Beauty 101: The Ultimate Skin Cleanse

Myth: Juice cleanses and detox diets can solve all your skin problems.

Truth: Our bodies are designed to eliminate toxins; eating extra kale isn’t going to clear up acne, says Gina Sam, a gastroenterologist in New York City. But studies suggest that eating antioxidant-rich foods can help mitigate UV damage to the skin.

Myth: Drinking your weight in water will flush out toxins and improve your complexion.

Truth: A 2010 study found no scientific proof that drinking water made skin more hydrated, less wrinkled, or healthier. But it will quench your thirst!

Myth: You can sweat out pollution and booze.

Truth: Sweat doesn’t eliminate toxins from your body. Perspiration is 99 percent water, 1 percent minerals and other stuff, and 0 percent tequila and salty bar snacks. That said, exercise does increase circulation in the skin to make it glow-y and lower the cortisol in the blood that can cause wrinkles and laxity.
