This isn't the only time you may have spotted KT Tape at work during the Olympics. Early in the Games, skiers were applying KT Tape to their face to protect themselves from PyeongChang's bitter cold. That's a use KT Tape doesn't necessarily recommend.
"We did not know or expect that it was going to be used on skiers' faces. That's not the intended use for KT Tape," KT Tape chief marketing officer Russ Schleiden told Thrillist. "We have not recommended, and we have not researched or tested using it for frostbite prevention or cold prevention."
It has, however, researched how Nagasu is using it for pain relief.
