Dry lips? Here’s why you should avoid licking them
When your lips feel dry and tight, it’s tempting to moisten them with your tongue. It might bring a moment of relief—but in reality, it only makes things worse. Licking your lips can lead to even more dryness, irritation, and sometimes painful cracks. Here’s why that happens, and what you can do instead to keep your lips soft and healthy.
Why lips get dry
The skin on your lips is thinner and more delicate than the rest of your face. It doesn’t have oil glands to produce the natural oils that protect against dryness. That’s why lips lose moisture quickly, especially in cold, dry, or windy weather.
Indoor heating and air conditioning can also dry out your lips, as can frequent mask use or breathing through your mouth. Many people notice their lips get extra dry in winter, when humidity levels drop and the air both indoors and outdoors is drier.
Saliva makes it worse
When you lick your lips, you do add moisture for a moment—but saliva evaporates quickly. It also contains enzymes that help break down food, and those same enzymes can irritate the sensitive skin on your lips. The result? Your lips end up even drier than before.
The more you lick, the worse it gets. This can turn into a cycle where your lips always feel dry, so you lick them again and again. In some cases, it can lead to “lip-licker’s dermatitis”—a red, irritated area around the mouth that can be painful and slow to heal.
How to care for dry lips the right way
Fortunately, there are simple and effective ways to prevent and treat dry lips—without using your tongue.
- Use a moisturizing lip balm with ingredients like beeswax, shea butter, lanolin, or ceramides. These create a protective barrier that locks in moisture.
- Avoid products with menthol, camphor, or alcohol, which can dry out your lips and give only a short-lived cooling sensation.
- Stay hydrated. Sometimes dry lips are a sign that your body needs more water.
- Protect your lips from the elements. Use a lip balm with SPF in the summer and a thicker, protective formula in the winter.
- Don’t pick at dry skin or scabs. That can delay healing and increase the risk of infection.
If your lips are severely cracked or painful, a healing ointment with ingredients like panthenol or zinc oxide can help soothe and repair the skin.
Everyday habits that help
In addition to daily lip care, small changes in your habits can make a big difference. Try to avoid breathing through your mouth, especially while sleeping, and keep indoor humidity at a comfortable level. A humidifier in your bedroom can be a great investment during the colder months.
If you tend to lick your lips without realizing it, keep a lip balm handy—in your pocket, purse, or at your desk—so you can apply it whenever your lips start to feel dry.

When dry lips don’t go away
Most of the time, dry lips are caused by weather or habits. But if the problem becomes chronic, it could be a sign of something else. Certain medications, allergies, or skin conditions like eczema or psoriasis can cause persistent dryness and cracking. In those cases, it’s a good idea to talk to your doctor or a dermatologist to find the underlying cause.
The bottom line
Licking your lips might feel like a quick fix, but it only makes dryness worse. The best approach is to protect, moisturize, and care for your lips properly—not to rely on saliva. With the right habits and products, you can keep your lips soft, smooth, and comfortable all year long.
