Across the U.S., people — OK, mostly women — have been rushing to their local spas this week to receive some weird and wacky treatments, from procedures first devised by NASA to face lifts that don't require going under the knife.
Behinds are looking extra fine, thanks to facials targeting the rear end, and some treatments are so good, you could eat them — literally.
Even better, these treatments come cheap. Much like the "restaurant weeks" hosted in major cities, where diners get to try culinary delights at a lower flat rate, SpaWeek participants can pamper themselves silly with a variety of treatments for only $50. In some cases, this can be a savings of more than $125.
FOXNews.com took a look at some of the more interesting treatments available. To check out spas near you (there are still three days left) go to spaweek.org.
Top 7 Weird Treatments Offered During SpaWeek:
1. Sweet Cheeks Derriere Facial, Euphoria Spa
Whenever women go for a facial, they expect the treatment to be on their cheeks — of their face, that is. But at Detroit-area spa Euphoria, the facials apply to the other set of cheeks — the ones you sit on.
"We always try to come up with different ideas for services and I just hadn't seen it," said spa owner Lisa Johnson. "And that's an area that never gets the treatments it needs. It's like, 'Don't touch the goods.' We sampled it on a staff member to make sure clients would feel comfortable."
Johnson said clients are still covered up as they have their derrieres cleansed and exfoliated. Then a masque is applied and any waxing, if needed, is done. The treatment ends with a warm paraffin treatment.
"The [biggest] problem with it is that people are so apprehensive. But once they get it, they're like, 'Oh my gosh, that feels so good.'"
Johnson said the treatment is available to both men and women, but so far, men haven't taken to it.
Regular price: $65. SpaWeek: $50.
2. New York Post Page Six Facial, Aqua Vitae Spa
Named for famed gossip column Page Six, which runs daily in the New York Post, this customized facial gives the spa-goer a specialized treatment that focuses on the client's particular needs.
Spa director Isabel Sutherland says the Manhattan spa has no connection to the Post's gossip column, except for the fact that clients who have this facial might want to look like the celebrities it chronicles.
Of the seven treatments listed here, this is the one I was able to experience for myself. It was my first-ever facial, and I can say it was interesting — and more painful than I expected (I had no idea so much stuff could live in my pores!) But the Dead Sea mask felt great, and when it was all said and done, I definitely noticed a difference.
Sutherland tailored my facial to help tighten my pores and give my face muscles some extra lift. Aquavitae also offers a special light treatment called LumiLift. Originally used by NASA to heal injured astronauts, this treatment lifts collagen to the skin's surface. (Note to other facial newbies: Do not get one on the day of a special event — your skin tone looks uneven afterward. However, the next day, you look amazing.)
Regular price: $125. SpaWeek: $50.
3. Caviar Spa Pedicure, Spa Newbury
Some prefer caviar on a cracker. Some prefer it with a little lemon juice and a sip of champagne. And some prefer it rubbed all over their feet.
No, this isn't a weird fish-egg foot fetish. Rather it's a treatment offered at Spa Newbury, where clients have their feet smothered in products enhanced with fish eggs to help replenish their skin.
Boston spa owner Selena Belise said the treatment includes a "marine collagen, similar to the skin's own chemistry, so it binds the skin and brings nutrients ... that are missing."
Clients first experience a scrub with an exfoliant and then they receive a foot mask, followed by a massage. Regular price $100. SpaWeek: $50.
4. Chocolate Manicure, DeFranco Spagnolo Salon
After a caviar pedicure, spa-goers might want to finish off with something sweet, like a chocolate manicure.
Clients first receive a scrub to slough off dead skin as well as a hand massage. Then a mask is applied, leaving "your skin smoother and beautiful like a baby's skin," according to Nina Ibragimtchaev, spa director at the Great Neck, N.Y., salon.
5. Green & White Tea Sundance Body Facial, Eurasia Spa
We know green tea is good for the heart — but good for the skin?
Eurasia Spa marketing director Rebecca Hing says so. Her Scottsdale, Ariz.-based spa offers an award-winning green and white tea body facial that rejuvenates the skin with its antioxidants.
White tea — the "youngest" form of tea — is especially potent because it's so close to its most natural state and hasn't been processed. Green and white tea leaves are combined with ginger essence oil, unrefined sugar and shea butter.
"It's awesome," Hing said. "You basically want to eat it."
She recommends a Japanese soak beforehand to help the client relax.
Regular body facial price: $175/80 minutes. SpaWeek: $50/60 minutes.
6. Quantum Biofeedback Stress Reduction, VH Spa for Vitality + Health
Clients looking to reduce stress might at first experience more stress when they see the set-up for the VH Spa for Vitality + Health's Quantum Biofeedback Stress Reduction treatment, a procedure initially used to help with pain management.
At the spa, which is at the Hotel Valley Ho also in Scottsdale, clients have wires strapped around their wrists and heads and are hooked up to a computer that monitors their electric energy.
These impulses, according to spa director Brad Garret, "are translated into hormone levels, stress indicators, serotonin levels, liver and organ functions." Impulses are then sent back to the body to try to achieve balance in these various area, Garret said.
Best of all, the entire process is painless.
"Most clients just fall asleep," he said.
Regular price: $150. SpaWeek: $50.
7. Non-Surgical Face Lift, Platinum Skin Care
Are you in need of a lift but not at liberty to jet off to Mexico while you recuperate?
Platinum Skin Care's non-surgical face lift might be a good replacement. The Detroit-area skin care and medical spa offers what it calls a "low-frequency treatment to re-educate the muscles," according to spa director Dora Waylen.
An aesthetician wears gloves that deliver electric currents while massaging the client's face.
Regular price: $100. SpaWeek: $50.
Sure, it's nice to grow old gracefully, but there's nothing wrong with having a little help along the way. And — as SpaWeek highlights — you don't have to be in New York or Los Angeles to find these anything-but-normal services.
