Green Tea: Healthy Skin with Benefits Did you know drinking 2-3 cups of Green tea could radically improve your skin, fight dementia, and keep allergies at bay? Green tea is naturally rich in catechin, a powerful antioxidant. Splash some lemon juice in your cup and the vitamin C will synergistically maximize your body’s ability to absorb those free-radical fighting goodies. Applied topically, it boosts sun protection factors. I use Osmosis Skin Care at the Sanctuary Day Spa (formerly Skin Therapy by Errin). Each facial ends with the application of Shade, a physical sunscreen enhanced with green tea extract. Should you choose Green tea over Black tea? Yes! Green tea is.
