We envy the South Koreans for their plump, dewy and moist complexions. The key step to achieving that? By constantly hydrating your skin and pumping it with sufficient moisture. While using a toner and serum that targets dehydrated skin is important, one great way to level up your regime is by using facial masks. Whether an overnight sleeping one or a sheet mask, they give your skin an intense boost of moisture so it looks fresher, healthier and more luminous. To help you get started, we picked out the best hydrating Korean face masks you need to try out.
