“The skin under the eyes can get super dehydrated [due to] lack of sleep, inadequate water intake, sun exposure, aging, or even just a poor skin care routine,” explains Kristin Gunn, a celebrity aesthetician and the owner of Halcyon Skincare and Beaux Medspa. Korean eye patches not only combat dehydration, but they’re also effective at firming the eye area and reducing the appearance of wrinkles. When combined with the cutting-edge technology of the best Korean skin care brands, you have amazing patches that deliver results comparable to your favorite Korean face masks.
