Saw this on tiktok, and was told it was virtually magic. I was skeptical, because in 40 years, nothing has worked on my skin under the best conditions, much less when it's hot, humid, and nearly a hellscape. But I tried it anyway. While it hasn't become a true hell yet, I tested it at work, pouring sweat *and* in a mask. I got home, still had makeup on, and shockingly, even my eyeliner was still where I put it. Even where my mask was, I still had foundation. This stuff is what I have been looking for all my life.
