Hydrogel facial mask is also called water condensation film. As the name implies, it has a powerful function of agglutinating water, and can continuously replenish water for the skin after being applied to the skin. At the same time, the hydrogel facial mask can be added with some effective raw materials to achieve the beauty effect you want. For example, after adding arbutin to the hydrogel facial mask, the facial mask is a facial mask with whitening effect.
