Even if you're not a betting man, it's hard not to gamble on the fact that everyone's “beauty secret' is that they drink loads of water—or maybe lemon water. To prove the point, we gathered every water-related tip from every Top Shelf, After Dark, and The Face. By the end of the exercise, there were 14 pages of quotes. Here we've shared the more intriguing of the bunch—and categorized them, too. Enjoy and stay hydrated, kids.

Drink More Than You Think You Should

Michelle Monaghan: “In terms of what I eat, everything's pretty healthy. I drink so much water—at least 3 liters a day.”

Domino Kirke: “I have chronic dry skin. I went to a dermatologist and found out it was more about hydration, like drinking water. I was putting on the most expensive, thick, goopy stuff, but it just wasn’t sticking. I feel best when my skin is soft.”

Rose Bertram: “I used to have a problem with getting bags under my eyes, but I drink a lot of water now, which really helps.”

Cindy Crawford: “I mostly drink water because there are a lot of hidden calories in drinks.”

Wash Your Face A Little More

Charline De Luca: “One thing I do every night that might sound a little weird, but I can't get over, is that I wash my face with chilled water seven times—just out of the tap. The shock of the cold water on skin tones it. I do this after I cleanse. I don't know why seven, but I heard it should be seven, and I've been doing it day and night ever since.”

Occasionally Be Wary Of Tap Water

Claudia Kim: “I also try not to use tap water on my face—especially when I’m traveling. I’ll use bottled water to rinse instead. It just seems safer to me.”

Katie Nehra: “Not to keep ragging on LA, but the water here is tough for your hair. I did one of those water test with the drops, and LA water is five percent acid. I’m not crazy—LA water will turn your hair green, so I have a special filter on my shower.”

But Not Too Wary

Isamaya Ffrench: “Honestly though, for removing body paint, your best bet is just soap and water.”

Charlotte Tilbury: “I always wet the cotton pads with water, squeeze them, and hold them on my skin to let it soak, melting the makeup off. This way, I’m not just dragging my eyes around my face, and I won’t end up looking like a bag.”

You Can Be Clean And Also Environmentally Friendly About It

Athena Curry: “I usually take a shower because I don't like going to bed with makeup on my face. Because we're in LA and going through a drought, I have a little red bucket that I throw in the shower before I get in, so that it captures all my water as it's heating up. Then I use that water on my flowers out in the yard. I fill up a bucket every time.”

Consider Steam

Hannah Sider: “I like to use really hot water to steam my face and then splash some cold water on afterward.”

Sheila Marquez: “So first, I wash my face. Then I bring a pot of water to boil and sprinkle in a handful of the loose leaf tea. Then I take the water off the heat, drape a towel over my head, and stick my face over the steam for about five minutes. It makes your pores feel open and detoxed.”

Mix It With Things

Andrea Mary Marshall: “If you put it in a spray bottle, with equal parts vinegar and filtered water, and spray it on your head every day after you shower, your scalp will have a perfect pH balance. I massage it in and just dry my hair normally.”

Camilla Blackett: “[My hairstylist] taught me how to make my own tea tree oil spray with pure tea tree oil and water—20 percent oil, 80 percent water. If I work out first thing in the morning and have to go straight to the office, I’ll just spray the mixture into my roots, and I'm good to go.”

Sidney Williams: “Yeah—me and my friend India would put hydrogen peroxide and a little water in a bottle and spray it on our hair right before we went surfing.”

And Keep In Mind...

Diane von Furstenberg, Book of Beauty:“You cannot have a healthy body without drinking a great deal of water. But remember, you can’t just drink a glass of water and tell a glass of water to please go straight to your skin and moisturize your complexion. Water has to be there all the time, doing what it does naturally in a healthy body.”
