Waterproof Bronzer

Hourglass cosmetics has come out with a Sephora-exclusive bronzer called the Supernatural Waterproof Bronzer. Am I the only one that's a little skeptical about a powder being waterproof? It's billed as being "an extended-wear, waterproof bronzer that withstands high humidity and extreme moisture. Supernatural is the go-to bronzer for swimming, outdoor activities, and the summer heat." Just the thought of having makeup caked on my face to the point where it will withstand a dip in the pool freaks me out. On the other hand, check out the amazingly cool swivel mirror. I can't even count the times I've unsuccessfully tried to twist my head at odd angles to see my face in a compact mirror so I could apply makeup--with this compact, I'd look like a pro!
