If you are worried about your dry lips, it is good to understand their cause , which helps in finding the right solution. In this article, we will discuss the most common causes of  lips dryness and simple ways to keep your lips soft and healthy.

Dry Lips Causes: Why Lips Become Dry and How to Treat Them

What Are Dry Lips?

Our lips become dry when the skin of our lips loses moisture because of which our lips feel tight, rough, and uncomfortable. In severe cases, lips become cracked and sometimes bleeds.

Common Causes of Dry Lips

1. Dehydration

One of the most common causes of dry lips is not drinking enough water. When our body is dehydrated, our lips show the first signs.

Dry mouth, thirst, dark-colored urine and dry and chapped lips are some common signs of dehydration.

Tip: Drink 8-10 glasses of water daily to stay hydrated.

2. Weather Conditions

Extreme weather can damage the moisture barrier of our lips. Cold winter air, strong winds, hot and dry climate , and excessive sun exposure are some common weather conditions that cause dry and chapped lips.

You should always use a lip balm with SPF and containing  shea butter, coconut oil, beeswax, and petroleum jelly to protect your lips from sun damage.

Use a humidifier during winter for add moisture to indoor air.

3. Lip Licking Habit

Many people lick their lips when they feel dry. While this gives temporary relief, saliva evaporates quickly and removes natural moisture from the lips, making them even drier.

Try to apply lip balm as soon as required instead of licking your lips.

4. Nutritional Deficiencies

Our lips become dry and cracked if we have a deficiency of vitamin B complex, iron, and zinc.

Eating a balanced diet with fruits, vegetables, whole grains, and protein can help improve lip health.

5. Allergic Reactions

Some lip products may contain ingredients that irritate our sensitive lips, like lipstick, lip balm, toothpaste, fragrances, and cosmetic products.

If your lips become dry after using a new product, stop using it and monitor the changes.

6. Breathing Through the Mouth

Those people, who frequently breathe through their mouth, especially while they are sleeping, often experience dry lips. This habit exposes the lips to constant airflow, because of which there are moisture losses.

7. Certain Medications

Some medications, like acne medications, antihistamines, some blood pressure medicines, and certain vitamin A derivatives, cause lip dryness as a side effect.

Consult your healthcare provider if you suspect that a medication is causing severe dryness on your lips.

8. Medical Conditions

Persistent dry lips are sometimes linked to certain health conditions such as thyroid disorders, diabetes, eczema, and sjögren's syndrome .

If your lips remain dry despite proper care, it may be good to seek medical advice.
