Tomatoes, lemon, baking soda and honey offer the most effective home remedies to treat blackheads, according to Medindia. Tomatoes and honey have natural antiseptic properties, while lemon and baking soda act as the best cleansing agents.
Apply peeled and mashed tomato over the blackheads before going to bed, and wash it the next morning, states Medindai. Gently massage the affected areas with honey, leave for 15 minutes, and then clean it with warm water. Apply the mixture of lemon drops and salt, and allow it to dry for 20 minutes. Alternatively, you can use a paste made out of baking soda and water. Wash your face with warm water before and after application of these face masks, for an effective cleansing of dirt and oil that cause blackheads.
