Overview

Acne rosacea, commonly known simply as rosacea, is a chronic inflammatory skin condition that primarily affects the face. It causes redness, visible blood vessels, and acne-like bumps, often concentrated on the cheeks, nose, chin, and forehead. Unlike typical acne, rosacea can also cause flushing and skin sensitivity. The condition is more prevalent in adults aged 30 to 60, especially those with fair skin. While rosacea is not contagious or life-threatening, it can significantly impact self-esteem and quality of life if left untreated. Early recognition and management can help control symptoms and prevent flare-ups.

Causes

The exact cause of acne rosacea is unknown, but several contributing factors are believed to play a role:

• Genetic predisposition: Rosacea tends to run in families, suggesting a hereditary link.
• Abnormal immune response: Some people with rosacea have an overactive immune system that triggers inflammation.
• Demodex mites: Higher numbers of these skin mites have been found on the skin of rosacea patients, possibly contributing to irritation.
• Environmental triggers: Sun exposure, extreme temperatures, wind, and hot beverages are known to trigger flare-ups.
• Bacteria: Helicobacter pylori, a bacteria linked to stomach ulcers, has been associated with rosacea in some studies.
• Vascular dysfunction: Abnormalities in facial blood vessels may lead to persistent redness and visible capillaries.
• Hormonal factors and stress: Emotional stress and hormonal changes can worsen symptoms.

Symptoms

Rosacea manifests through a range of skin-related symptoms, which may vary in severity:

• Facial redness: Persistent redness (erythema) primarily affecting the central face.
• Flushing: Frequent blushing or flushing episodes, sometimes accompanied by a burning sensation.
• Visible blood vessels: Small, dilated blood vessels (telangiectasia) may become visible, especially on the cheeks and nose.
• Bumps and pimples: Acne-like papules and pustules that resemble breakouts without blackheads.
• Skin thickening: In advanced cases, the skin may thicken, particularly around the nose (rhinophyma).
• Eye irritation: Ocular rosacea causes red, dry, irritated eyes and swollen eyelids.
• Skin sensitivity: Affected skin may feel tender, hot, or easily irritated by skincare products.

Diagnosis

Diagnosis of acne rosacea is typically based on a clinical examination and history:

• Physical examination: A dermatologist will assess facial redness, skin texture, and presence of pimples or visible blood vessels.
• Medical history: Evaluation of symptoms, triggers, and family history helps confirm rosacea.
• No definitive tests: There are no specific laboratory tests for rosacea; diagnosis is based on symptoms.
• Rule out other conditions: Other skin conditions like acne vulgaris, lupus, or seborrheic dermatitis are excluded.
• Ocular assessment: In cases of eye involvement, an eye examination may be recommended.

Treatment

While rosacea cannot be cured, treatments help manage symptoms and prevent flare-ups:

• Topical treatments: Metronidazole, azelaic acid, and ivermectin creams or gels reduce redness and inflammation.
• Oral medications: Low-dose doxycycline or other oral antibiotics are used for moderate to severe inflammatory rosacea.
• Laser therapy: Laser and light treatments (such as IPL) can reduce visible blood vessels and persistent redness.
• Skincare routines: Gentle cleansers, moisturizers, and sunscreen are essential to protect sensitive skin.
• Avoiding triggers: Identifying and avoiding known triggers such as sun, alcohol, spicy foods, and hot drinks helps prevent flare-ups.
• Eye care: For ocular rosacea, eyelid hygiene and prescribed eye drops may be necessary.

Prognosis

The prognosis for acne rosacea is generally good with consistent treatment and management:

• Symptom control: Most individuals experience significant improvement in symptoms with appropriate therapy.
• Chronic nature: Rosacea is a long-term condition with periods of flare-ups and remission, requiring ongoing care.
• Preventing progression: Early treatment can prevent worsening symptoms, especially skin thickening or eye complications.
• Minimal impact with proper care: With lifestyle adjustments and medical management, most people lead normal lives without severe cosmetic issues.

Managing rosacea involves a combination of medical treatment, good skincare practices, and lifestyle changes, all of which can lead to clearer, healthier skin.
