Understanding Acne Rosacea: Symptoms, Causes & Treatment Options

Acne rosacea (commonly just rosacea) is a chronic inflammatory skin condition primarily affecting the central face. It is distinct from acne vulgaris.

Common Signs & Symptoms

• Persistent facial redness (erythema) on cheeks, nose, chin, forehead.
• Papules and pustules (red bumps, pus-filled pimples) without comedones (blackheads/whiteheads).
• Visible blood vessels (telangiectasia).
• Skin thickening (phymatous changes), especially rhinophyma (bulbous nose).
• Ocular involvement: Dryness, irritation, blepharitis, conjunctivitis; rarely vision loss.

Triggers & Pathophysiology

Exact cause is unknown; involves genetic predisposition, immune dysregulation, Demodex mites, vascular reactivity, and environmental triggers:

• Sun exposure
• Heat, spicy foods, alcohol
• Stress, hot beverages
• Harsh skincare products

Management (No Cure, But Control)

• Topical: Metronidazole, azelaic acid, ivermectin, brimonidine (for erythema).
• Oral: Low-dose doxycycline (anti-inflammatory), isotretinoin (severe/resistant cases).
• Laser/light therapy: Vascular lasers (PDL, Nd:YAG) reduce telangiectasia and background erythema.
• Surgery: For rhinophyma (CO₂ laser, electrosurgery, scalpel excision).
• Skincare: Gentle cleanser, moisturizer, broad-spectrum SPF 30+ daily.
• Trigger diary: Identify and avoid personal flare factors.

When to See a Dermatologist

Early diagnosis prevents progression. Ocular symptoms require prompt ophthalmology referral.
