Odds are it’s no more ‘beautifying’ than slapping egg whites on wrinkles.
When egg whites dry, they ‘tighten’ making the wrinkles less visible.
It doesn’t make them go away, however.
Snail slime dries like that, too.
I think this is a marketing ploy for absolute suckers.
“I can feel it working!”
Not if you get to take them home and saute them. After a day of purging, of course.
