Tomato is considered as a natural bleaching agent and is very helpful in lightening the skin tone. Prepare a face pack by mixing 1 teaspoon of oatmeal, 1 teaspoon of yogurt and 2 teaspoon of tomato pulp. Apply it on the face and neck and leave it for 20 minutes. Oatmeal will gently exfoliate the skin, while yoghurt and tomato will help to clear the blemishes. This improves the complexion.
