Most people have experienced dry and cracked lips, which can be both uncomfortable and unsightly.

There are several reasons why your lips may be prone to dryness and cracking, so it’s important to understand the causes if you want to prevent and treat this condition.

1. Dehydration

One of the most common causes of dry and cracked lips is dehydration. When you’re dehydrated, your body doesn’t have enough water to keep your skin hydrated, including your lips. This can lead to dryness, flaking, and even cracking.

2. Cold Weather

If you live in a cold climate, you may notice that your lips get especially dry and cracked during the winter months. Cold weather can cause the moisture in your skin to evaporate more quickly, which can lead to dry and cracked lips.

3. Sun Exposure

Just like the rest of your skin, your lips can be damaged by the sun’s UV rays. Over time, sun exposure can cause your lips to become dry, chapped, and cracked.

Be sure to use a lip balm with SPF to protect your lips when you’re spending time outdoors.

4. Licking Your Lips

When your lips feel dry, it may be tempting to lick them to provide temporary relief. However, this can actually make the problem worse.

When you lick your lips, it removes the natural oils that protect your skin and can lead to further dryness and cracking.

5. Allergies

If you have allergies, you may notice that your lips get dry and itchy along with other symptoms. Allergic reactions can cause inflammation and irritation that can lead to dry and cracked lips.

6. Medications

Some medications, such as acne treatments and chemotherapy drugs, can cause dryness and cracking of the lips as a side effect.

If you’re taking medications and experiencing this problem, talk to your doctor about alternative treatments or ways to minimize the side effects.

7. Nutrient Deficiencies

If you’re not getting enough of certain nutrients, such as vitamin B, iron, or omega-3 fatty acids, it can lead to dry and cracked lips. Make sure you’re eating a healthy and balanced diet that includes a variety of nutrient-rich foods.
