Add four drops of tomato juice to 1 tablespoon of water and apply it on your face with the help of a cotton ball. Gently massage your skin with this mixture and leave it on for 15 minutes. Regular application of this will shrink the pore size. You can also stew tomatoes to prepare tomato soup, sauce, and other baked dishes. Homemade tomato sauce is way better than those available in the market.
