What is Hydrogel?
A hydrogel is a network of cross-linked polymer chains that are hydrophilic, sometimes found as a colloidal gel in which water is the dispersion medium. hydrogels are highly absorbent (they can contain over 90% water) natural or synthetic polymeric networks.
(According to Wikipedia)
What is a Hydrogel mask?
A hydrogel mask is a skincare mask formulated with hydrogel. Unlike the traditional sheet masks, the Hydrogel mask has a unique formula like jelly full of essence. The hydrogel can hold a large amount of water and prevent its evaporation. While naturally melted by the skin temperature and absorbed into the skin, hydrogel fully transfers the active ingredients and the moisture contained to the skin.
