Perioral Dermatitis

What Is Perioral Dermatitis?

Perioral dermatitis is a chronic inflammatory skin condition that typically presents as small red bumps, scaling, and irritation around the mouth, nose, or eyes. It is often mistaken for acne, rosacea, or eczema, but has distinct underlying drivers and treatment considerations.

The condition frequently develops after disruption of the skin barrier or prolonged use of topical corticosteroids or irritating skincare products. The skin becomes increasingly reactive, leading to cycles of inflammation, sensitivity, and persistent rash.

Perioral dermatitis often follows a pattern of temporary improvement followed by recurrence, particularly when underlying triggers are not addressed.

Why Perioral Dermatitis Develops

Perioral dermatitis is driven by a combination of barrier disruption, inflammation, and microbial imbalance.

Skin barrier disruption

Overuse of topical products or medications weakens the skin’s protective barrier.

Topical steroid exposure

Corticosteroids can temporarily suppress inflammation but lead to rebound worsening over time.

Microbiome imbalance

Changes in the skin’s microbial environment contribute to ongoing inflammation.

Inflammatory reactivity

The skin becomes increasingly sensitive to products, environment, and internal triggers.

These factors contribute to the persistent and often treatment-resistant nature of perioral dermatitis.

Common triggers

Common Triggers for Perioral Dermatitis

Perioral dermatitis is often worsened by ongoing exposure to triggers that disrupt the skin barrier or increase inflammation.

Common triggers include:

• topical corticosteroids
• heavy or occlusive skincare products
• fluorinated toothpaste
• cosmetics and makeup
• harsh cleansers or over-exfoliation
• hormonal fluctuations
• stress
• environmental irritation

Identifying and removing triggers is often a key part of improving symptoms.

Our Approach to Perioral Dermatitis

Dr. Larivee provides physician-led care for patients with persistent or treatment-resistant perioral dermatitis. Rather than repeatedly cycling through topical treatments, care focuses on restoring skin barrier function and reducing inflammatory triggers.

Treatment plans are individualized based on severity, duration, prior treatments, and overall skin sensitivity.

Approaches may include:

1.Clinical evaluation

Review of product use, medication history, and symptom patterns.

2.Trigger identification and removal

Reducing exposure to factors that perpetuate inflammation.

3. Skin barrier restoration

Simplifying skincare and supporting barrier repair.

4.Microbiome support

Addressing microbial factors contributing to inflammation.

5.Gradual skin stabilization

Focusing on long-term improvement and reducing recurrence.

Who This Care Is Designed For

This care model may be appropriate for patients who:

• have a persistent rash around the mouth, nose, or eyes
• have been treated with steroids and experienced rebound worsening
• have not improved with standard topical treatments
• have highly sensitive or reactive skin
• want a physician-guided integrative dermatology approach

This practice focuses on chronic inflammatory skin conditions and may not be appropriate for urgent dermatologic care.

Schedule an introductory consultation to discuss your skin concerns and determine whether our integrative dermatology approach is appropriate for your care.
