Your guess is as good as mine. Well, I suppose I actually looked at the product long enough to snap a picture so maybe my guess is actually better than yours. From what I gather, these KOGAO masks are for people to wear and shrink their faces. Why shrink your face? Because then of course you will be more beautiful, you fathead. I suppose this could maybe possibly perhaps work, but come on. I’m sure results aren’t dramatic. Also note that these aren’t only for womenfolk; the gray one on the far right is for men. I imagine this is something so ridiculous you could only find in Japan.

Here’s a closeup of the pink sauna mask. It’s okay to be scared.
