Gwyneth Paltrow has never been shy about her off-kilter beauty regimen (she proudly gets vagina facials, after all) and her experimentation with voluntarily letting bees sting her in no exception. "It's a thousands of years old treatment called apitherapy," Paltrow told the The New York Times. "People use it to get rid of inflammation and scarring. It's actually pretty incredible if you research it. But, man, it's painful." Err, we'll stick to hydrocortisone cream, thanks. Photo: Getty

"If I wake up looking tired and puffy, I fill a sink with ice and cucumber and submerge my face," Kate Moss once said in an interview with Stylist. "It tightens everything, making you look and feel instantly awake. It is a bit Joan Crawford–but it works!" Having given it a go ourselves, we can personally attest to the frost-bitten glow it provides as the plunge improves skin tone, shrinks pores, and de-puffs. Photo: Getty

Eva Longoria, who is 41 but manages to not look a day over 25, swears by using cream infused with...wait for it... placenta. The natural afterbirth substance is said to promote collagen production and increase skin elasticity for a more sculpted appearance. Photo: Getty

The secret to Gabrielle Union's fountain of youth is that in her mid-30s, she began drinking a *GALLON* of water a day for glow-y, hydrated skin. Her pro tip? Drink as much as H2O as you can in the morning: "Try to drink half of it by noon and then just casually drink the other half until 6:00 p.m—after then it gets a little tricky," she told Elle.com.

Celebrities are *all* about a good, long shvitz. Especially if it's in an infrared sauna, which uses electromagnetic light (without harmful UB rays!) to penetrate the skin at a cellular level. This maximizes the cleansing process, yielding the most squeaky-clean complexion you can get. "It just allows for such beautiful, glowing skin and cell rejuvenation and detoxification," Jennifer Aniston told Forbes. "It even helps with weight loss and relaxation." Photo: Getty

After traveling to Japan and marveling at the local women's incredible skin, Victoria Beckham went all I'll have what they're having and started tapping into the ancient Japanese tradition of getting a facial infused with bird poop. The unsavory ingredient is actually powdered nightingale droppings, which Geishas would use to brighten, smooth, and soothe skin. Photo: Getty

Kim Kardashian will stop at nothing for ultimate beauty, but perhaps the most notorious of all the treatments she's tried is the "Vampire Facial." A non-surgical alternative to a face lift, it consists of injecting a jelly-like substance into the face made from the patient's very own blood. Photo: Getty
