Comprehensive Guide to Rosacea Management: From Diagnosis to Treatment
Rosacea is a common chronic skin condition that affects millions of people worldwide, including many residents of Cape Town. This comprehensive guide will explore the latest approaches to diagnosing and managing rosacea, drawing on insights from dermatologists and recent research.
Understanding Rosacea
Rosacea is a chronic inflammatory skin condition primarily affecting the central face. It's characterized by:
Persistent redness (erythema)
Flushing
Visible blood vessels (telangiectasia)
Papules and pustules
In some cases, skin thickening (phymatous changes)
While rosacea can affect anyone, it's most common in fair-skinned individuals between 30-50 years old. In Cape Town, dermatologists often see patients with various skin types affected by this condition.
Diagnosis and Classification
Dermatologists diagnose rosacea based on clinical presentation. The National Rosacea Society Expert Committee has defined four subtypes:
Erythematotelangiectatic Rosacea (redness + blood vessels)
Papulopustular Rosacea (acne like)
Phymatous Rosacea (enlargement of nose and other areas on the face)
Ocular Rosacea (eye Rosacea)
Many patients may present with features of multiple subtypes, requiring a comprehensive approach to management.
Management Strategies
1. Topical Treatments
Topical therapies are the cornerstone of rosacea management for many patients. Common options include:
Metronidazole: Available as 0.75% and 1% formulations, metronidazole is effective in reducing inflammation and redness. Learn more about our topical treatments
Azelaic Acid: A 15% gel formulation has shown efficacy in reducing papules, pustules, and erythema.
Ivermectin: A relatively new addition, 1% ivermectin cream has shown promising results in managing papulopustular rosacea.
Brimonidine and Oxymetazoline: These alpha-adrenergic agonists are specifically approved for persistent facial erythema.
2. Oral Medications
For more severe cases or those not responding to topical treatments, oral medications may be prescribed:
Tetracyclines: Doxycycline, particularly at a sub-antimicrobial dose (40mg daily), is commonly used for its anti-inflammatory properties.
Isotretinoin: In severe, recalcitrant cases, low-dose isotretinoin may be considered.
3. Light and Laser Therapies
Many dermatologists in Cape Town are now offering light-based treatments for rosacea:
Intense Pulsed Light (IPL): Effective for reducing redness and visible blood vessels.
Pulsed Dye Laser (PDL): Particularly useful for treating persistent telangiectasias.

4. Skincare and Sun Protection
Proper skincare is crucial in managing rosacea:
Use gentle, non-irritating cleansers
Apply broad-spectrum sunscreen daily
Moisturize to maintain skin barrier function
5. Trigger Avoidance
Identifying and avoiding personal triggers is key to managing rosacea flare-ups. Common triggers include:
Sun exposure
Hot or spicy foods
Alcohol
Extreme temperatures
Stress
Emerging Treatments
Recent research has highlighted potential new treatments for rosacea:
Topical Minocycline: A new foam formulation shows promise in reducing inflammatory lesions.
Microbiome-based Therapies: Targeting the skin microbiome may offer new avenues for treatment.
Botulinum Toxin: Some studies suggest botulinum toxin injections may help with persistent facial flushing.
When to See a Dermatologist
If you're experiencing persistent facial redness, flushing, or acne-like breakouts, it's important to consult a dermatologist. Early diagnosis and treatment can help manage symptoms and prevent progression of the condition.
