10 Ways to Green Your Beauty Routine

Sip Through a Straw

• Here's a trick we've learned from makeup artists: Drink through a straw whenever possible so you don't mess up your lipstick. Your pout stays perfect, so there's no need for a zillion touch-ups. That, in turn, means the tube lasts longer. Green the effort with a reusable glass straw.

Brush Up Your Act

Blow Off Your Shampoo

• Going a few days without washing your hair not only adds sexy texture that makes for easier styling, but also is good for the environment-saving water and electricity used for blow-drying. To keep strands from looking oily, Bishop suggests sprinkling dry shampoo near the scalp and tousling with your fingers.

Turn Off the Water

• Every minute the faucet runs, two gallons of water go down the drain; the average eight-minute shower dumps 17 gallons. To conserve, wash up with a biodegradable, rinse-free facial wipe, suggests Donna Bishop. "These remove buildup using less water, and they gently exfoliate." Or simply shave two minutes off your shower time (set a kitchen timer to keep track).

Be a Label Hound

• Check the ingredients, especially for products used on large areas of your body. Although conclusive evidence remains elusive, many consumer watch groups fear that chemicals such as parabens and phthalates may be toxic when absorbed in high doses. Another additive to watch out for: sodium lauryl sulfate, a common source of skin allergens. Though the FDA regards the doses in cosmetic products to be too low to cause harm, it can't hurt to limit your exposure to them, says Jenny Kim, associate professor of clinical medicine and dermatology at UCLA.

Make It Good Till the Last Drop

• Squeeeeeeze every ounce out of your products. A wringer, like those made for caulking guns or paint tubes, does the trick. Turn your last bits of eye shadow into eye-liner by applying with a thin brush dipped in Visine. And if your mascara dries up and gets clumpy, run hot water on the outside of the tube to re-liquefy.

Get Rewarded for Recycling

• You've scraped the last shred of blush from the container-now what? Bring back empties (from any brand) to Origins stores for recycling. Drop off plastic caps, like the hard, ridged ones on soda bottles or toothpaste tubes, at Aveda stores, where they'll be used to create new caps. (Many local recycling centers toss them out because they're so tricky to melt down.) Or accept a little (well-intentioned) bribe: For every six empty MAC containers you return, you get a free lipstick.

Go Green With Color

• No need to sacrifice performance for an eco-friendly polish. The formaldehyde-and toluene-free Zoya line comes in vibrant shades and stays put for a week (even after washing dishes, trust us). For commitment-phobes, nontoxic water-base polishes like Sula Beauty's are a great alternative—simply peel them off when you get bored; no remover needed.
