This budget-friendly option is actually one of the most popular sheet masks in South Korea (and it's one of our top picks, too). "N.M.F." stands for "Natural Moisture Factor," a substance naturally produced by the skin to help it retain moisture. Other standouts include organic humectants, as well as willow bark and witch hazel.
A Korean beauty cult favorite, these nifty masks come in 13 different varieties. The aloe option is especially great for soothing dry skin in the winter (not to mention sunburns, come summertime) — and at less than the price of latte, the price can't be beat.
