Its usage is very simple: thoroughly clean your facial skin, take out the mask, apply it to your facial skin, let it sit for 15 to 20 minutes to allow the essence to be fully absorbed, then remove the mask and wash it off with clean water. And it can enhance skin elasticity, firm the skin and reduce fine lines.
