We're down to clown with half of Hollywood claiming their lips are injection-free. But we draw a line at the bogus skin claims. No one has ever slept her way out of acne (or hyperpigmentation, or rosacea, or dry skin). Here are three things celebrities always say they do that are big, fat lies.

The lie: "I drink 400 bottles of water a day to hydrate my skin and flush out toxins."

The facts: The most clichéd tip in Hollywood is also the biggest myth. "There's absolutely no data to support the claim that drinking a ton of water will hydrate your skin," says Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital. "Sure, your body will thank you for it, but it's not going to revitalize your skin or flush anything away. Your skin isn't a cleansing organ."

The lie: "I sleep ten hours a night, which is why my skin looks so good."

The facts: OK, there's some truth to this one. When you don't sleep, your cortisol levels stay raised, which can mess with your hormones and promote acne, says Zeichner. But that doesn't mean that a few nights of shut-eye will leave you looking like Cate Blanchett on Oscar night. Sorry.

The lie: "I cut out [insert food group here] for a week, and my acne completely disappeared!"

The facts: Nope. Just nope. Assuming you have no food allergies, "eliminating one thing from your diet won't regulate your hormones or hair follicles or oil production, especially in as little time as a week," says Mona Gohara, an assistant professor of dermatology at Yale School of Medicine.
