular in Europe, America and South Korea. After the essence of traditional facial mask is used, the amount really absorbed by the skin is less than a little, mainly because the skin barrier evaporates the original solution, which will lose a lot of essence. The essence of hydrogel mask is slowly decomposed and absorbed by gel-like solid, and will not be absorbed and evaporated. The Insimeiles mask I have been using is hydrogel.
