We've mentioned moisture a couple of times now, and how easy it is for lips to lose it, so let's go ahead and talk about how lips can get some of that lost moisture back. The best way is for you to stay hydrated. That means drinking lots of water -- generally about eight glasses a day -- to keep you moisture levels balanced. Remember: If you feel thirsty, you're already dehydrated.
Sometimes however, especially on cold wintery days, drinking water isn't enough to stave off dry lips. Heated indoor air can get really dry, too, so it's a good idea to set up a humidifier. Maintaining a 30 to 40 percent indoor humidity level during the winter months will help keep you comfortable in your skin, and putting moisture back into the air mechanically can help rejuvenate even the driest lips.
