Why Are My Lips So Dry? Five Causes of Dry Lips
Do you often ask yourself, “Why are my lips so dry?”
The delicate skin on your lips doesn’t contain oil glands and is naturally dry. However, vitamin deficiencies, sun exposure, dehydration, and harsh temperature can cause excessive dryness and lip licking, quickly leading to cracked lips.
Learn why lip balm isn’t the best option to treat dry lips and how to heal chapped lips naturally.
Five causes of dry lips
Lips are naturally dry as they don’t contain sebaceous glands, which secrete oils, wax, and cholesterol that keep skin moisturized and protected.
Lips also have a much thinner layer of skin than the rest of the body, making lips more susceptible to dryness and irritation.
While occasional dry lips are typically nothing to worry about, severely chapped lips can be painful and irritating and may be a sign that your body lacks essential nutrients.
Here are five common causes of dry lips.
1. Nutrient deficiencies
Healthy skin—including lip skin—requires several nutrients, including vitamin B2 and zinc.
Vitamin B2 plays a vital role in the renewal of skin cells and is involved in producing moisturizing factors that keep lips hydrated. Lack of adequate vitamin B2 is one of the most common causes of dry lips.
Vitamin B2 deficiency can develop due to excessive alcohol consumption, birth control medication, and a high-carb diet causing an increased vitamin B2 turnover.
Zinc, on the other hand, is an essential mineral needed to maintain the integrity of the skin barrier, prevents fluid loss and dryness, and is crucial for skin repair and regeneration. Zinc deficiency can prolong the time it takes for chapped lips to heal.
While zinc is found in many foods, a high-grain diet can significantly increase the risk of zinc deficiency. Most grains contain several anti-nutrients, including phytic acid, that inhibits the gastrointestinal absorption of zinc.
2. Yeast infections
In some cases, persistently dry and irritated lips may be caused by oral yeast infections.
Research published in PLOS ONE found that oral thrush, typically linked to Candida yeast overgrowth, can trigger inflammation and cause painful cracks at the corners of the mouth, which can lead to lip dryness and discomfort.
Yeast thrives on sugar which explains why a high-carb diet, in combination with weak immune defenses, increases the risk of yeast and fungal infections.
3. Dehydration
Without adequate hydration, the integrity of the skin barrier can become compromised, which allows moisture loss and makes lips more susceptible to dryness and cracking.
“In most cases, dehydration is linked to an imbalance of electrolytes such as sodium and potassium,” explains Dr. Berg. “Potassium plays a vital role in maintaining fluid balance and keeping body tissues hydrated. Lack of adequate electrolytes can affect the moisture levels in lips and lead to dryness.”
4. Sun exposure
Prolonged exposure to ultraviolet (UV) radiation emitted from the sun can damage the delicate skin on your lips.
Excessive UV radiation has been found to trigger the breakdown of skin collagen and elastin fibers, which disrupts the integrity of lip skin, increases moisture loss, and impairs skin cell renewal.
5. Cold weather and dry air
Cold weather conditions and low humidity increase the risk of dry and flaking lips.
Cold and dry air contains less moisture which exacerbates fluid loss from the skin, including the lips. This explains why cold and dry weather can cause chapped lips.

How to get rid of chapped lips
To prevent and get rid of chapped lips, it’s crucial to address the underlying causes rather than reapply lip balm several times a day.
In fact, many products advertised as moisturizing lip balm contain petroleum jelly, a mix of mineral oil and waxes.
Research published in Gastroenterology found that mineral oil can lower cellular concentrations of nutrients, which may worsen chapped lips caused by nutritional deficiencies.
Most lip balms also contain synthetic preservatives that can cause irritations and break down the natural barrier function of lip skin, leaving your lips prone to dryness and chapping.
Here are five natural remedies for dry and chapped lips.
1. Nutrient-rich diet
Consuming plenty of foods rich in vitamin B2, including egg yolks, organic dairy products, nuts, and green leafy vegetables, can support healthy skin barrier function and stimulate the regeneration of skin cells.
To promote the healing of chapped lips, increase your intake of zinc-rich foods such as oysters, shellfish, meat, fish, dairy, and nuts.
In addition, eating grains and sugars depletes nutrients, including vitamin B2 and zinc, and switching to a nutritious low-carb diet like Healthy Keto® can be an excellent choice to keep lips hydrated and soft.
2. Aloe vera
Aloe vera has soothing and moisturizing properties that protect lip skin from harsh weather conditions and may help to heal chapped lips.
Applying aloe vera to dry lips minimizes the urge to lick your lips and relieves dry and irritated skin.
3. Hydration
Staying hydrated is vital to heal dry lips. However, just drinking water may not be the best way to stay hydrated.
Lack of adequate potassium intake is widespread, and potassium deficiency can disrupt the body’s fluid balance despite drinking plenty of water.
Increase potassium-rich foods such as avocados, spinach, beet greens, and broccoli, or consider taking a high-quality potassium electrolyte powder.
4. Manage potential yeast infections
Yeasts thrive on a high-carb diet, and avoiding refined carbs and sugars is one of the most effective ways to kill Candida and other yeasts.
If you suspect that your dry lips may be linked to a yeast infection, there are several natural remedies, such as garlic, thyme oil, or medium chain triglycerides (MCT), with potent anti-candida effects.
5. Sunscreen
If your lips are prone to sunburn, applying sunscreen to protect your lips' delicate skin from potentially harmful UV radiation can be helpful to minimize sun damage and dry lips.
How long does it take for dry lips to heal?
How long it takes for dry lips to heal depends on the severity of dry lip skin and the underlying cause.
While most cases of chapped lips can improve within a few days, more severe cases of cracked, irritated, and bleeding lips can take one to two weeks to improve.
If you suffer from chronic chapped lips or persistent cracked corners of the mouth that won’t improve, it’s crucial to consult a dermatologist to evaluate potential underlying causes and formulate an appropriate treatment plan to heal your lips.
Key takeaways
Nutrient deficiencies, dehydration, electrolyte imbalances, sun exposure, or harsh weather conditions are often the reason why your lips are so dry.
Rather than using lip balms that may worsen your dry lips, it’s essential to address the underlying cause of dry lips.
Staying hydrated, replenishing electrolytes, and avoiding refined carbs and sugars promote healthy skin barrier function and can help to heal cracked and dry lips.
