One of the key factors in the production of nose blackheads is excess facial oil. There are several ways that you can reduce the amount of oil your skin is producing. Before you start using harsh astringents and prescription dermatological medications, consider first trying something natural. Simply spend some time out in the sun each day. If you apply non comedogenic sunscreen and go out during the hours when the suns rays are the least harmful, you can safely dry up oil in your face. Plus, proper sun exposure gives your body the chance to absorb vitamin D which has been found to help produce healthy skin.
