Kevin Mazur/Getty Images for MDNA SKINMadonna‘s new line of skin care products, MDNA, is now available in the U.S., and according to the Queen of Pop, the products are even more versatile than you might imagine.

Speaking to People magazine, Madonna says she uses her Chrome Clay face mask — which costs $120, by the way — on places other than her face. “I have used the clay mask on my butt,” she tells People. “Don’t you want soft skin on your butt? I mean, don’t a lot of people look at your butt? Your butt has an audience. At least one!”

As for why she wanted to create a skin care line, Madonna says it’s because of something nearly every woman has experienced.

“As soon as I liked a product it was discontinued. It always happens to me,” she explains. “When I liked a product they stopped making it. So that was really the germ of what started this whole process of why I wanted to create [this].”

Madonna’s luxe line is certainly a long way from the days before she was famous, when she had to turn to, um, questionable individuals to provide her with skin care.

“I remember when I lived on the Lower East Side [of New York City] and I really didn’t have much cash,” she tells People. “And there was a salon on 7th Street between First and Second Avenue and there was a girl in the back — and I know this is weird — but she was a heroin addict, and she gave amazing facials and I would go to her.”

“Skin was very important to me,” she adds. “And I always took care of my skin, even at a young age.”

MDNA is available at Barneys New York stores and online.
