15 Minutes Later I started to feel the pulling about five minutes in. I had been warned by a representative from Hanacure that the mask works best if you don't crack it, so I tried my best not to move my face . . . but I don't think I could have even if I wanted to. My skin felt like it was sucking into itself. My lips were puckering outward involuntarily. Closing my eyes all the way hurt. Image Source: POPSUGAR Photography / Maggie Pehanick
