Tomato, lemon or any citric fruit make great natural exfoliates. They work as a natural sloughing treatment, removing dead skin cells from clogged pores. Firstly, wash your face and then rinse. Squeeze a lemon or citrus fruit into a bowl and soak a cotton ball in the juice. Apply the lemon juice to the face and then leave for 10 minutes before rinsing with cool water. The lemon juice may make your face feel like it is burning or tingling so if you have sensitive skin you might want to dilute the juice with some water.
