This common condition occurs when dry or cracked skin on the lips prompts you to lick your lips. Licking temporarily alleviates the symptoms, but the saliva dries out your lips more, worsening the situation and perpetuating a cycle. Lip licker’s dermatitis typically looks like dryness, redness/discoloration, chapping, and scaling in a ring shape around the lip area.
This article discusses the symptoms, causes, and treatment of lip licker’s dermatitis.
Lip Licker’s Dermatitis Symptoms
Skin irritation can happen all over the body, including on and around the lips. Dry and cracked lips are common in colder months and dry climates, but many people experience them throughout the year.
The main symptoms of lip licker’s dermatitis typically show up in a circular formation around the lips and include:
DrynessScalingChappingInflammationRedness or discolorationPeelingCrackingCrusting
While these symptoms usually form close to the lip area, they can be visible as far as the tongue (and saliva) can reach.
Causes
The cause of lip licker’s dermatitis is repeated skin contact with saliva, which has digestive enzymes that can harm the delicate skin around the lips.
Lip-licking is a natural response to any irritation on the lips. Many people don’t realize how often they lick their lips throughout the day. It can become a vicious cycle often due to:
Harsh weather conditions Sunburn Anxiety Chronic dry skin Atopic dermatitis (the most common type of eczema) Nasal congestion that leads to mouth breathing Certain health conditions (like lupus or Crohn’s disease) Medications (like vitamin A or diuretics)
Chronic lip-licking can break the lips’ protective barrier, creating a situation in which other inflammatory skin conditions (cheilitis simplex or angular cheilitis) can form.
Diagnosis
Lip licker’s dermatitis can resemble other skin conditions around the mouth, so it’s important to get a proper diagnosis.
A healthcare provider will want to rule out conditions like perioral dermatitis, allergic contact dermatitis, precancerous spots, or another underlying health condition.
They’ll examine the area, review your health history, and ask questions about your symptoms. From there, it’s possible to receive a referral to a dermatologist (a doctor specializing in skin, hair, and nails) for further consultation or through patch testing or swabbing to check for allergies or infections.
Treatment
Treating lip licker’s dermatitis involves alleviating the current symptoms and addressing the habits that lead the condition to form in the first place.
Healthcare providers will likely recommend strategies such as:
Applying a lip balm (containing ceramides, petrolatum, or shea butter) multiple times a day Drinking plenty of water to stay hydrated Protecting the lip area from harsh weather conditions Using a prescription topical steroid ointment to help inflammation, if needed Trying an over-the-counter (OTC) antihistamine if your lips feel severely itchy
To break the habit of licking your lips throughout the day, experts suggest applying lip balm or chewing gum instead. Certain habit reversal techniques may be recommended, such as muscle relaxation, deep breathing exercises, or cognitive behavioral therapy.
Summary
Lip licker’s dermatitis is dryness, redness, scaling, and itchiness on or around the lips triggered by repeated irritation from saliva contact. It’s commonly experienced during dry or winter weather when there’s a natural urge to lick dry or cracked lips. Most of the time, lip licker’s dermatitis can be treated through simple lifestyle changes after a proper diagnosis.
A Word From Verywell
After a diagnosis with a healthcare provider, lip licker’s dermatitis can often be managed by keeping lips and surrounding skin moisturized and limiting the habit of lip licking. Speak with your healthcare provider if at-home treatments are not working. More severe cases may require prescription-strength ointment or behavioral therapy.
