Rosacea: Symptoms, Causes & Treatment

Rosacea is a chronic inflammatory skin condition that primarily affects the face, characterized by persistent redness, visible small blood vessels, and acne-like bumps. Patients often experience burning or itching sensations in affected areas. The condition varies in severity and symptoms from person to person.

The exact cause of rosacea is not fully understood, but it is believed to result from a combination of genetic, environmental, and immune factors that cause recurring inflammation of blood vessels. The disease is not contagious and does not cause permanent scarring, although it can have significant psychological impact due to its visible nature. Rosacea is more common in individuals with fair skin and Northern European ancestry; in the Middle East and Jordan, cases are recognized but may be underdiagnosed compared to Western countries.

Although there is no cure, available treatments effectively manage symptoms with consistent use. Regular follow-up with a dermatologist and identification of personal triggers are essential for optimal disease control.

Symptoms of rosacea vary widely between individuals and range from mild to severe. Patients often experience periods of improvement followed by flare-ups. Some symptoms may be more pronounced in women (particularly cheek redness), while men may experience nasal skin thickening.

• Persistent facial redness: Constant redness on cheeks, nose, forehead, and chin that may intensify over time.
• Episodic flushing: Sudden waves of facial redness and warmth sensation without an obvious trigger.
• Visible blood vessels: Small red lines appearing on the skin due to dilated capillaries.
• Bumps and pustules: Red nodules or pus-filled lesions resembling acne but unresponsive to standard acne treatments.
• Eye redness and swelling: Irritation, redness, tearing, or sandy sensation in the eyes (Ocular rosacea).
• Nasal skin thickening: Over time, nose skin may thicken and enlarge (Rhinophyma), particularly in men.
• Burning and itching: Sensation of heat or itching in affected areas.
• Dry and tight skin: Affected areas may become dry and feel tight.
• Skin fragility: Skin becomes thin and sensitive to touch and external irritants.

• Blood vessel instability: Hereditary predisposition to easy dilation and constriction of blood vessels causes recurrent facial flushing.
• Overactive immune response: An abnormal immune reaction to certain triggers leads to persistent inflammation.
• Microbial involvement: Bacteria such as Bacillus oleronius and Demodex mites may trigger inflammatory pathways.
• Skin barrier defect: Impaired outer skin layer allows increased water loss and easier irritation.
• Vascular dysregulation: Impaired blood vessel control and elevated nitric oxide production increase redness.
• Environmental factors: Chronic exposure to extreme heat, cold, or UV radiation exacerbates symptoms.

• Age: Typically appears between ages 30-50, but can occur at any age.
• Gender: More common in women, but men often experience more severe symptoms.
• Skin tone: More prevalent in fair-skinned individuals of Scandinavian, Celtic, or Irish descent.
• Family history: Having a parent or close relative with rosacea increases risk.
• Sensitive skin: People with naturally sensitive skin are more susceptible.
• Gastrointestinal disorders: GERD and inflammatory bowel diseases may increase risk.
• Prolonged topical steroid use: Excessive use of strong steroid creams may worsen symptoms.
• Psychological stress: Emotional stress and anxiety trigger flushing episodes.

Diagnosis is primarily based on clinical examination of the skin and characteristic symptoms. There are no specific blood tests or laboratory markers for rosacea, though the doctor may order tests to rule out similar conditions. Early and accurate diagnosis is important for starting appropriate treatment.

• Clinical examination: The doctor carefully examines the skin to assess the pattern of redness, visible blood vessels, and bumps. They will also inquire about triggers and symptom history.
• Diagnostic criteria: Persistent facial redness in the central face plus at least one of the following (visible blood vessels, papules/pustules, or skin thickening) confirms diagnosis.
• Exclusion of similar conditions: Tests may be ordered to rule out lupus, rosacea mimics, or other dermatological conditions (allergies, seborrheic dermatitis).
• Eye examination: If the patient reports eye symptoms, referral to an ophthalmologist is recommended to assess Ocular rosacea.
• Documentation photos: The doctor may take photographs to document baseline severity and monitor changes over time.

Medications

• Topical creams and gels: Metronidazole (0.75%-1%), Ivermectin (1%), Sulfacetamide-Sulfur, and Azelaic acid (15%-20%) applied twice daily. Reduce inflammation and redness within 2-4 weeks.
• Brimonidine: Constricts blood vessels and reduces redness within minutes to hours. Suitable for daily use before social events.
• Low-dose doxycycline: 40-50 mg daily (below antibacterial dose) for anti-inflammatory properties. Used for at least 3 months.
• Other antibiotics: In severe cases, oral Tetracycline, Minocycline, or Sulfamethoxazole-Trimethoprim may be used.
• Antihistamines: Oral allergy medications may help reduce flushing episodes.

Procedures and Cosmetic Treatments

• Laser and Intense Pulsed Light (IPL): Used to reduce visible blood vessels and redness. Requires multiple sessions (3-5 sessions) and periodic maintenance. High efficacy but may be costly.
• Excimer laser: May be used in cases resistant to topical treatment.
• Surgical procedures (for advanced cases): In severe Rhinophyma (nasal thickening), surgery may be performed to remove excess tissue.

Lifestyle Changes and Skincare

• Identify and avoid personal triggers: Determine and avoid exacerbating factors (extreme heat, alcohol, spicy foods, coffee, stress, heavy face powders).
• Sun protection: Use SPF 30+ sunscreen daily, stay in shade, and wear wide-brimmed hats.
• Gentle skincare routine: Wash face with lukewarm water and mild soap, avoid harsh scrubbing and products containing alcohol or strong fragrances.
• Avoid irritating cosmetics: Use light, fragrance-free cosmetics, avoid heavy powders and strong moisturizers.
• Stress management: Practice yoga, meditation, or relaxation techniques to reduce flushing episodes.
• Avoid strenuous exercise in heat: Exercise during cooler times and maintain adequate hydration.

• Ocular Rosacea: Eye and eyelid inflammation causing persistent redness, dryness, or sandy sensation. May lead to vision problems if untreated.
• Rhinophyma (nasal thickening): Enlargement and thickening of nose skin becoming noticeably red and bulbous, more common in men. May require surgical intervention.
• Psychological and social impact: Persistent redness may cause anxiety, depression, or social avoidance, especially in severe cases.
• Symptom progression over time: Without proper treatment, symptoms may gradually worsen and become more difficult to control.
• Secondary dermatitis: Constant itching and scratching may cause secondary infection or additional irritation.
• Treatment resistance: Some cases may be resistant to available treatments and may require multiple therapeutic trials.

• Avoid known triggers: Identify and avoid foods, beverages, and activities that cause flushing (alcohol, coffee, spicy foods, extreme heat).
• Sun protection: Use high-protection sunscreen (SPF 30+) daily, even on cloudy days, and wear protective clothing and wide-brimmed hats.
• Gentle skincare: Avoid harsh cleansers and scrubs, wash with lukewarm water instead of hot water, and use fragrance-free light moisturizers.
• Stress management: Practice relaxation techniques, meditation, yoga, and minimize psychological stress whenever possible.
• Avoid irritating cosmetics: Choose light, fragrance-free cosmetics and avoid products with strong alcohol content.
• Maintain healthy lifestyle: Ensure adequate sleep, moderate exercise, and a balanced healthy diet.
• Avoid overusing topical steroids: Use strong creams only as prescribed by a doctor and avoid unnecessary use.
• Treat gastrointestinal issues: Managing GERD and treating inflammatory bowel conditions may help reduce symptoms.
