No matter what type of skin you have, you need to moisturize it. This is another area where skin care myths abound. Some people think that misting skin with bottled or canned water counts as moisturizing, but when the water evaporates, it actually strips moisture from the skin. As with skin cleansers, you'll want to look for moisturizers made especially for dry skin. Dry-skin moisturizers typically contain emollients like ceramides, olive or mineral oil and petrolatum. These ingredients seal in your skin's natural oils while creating a protective layer on the surface. This barrier will prevent cracks and sores, seal out potentially harmful germs and viruses, and give your complexion a healthy glow.
