Drinking water can change your skin tone.

I've found that filling your insides is more important than applying expensive cosmetics. One habit I've been consciously practicing since last year is "drinking two liters of water a day." At first, I wanted to give up because going to the bathroom was a hassle, but after about a month of consistent practice, I can definitely see my complexion clearing up. Whereas my skin used to be dull and yellowish, it now feels clear and transparent.

Drinking warm water or decaffeinated tea instead of coffee regularly helps flush out toxins from my body. It's especially important in the winter, when heaters can easily dehydrate us, so I'm especially careful about what I drink. Having experienced how simply drinking water can help alleviate some of my dry skin, my tumbler has become my lifeblood. For your skin, start by drinking water.
