"Why are my lips so dry?" is a question I'm constantly asking myself as I apply another layer of lip balm to my painfully cracked, chapped lips

That said, it goes without saying that I'm definitely familiar with the tight, burning sensation that comes with dry lips, but I'm not 100 percent clear on what causes them. Sure, chapped lips are more common during winter when temperatures drop and there's less moisture in the air, but are any other triggers?

While the weather is a major factor, it's just one common cause of chapped lips. Believe it or not, lifestyle habits and the products you use on your lips can also be to blame. 

In the hopes of getting through this season smooth-lipped and care free, I turned to two dermatologists to find out exactly what causes chapped lips, the best treatments for dry lips, plus how to prevent them. 

What Are Chapped Lips? 

Chapped lips are a result of excessive dryness, usually brought on by a compromised skin barrier. The skin can crack and in severe cases, scab up. Damage to the skin barrier is often caused by changes in air humidity or exposure to irritants. "A dysfunctional skin barrier can cause the lip skin to turnover abnormally or incompletely, resulting in sheets of dry skin or even painful fissuring," says Dr. Melanie Palm, board-certified dermatologist and director of Art of Skin MD in Solana Beach Calif.

What Causes Chapped Lips? 

The weather is most prevalent cause of chapped lips. Changes in temperature and humidity, along with extreme UV exposure can all dry out or irritate lips. 

But licking your lips can also make them chapped. "When you try to remove dead skin and bite it off, you make the chapping worse," explains Dr. Joyce Davis, board-certified dermatologist in New York City. "In children, lip licking is common and may cause chapping of the lips and surrounding skin. When chapping is at the corner of the mouth, if is often due to mixing of the mouth saliva irritating this area, and this is most often seen in adults." 

And if you're using the wrong products, chances are you're making things worse. "Topical lip products, cosmetics (gloss, lipstick) and oral care products (mouthwash, toothpastes) all may irritate or dry the skin, resulting in dry, chapped lips," says Dr. Palm. 

What Are the Best Treatments for Chapped Lips? 

If your lips are mildly dry, Dr. Palm recommends using a sugar-based exfoliating scrub, followed by a bland lip moisturizer. Fresh's cult-classic Sugar Lip Polish Exfoliator gently buffs skin and has nourishing ingredients like shea butter and jojoba oil to help re-hydrate lips. 

When looking for a moisturizing lip balm, look for emollient ingredients like hyaluronic acid, glycerin, ceramides, squalene, and petrolatum, which all help repair the skin barrier. 

For severely chapped lips, Dr. Davis suggests first using an over-the-counter cortisone cream to calm inflammation. But it's important to use it sparringly. "Cortisone is not for long term use, since it can thin the skin," she says. "Once the lips improve, put it away until you next need it." If the chapping is at the corners of your mouth, you may need to see a dermatologist for a prescription topical product or cortisone shot.

How Can You Prevent Chapped Lips? 

Regularly wearing a moisturizing lip balm that contains SPF is the most effective way to prevent your lips from getting chapped this winter, along with occasional exfoliation. 

Avoiding products with irritating ingredients is also key. "Swelling, redness, and eventually dry, chapped lips can result from products that contain common irritants such as fragrances, cinnamates (cinnamon like chemicals), and certain dyes or preservatives," says Dr. Palm. If you have sensitive skin, pay particular attention to products in your lip products and consult with a dermatologist if a persistent chapped lip is occurring."
