Perioral Dermatitis: Symptoms, Causes, Treatment

What are the symptoms of perioral dermatitis?

Perioral dermatitis is a common skin condition characterized by a rash around the mouth, though it can also affect other parts of the face. It primarily affects women between the ages of 20 and 45 but can also occur in men and children. The exact cause is not well understood, but it is often associated with the use of topical steroids, cosmetics, or certain skincare products. Below are the detailed symptoms of perioral dermatitis:

1. Redness Around the Mouth (Erythema)

• Description: Redness is one of the most prominent features of perioral dermatitis. The rash typically appears around the mouth and may extend to the nose, chin, and sometimes the eyes (referred to as periorificial dermatitis).
• Location: The rash generally spares the area directly around the lips, leaving a narrow band of unaffected skin, but it surrounds the outer edge of the mouth.
• Appearance: The redness is often patchy, with scattered spots of inflammation.

2. Papules and Pustules

• Description: Small, raised, red bumps (papules) or pus-filled bumps (pustules) are commonly seen in perioral dermatitis. These lesions resemble acne but are not related to clogged pores.
• Size and Shape: The bumps are typically small (1–2 mm in diameter) and may appear in clusters. They are not deep lesions but rather surface-level bumps.
• Location: They typically appear around the mouth but may also extend to the cheeks, chin, nasolabial folds (the lines from the nose to the corners of the mouth), and the area under the eyes.

3. Burning or Stinging Sensation

• Description: Patients with perioral dermatitis often experience a burning or stinging sensation in the affected area, particularly as the rash becomes more inflamed. It is usually described as mild to moderate discomfort.
• Associated with: The burning or stinging feeling is often triggered by the application of topical products or during activities like washing the face or exposure to sunlight.

4. Dry, Flaky Skin

• Description: The skin in the affected area may become dry, flaky, or scaly. This can contribute to a sensation of tightness or discomfort. The dry patches often appear alongside the red bumps and papules.
• Location: The dry, flaky skin is most commonly found around the mouth and on the chin, though it can extend to other parts of the face.
• Appearance: The flaking may be subtle or more pronounced, giving the skin a rough texture.

5. Itching

• Description: Although less common than the burning sensation, some patients may experience mild itching. This itching can exacerbate the condition if the area is scratched or irritated.
• Location: The itching is typically localized to the affected areas around the mouth, chin, or nose.
• Severity: Itching is generally mild but may become more noticeable as the condition worsens.

6. Scaling

• Description: The affected skin may develop fine scaling, which gives it a rough texture. This scaling often appears after the rash has been present for some time and is part of the skin’s inflammatory response.
• Location: Scaling is typically found on the skin surrounding the mouth but can extend to the chin, cheeks, and nose.
• Associated With: The scaling may be exacerbated by washing the face or using certain cosmetic products, which can irritate the skin further.

7. Clear Fluid Oozing

• Description: In some cases, the papules and pustules associated with perioral dermatitis may ooze a clear fluid. This is a sign of inflammation and irritation.
• Location: The oozing is typically localized to the individual bumps or pustules and is often followed by the formation of small crusts or scabs.

8. Crusting

• Description: As the papules and pustules heal, they may develop thin, crust-like coverings, especially if they have oozed fluid. This crusting is part of the body’s healing process but can make the skin feel rough and dry.
• Location: Crusting is usually seen on the inflamed areas around the mouth and on the chin.
• Severity: The crusts are typically small and not painful, but they can contribute to the unsightly appearance of the rash.

9. Sensation of Tightness

• Description: Many patients report a feeling of tightness in the skin around the mouth, especially in areas where the rash is present. This tightness is often due to inflammation and dryness in the skin.
• Location: The tightness is primarily felt in the affected areas around the mouth, nose, and chin.
• Associated With: The tight feeling may worsen with facial movements, such as talking or smiling, due to the skin’s reduced elasticity.

10. Spread of the Rash

• Description: While the rash initially begins around the mouth, it can spread to other parts of the face over time. The rash may move up toward the eyes (causing periorbital dermatitis) or down toward the chin and jawline.
• Extent: In more severe cases, the rash can spread to the entire lower half of the face, though it still tends to avoid the area directly around the lips.

11. Lack of Involvement of the Lips

• Description: One distinctive feature of perioral dermatitis is that it generally spares the lips themselves. There is usually a clear demarcation between the rash and the lips, with a small ring of unaffected skin around the vermilion border (the edge where the lips meet the skin of the face).
• Significance: This feature helps distinguish perioral dermatitis from other conditions like contact dermatitis or eczema, which may affect the lips more directly.

12. Absence of Systemic Symptoms

• Description: Unlike some other dermatological conditions associated with infections or systemic inflammation, perioral dermatitis typically does not cause fever, fatigue, or other systemic symptoms. It is primarily a localized skin issue.
• Differentiation: This lack of systemic symptoms helps distinguish perioral dermatitis from more serious skin infections or inflammatory conditions that may require different treatments.

Psychosocial Impact

• Description: Though not a physical symptom, perioral dermatitis can cause significant psychological distress, especially due to its appearance on a visible part of the body (the face). Patients may experience embarrassment or self-consciousness, particularly if the rash is persistent or severe.
• Emotional Effects: Anxiety, frustration, and social withdrawal are common among those dealing with chronic or severe cases of perioral dermatitis.

Conclusion

Perioral dermatitis presents primarily as a red, bumpy rash around the mouth, with symptoms including papules, pustules, redness, and a burning sensation. It may also cause dryness, scaling, and a feeling of tightness in the affected area. While the condition is generally localized to the face and does not cause systemic symptoms, it can spread to other parts of the face, leading to discomfort and cosmetic concerns. Prompt treatment and avoiding triggers like topical steroids and irritating cosmetics are key to managing perioral dermatitis.

What are the causes of perioral dermatitis?

The exact cause of perioral dermatitis is not fully understood, but several factors are known to contribute to its development. Below are the detailed potential causes and contributing factors:

1. Topical Steroid Use

• Description: One of the most common causes of perioral dermatitis is the prolonged use of topical corticosteroids on the face. These steroids are often prescribed to treat various skin conditions, such as eczema or psoriasis.
• Mechanism: Topical steroids reduce inflammation, but their overuse can cause thinning of the skin and disrupt the skin’s natural barrier. This leads to rebound inflammation once steroid use is stopped, resulting in the characteristic rash of perioral dermatitis.
• Examples: Both prescription-strength corticosteroids (e.g., hydrocortisone) and over-the-counter creams may trigger this condition.

2. Topical Medications

• Description: Other non-steroid topical medications, such as those used for acne, rosacea, or other skin disorders, may contribute to perioral dermatitis.
• Mechanism: These products can irritate sensitive facial skin, leading to inflammation and the development of a rash.
• Examples: Medications like retinoids or benzoyl peroxide, used for acne treatment, can exacerbate perioral dermatitis.

3. Cosmetic Products

• Description: The use of facial creams, lotions, moisturizers, and other cosmetics is another known factor. Heavily moisturizing products or those containing certain irritating ingredients can block pores and trigger inflammation.
• Mechanism: Cosmetics can disrupt the natural oil balance on the skin and alter the skin’s barrier function, leading to irritation and the formation of papules and pustules characteristic of perioral dermatitis.
• Ingredients: Fragrances, preservatives, and paraffin-based ingredients in creams or makeup can contribute to flare-ups.
• Example: Heavy moisturizers or foundation makeup, especially those containing petrolatum, are often implicated.

4. Hormonal Changes

• Description: Fluctuations in hormone levels, particularly in women, may contribute to the onset of perioral dermatitis.
• Mechanism: Changes in estrogen and progesterone levels during menstruation, pregnancy, or menopause can influence skin sensitivity and oil production, leading to flare-ups.
• Example: Many women experience outbreaks during the luteal phase of their menstrual cycle (just before menstruation) or during pregnancy, when hormonal fluctuations are significant.

5. Oral Contraceptives

• Description: Some women who use oral contraceptives (birth control pills) report the onset or worsening of perioral dermatitis.
• Mechanism: Oral contraceptives can alter hormone levels, especially those related to estrogen and progesterone, which may exacerbate skin inflammation and make the skin more prone to irritation.

6. Fluoridated Toothpaste

• Description: Fluoridated toothpaste and other dental hygiene products may be a trigger for some individuals with perioral dermatitis.
• Mechanism: Fluoride in toothpaste can irritate the skin around the mouth, particularly in individuals with sensitive skin, causing inflammation and the development of a perioral rash.
• Example: Switching to a non-fluoridated toothpaste has been reported to improve symptoms in some cases.

7. Microbial Overgrowth (Bacteria and Fungi)

• Description: While perioral dermatitis is not primarily caused by an infection, the overgrowth of normal skin flora such as bacteria or fungi may play a role.
• Mechanism: Skin that has been weakened by steroid use, overuse of cosmetics, or other factors can become a breeding ground for bacterial or fungal overgrowth, leading to inflammation.
• Examples: Bacteria like Staphylococcus aureus or fungal organisms like Candida may exacerbate the condition in some individuals.

8. Environmental Factors

• Description: Certain environmental factors, such as heat, humidity, and UV exposure, can trigger or worsen perioral dermatitis.
• Mechanism: Hot, humid conditions may cause increased sweating and oil production, which can irritate the skin around the mouth. UV exposure can also weaken the skin’s protective barrier, making it more susceptible to inflammation.
• Examples: People living in hot, humid climates may experience more frequent flare-ups, while those exposed to strong sunlight without proper protection can also be at higher risk.

9. Stress

• Description: Stress is known to exacerbate many skin conditions, including perioral dermatitis.
• Mechanism: Stress can lead to the release of certain hormones (such as cortisol), which can affect the skin’s immune function, making it more prone to inflammation and irritation. It can also lead to poor skincare practices or the overuse of products, which may worsen the condition.
• Example: Emotional or psychological stress, such as during major life changes, may trigger flare-ups of perioral dermatitis.

10. Occlusive Face Masks or Barrier Products

• Description: Wearing face masks or using occlusive skincare products (those that create a barrier on the skin) can contribute to the development of perioral dermatitis.
• Mechanism: Occlusive products trap heat and moisture, creating an environment that can irritate the skin and promote bacterial growth, leading to inflammation.
• Examples: Face masks worn for extended periods (such as during the COVID-19 pandemic) or heavy barrier creams used for skincare can trigger or worsen the condition.

11. Weather Conditions

• Description: Cold, dry weather can also lead to the onset or exacerbation of perioral dermatitis.
• Mechanism: Cold weather can strip the skin of its natural oils, leading to dryness and irritation, which may contribute to inflammation and the development of the rash.
• Examples: Dry, winter months are often associated with flare-ups due to increased skin dryness and sensitivity.

12. Immune System Dysfunction

• Description: Though not common, underlying immune system issues could contribute to perioral dermatitis in some cases.
• Mechanism: An impaired immune response could result in an abnormal reaction to normal skin flora, cosmetic products, or environmental factors, leading to inflammation and rash.
• Examples: Conditions that suppress the immune system, such as chronic illnesses or immunosuppressive medications, could potentially contribute to the development of perioral dermatitis.

13. Overuse of Skincare Products

• Description: The excessive use of facial cleansers, scrubs, or exfoliants can irritate the skin and trigger perioral dermatitis.
• Mechanism: Frequent washing and use of harsh chemicals can disrupt the skin’s protective barrier, leading to increased susceptibility to irritation and inflammation.
• Examples: Using strong facial cleansers, toners with alcohol, or exfoliating too often can irritate the delicate skin around the mouth.

14. Allergic Reactions

• Description: Allergic contact dermatitis to certain products or allergens can trigger perioral dermatitis in some individuals.
• Mechanism: Contact with allergens, such as certain skincare ingredients, fragrances, or preservatives, can cause an allergic reaction, leading to inflammation and rash formation around the mouth.
• Examples: Allergies to cosmetics, sunscreen, or even food products can cause flare-ups.

Conclusion

The causes of perioral dermatitis are multifactorial, with common triggers including the use of topical steroids, certain cosmetic products, hormonal fluctuations, microbial overgrowth, and environmental factors. Reducing exposure to known triggers and avoiding harsh skin treatments are key steps in managing and preventing the condition.

How is the diagnosis of perioral dermatitis made?

The diagnosis of perioral dermatitis is primarily clinical, based on the appearance of the skin and patient history. A healthcare provider, usually a dermatologist, will conduct a thorough evaluation to distinguish perioral dermatitis from other skin conditions. The diagnostic process typically includes the following steps:

1. Patient History:

• Symptom Review: The healthcare provider will ask about the duration, location, and nature of the rash, as well as any associated symptoms like itching, burning, or dryness.
• Medical History: They will inquire about the patient’s medical history, including any history of skin conditions, use of topical or oral steroids, other medications, and hormonal changes.
• Lifestyle and Environmental Factors: The provider may ask about skincare routines, cosmetic use, toothpaste, dietary habits, and exposure to environmental factors.

2. Clinical Examination:

• Visual Inspection: The healthcare provider will visually inspect the affected areas, typically around the mouth, nose, and eyes. They will look for characteristic features such as small, red or pink papules, pustules, and scaling.
• Distribution and Pattern: They will note the distribution of the rash and whether it spares the vermilion border of the lips, a common characteristic of perioral dermatitis.

3. Differential Diagnosis:

• Exclusion of Other Conditions: The provider will differentiate perioral dermatitis from other similar conditions, such as acne, rosacea, seborrheic dermatitis, and allergic contact dermatitis. This is done through a combination of clinical examination and patient history.

4. Diagnostic Tests (if needed):

• Skin Swab or Biopsy: In rare cases where the diagnosis is unclear, a skin swab for bacterial culture or a skin biopsy may be performed to rule out other conditions. However, these are not commonly required for diagnosing perioral dermatitis.

5. Assessment of Contributing Factors:

• Evaluation of Topical and Oral Products: The healthcare provider will review any topical products, such as creams, lotions, and cosmetics, as well as oral medications, particularly corticosteroids, that the patient may be using.

6. Treatment Response (in some cases):

• Trial of Treatment: Sometimes, a diagnosis is confirmed by observing the response to treatment, such as discontinuing topical steroids or other potential irritants and initiating appropriate therapy.

Early diagnosis and appropriate treatment are important for managing perioral dermatitis and preventing it from becoming chronic or worsening. If you suspect you have perioral dermatitis or have noticed a persistent rash around your mouth, nose, or eyes, it’s advisable to consult a dermatologist for a professional evaluation and guidance on treatment.

What is the treatment for perioral dermatitis?

The treatment of perioral dermatitis aims to reduce inflammation, eliminate potential triggers, and prevent recurrence. The treatment plan typically involves both topical and oral medications, along with lifestyle and skincare adjustments. The specific approach may vary depending on the severity of the condition and the individual patient. Here’s an overview of common treatments:

1. Discontinuation of Triggering Agents:

• Topical Steroids: The first step is usually to discontinue the use of topical steroids, which are a common cause of perioral dermatitis. This should be done under medical supervision to avoid a flare-up known as “steroid withdrawal.”
• Irritating Skincare Products: Avoiding irritating cosmetics, heavy moisturizers, and other skincare products that may aggravate the condition.

2. Topical Treatments:

• Topical Antibiotics: Commonly prescribed options include metronidazole, clindamycin, and erythromycin, which help reduce inflammation and bacterial growth.
• Topical Anti-inflammatory Agents: Pimecrolimus or tacrolimus creams may be used to reduce inflammation, particularly when long-term treatment is needed or when avoiding steroids.
• Azelaic Acid: This topical agent can help reduce inflammation and has antibacterial properties.

3. Oral Treatments:

• Oral Antibiotics: For more severe cases or when topical treatments are ineffective, oral antibiotics such as tetracyclines (doxycycline, minocycline) or macrolides (erythromycin) may be prescribed. These antibiotics help reduce inflammation and control the bacterial component of the condition.
• Oral Antifungals: In rare cases where a fungal component is suspected, antifungal medications may be prescribed.

4. Skincare and Lifestyle Adjustments:

• Gentle Skincare Routine: Use mild, fragrance-free cleansers and avoid harsh scrubs or exfoliants. Non-comedogenic and hypoallergenic products are recommended.
• Avoiding Triggers: Identifying and avoiding potential triggers, such as certain foods, toothpaste containing fluoride, and stress, can help manage symptoms.
• Sun Protection: Wearing sunscreen and avoiding excessive sun exposure is important, as sunlight can sometimes exacerbate the condition.

5. Gradual Tapering of Steroids:

• If Currently Using Steroids: For patients who have been using topical steroids, a gradual tapering under medical supervision may be necessary to avoid a rebound flare-up.

6. Monitoring and Follow-Up:

• Regular Check-ups: Follow-up visits with a dermatologist are important to monitor the condition, assess the effectiveness of the treatment, and make adjustments as needed.

7. Patient Education:

• Education on Proper Skincare: Educating patients about gentle skincare practices and the importance of avoiding potential triggers can help prevent recurrence.

8. Additional Considerations:

• For Severe or Refractory Cases: In cases that do not respond to standard treatments, referral to a dermatologist for further evaluation and specialized care may be necessary.

It’s essential to consult with a healthcare provider or dermatologist for a proper diagnosis and personalized treatment plan, as the condition can be mistaken for other skin disorders. Self-treatment, especially with topical steroids, can worsen the condition, so professional guidance is crucial.
