What is a one-sentence summary of the following article?
Your body naturally produces oils that keep your skin protected and prevent drying out. However, you do lots of things throughout the day that remove these natural oils. The biggest threat to your skin's natural protectant is your bathing routine. Soaps which remove to much oil from your skin and water which is too hot both put your skin at risk. Lower the temperature of your showers as low as you can stand and use only soaps which contain moisturizers or are marked for "sensitive skin". You should also be sure not to bathe too often or for too long. Both can also wash away too much of your natural oil. Shower for no more than 10-15 minutes and no more than once a day. If you can, bathe only every other day. You have probably seen the advice to exfoliate dry skin. This removes the dead skin, preventing infection and allowing moisturizing products to absorb properly. This is good advice but you should follow it carefully. You don't want to exfoliate too often, first of all. Once or twice a week can be plenty, especially for sensitive areas like the face. You also shouldn't use harsh exfoliants, like a loofah or pumice stone. Instead, baking soda paste or a clean washcloth will get the job done without causing damage. It is also important to make sure the washcloth you use is clean. One of the reasons why things like loofahs cause problems is because items like that easily harbor germs and bacteria. Using a clean washcloth can help keep that problem from happening. When you dry your skin, be careful. Vigorous rubbing with a towel can not only irritate your skin, it can also remove too much moisture and oil. This can cause dryness or make an existing problem worse. Instead, air dry when you can and otherwise lightly pat your skin dry with a soft, clean towel or cloth. After you bathe or get your skin wet, you should always apply a layer of moisturizer to help lock in moisture and return the natural oils that you may have removed. This basic layer does not need to be thick, necessarily. Just a basic layer of protection can make a difference.  Lanolin cream is one of the best products for protecting your skin and maintaining moisture. This is a natural product which is produced by animals to protect their own skin. The most common US brand is called Bag Balm and can be found in most drug stores. For your face, however, lanolin can be a bit much and should be used only occasionally and in very severe cases. Otherwise, you should use a lighter product which is oil free and designed not to block pores or cause other skin problems. If you can, try to apply a thicker layer of product at night, and then cover the area in clothing to protect the product. This will give your skin more to absorb and more time to absorb it. Be aware, however, than most of these skin moisturizing products stain, so be sure to cover the skin with clothing that you don't worry about, like an old pair of sweats or pajamas.

Summary:
Maintain your natural oils. Exfoliate gently. Dry your skin carefully. Apply a moisturizer. Apply a thicker layer at night.
