Moore recently told Letterman in an interview that she went to Austria for a leech treatment to "cleanse" and "detoxify" her blood.
But don't look for leeches on your local spa menu any time soon. "We all know leeches have been around for centuries. The 19th century approach was we will draw the toxins out of you with a leech, but nowadays spas have much more sophisticated methods of achieving that. So you would be hard-pressed to find an American spa offering leeches. … I'm just not seeing that," said Gelula.
After nightingale droppings, bull semen and leeches what could possibly be next?
How about a mani/pedi with some skin-eating fish? Garra rufa fish, or "Doctor Fish," eat dead skin and have been used in European and Asian countries for years to nibble the epidermis of patients suffering from psoriasis.
In 2006, the Ooedo-Onsen-Monogatari spa in Tokyo started offering a "Doctor Fish" spa treatment at its hot springs bath. The spa claims the fish will nibble your dead skin cells and leave your skin feeling smooth.
And if those smooth hands are looking a little too "old" for your liking, don't worry, because cosmetic surgery has just the thing -- hand deveining.
Some women who have treated their faces cosmetically to look younger, don't want to have their "ropy looking" hands give their age away, according to Neil Sadick, a clinical professor of dermatology in private practice in Manhattan. Sadick developed a laser procedure to get rid of hand veins that, apparently, aren't all that important.
"Hand veins don't play a vital role. … The only concern would be if you removed every vein in your hands and arms," said Sadick. And, if your deveined hands are still a little thin, said Sadick, cosmetic fillers can "add some volume."
Leslie Baumann, a professor of dermatology at the University of Miami, urges some caution for women and men seeking the next new thing in beauty.
Some beauty treatments may not work but some might actually be harmful. Take the current trend for gold leaf facials.
"I noticed Mar-a-Lago in Palm Beach started to do a 24-carat gold facial. It's a terrible idea. Gold can actually cause a lot of allergies and can lead to skin diseases. It can really be dangerous on your skin," said Baumann.
Dangerous or not, it's doubtful people will put the brakes on their willingness to try anything that promises to make them look more beautiful any time soon.
"People want to chase the next new thing without caring about the data. Retin-A is still the only anti-aging skin care cream approved by the FDA [Food and Drug Administration] but people don't want that. … They would rather spend some $300 on some lily extract from Ecuador. They bind to the story more than the science," said Baumann.
And, when it comes to beauty, a story about nightingale droppings, bull semen and skin-eating fish beats out science every time.
