9. Lemon Juice
Lemon juice is a wonderful treatment for chronic acne as it is far less drying than conventional acne products. Take a slice of fresh lemon, and rub it over problem areas taking care not to get the juice into your eyes. Leave for 10 minutes, and then rinse with cold water. Alternatively, you could make a paste with lemon juice and baking soda, and apply it to individual pimples as an overnight treatment.
