This 7-Day Green Beauty Challenge Will Make Your Skin Glow

The daily toxins you ingest dehydrate you, which can create dull skin and dark circles under your eyes. Want an easy way to brighten your glow? Divide your body weight in half, and that's how many ounces of filtered water you should drink.

If you are a coffee drinker, stick to one cup in the morning. And switch to either green or hibiscus tea for the rest of the day — both contain a high amount of antioxidants. Plus, hibiscus tea has been proven to lower blood pressure.

Your challenge: Drink half your body weight in ounces of filtered water daily.
