The eye treatment makes me wonder if they forgot the disclaimers or we should now go and do that at home.
Bit of late reply, you probably won't see it but, it's 100% legit
BUT it's translation error, that's not technically butter but
ghee.
Indeed, they form a dough like "glasses" around eyes as a form and pour pure warm ghee, after it reaches body temperature you're supposed to open eyes for a minute or two.
It's scary at first, you might figure it may damage your eyes, but it's not only harmless but will soothen strained eyes.
Easier is just to use ghee rich balm around eyse once in a while, same effect, less
hipster "avant-garde".
