Green tea tones can help reduce inflammation and redness, prevent acne and brighten your skin. Add a cup (240 ml) of water in a small pot to create your own green tea tones. Then boil the water. Step 1 Bag green tea in the boiling water for 15 minutes. Let the tea cool, then pour it into a glass spray bottle. Add 30 drops of lavender or tea tree essential oil, shake well and you're done! You can use two tablespoons (30 ml) of witch hazel instead of essential oil if you wish. If you want to use your green tea toner, spray it on your face after you wash it and let it dry.
