Is your spa safe? Check it out before you go

If your New Year's resolutions include improving your health, you may have already booked a spa appointment.

That's because a growing number of spas in the past several years have shifted from a focus on pampering to overall wellness, according to spa marketing and media company SpaFinder. Of course, you can still book a massage or facial. But you're now more likely to see options such as healthy sleep workshops, too.

If you want to make sure your goal doesn't backfire, however, experts recommend checking out your spa or medical spa as thoroughly as you would any doctor. That means asking lots of questions. The risks of failing to do so range from a minor nail infection to — in the extreme — death, as in the 2005 case of a woman who was administered a fatal dose of lidocaine for a hair-removal treatment by a physician connected to a Raleigh, N.C., spa.

"Anytime you feel your questions are not being answered correctly, freely and completely, walk," says Hannelore Leavy, executive director of The International Medical Spa Association, a professional organization focused on promoting quality consumer care. "This is your health."

Experts say the first step you should take to ensure the safety of your spa is a straightforward one — visit it. If you see anything that appears unclean or makes you uncomfortable, trust your gut, says Lynne McNees, president of the International SPA Association, a trade association with more than 3,000 members in 75 countries.
