What are rosacea and couperose?
Rosacea is a chronic inflammatory skin condition that primarily affects the central part of the face, manifesting as redness, dilated blood vessels (telangiectasias), papules, and pustules. It is often mistaken for acne or an allergic reaction. Couperose, in turn, is either a manifestation of rosacea or an independent condition characterized by the appearance of a persistent vascular network on the face caused by the dilation of small capillaries. Both problems significantly affect patients' quality of life, causing discomfort and psychological distress.
Causes and Risk Factors for Rosacea Development
The exact causes of rosacea are not yet fully understood, but it is believed to be based on a combination of genetic predisposition and environmental factors. Key mechanisms include innate immune system disorders, neurovascular dysregulation, ultraviolet radiation exposure, and the role of microorganisms such as the mite Demodex folliculorum and the bacterium Helicobacter pylori. Factors that provoke flare-ups include:
- Consumption of hot drinks and spicy foods.
- Alcohol.
- Sun and wind exposure.
- Stress and emotional distress.
- Sudden temperature changes.
- Certain medications (e.g., vasodilators).
- Use of aggressive cosmetics [1].
Understanding these factors helps in developing individual management strategies for the disease and reducing the frequency of flare-ups [2].
Main Symptoms and Types of Rosacea
Rosacea manifests with diverse cutaneous manifestations that can range from mild redness to pronounced inflammatory elements and skin texture changes [5]. There are four main subtypes of rosacea, which can exist either separately or in combination:
- Erythematotelangiectatic subtype (ETR): Characterized by persistent facial redness, especially on the cheeks, nose, forehead, and chin. Often accompanied by visible dilated blood vessels (telangiectasias) and a burning or stinging sensation.
- Papulopustular subtype (PPR): In addition to redness, small red bumps (papules) and pus-filled pimples (pustules) appear, resembling acne but without comedones.
- Phymatous subtype: A rare but severe subtype more commonly seen in men. It leads to skin thickening and irregularities, especially on the nose (rhinophyma), ears (otophyma), or chin.
- Ocular subtype: Affects the eyes, causing dryness, burning, itching, a gritty sensation in the eyes, redness of the conjunctiva and eyelids, as well as chalazions or styes.
Early diagnosis and timely initiation of treatment are important to prevent disease progression and the development of complications [3].
Diagnosis of Rosacea: How to Distinguish It from Other Conditions
The diagnosis of rosacea is based on the clinical picture and medical history. There are no specific laboratory tests to confirm the diagnosis. A dermatologist performs a thorough skin examination, assessing the nature of the redness, the presence of spider veins, papules, and pustules. It is important to rule out other skin diseases with similar symptoms, such as acne, seborrheic dermatitis, systemic lupus erythematosus, photodermatitis, or allergic contact dermatitis. In some cases, dermoscopy or a skin biopsy may be required for differential diagnosis. Evaluating the patient's medical history, including factors that provoke flare-ups, plays a key role in making an accurate diagnosis and choosing treatment tactics [8].
Modern Approaches to Treating Rosacea and Couperose
Treatment of rosacea and couperose requires a comprehensive approach aimed at reducing inflammation, eliminating redness and vascular changes, and preventing flare-ups. The efficacy and safety of various therapy methods are constantly being studied [4, 6].
Medical treatment:
- Topical medications:
- Metronidazole: Has anti-inflammatory and antimicrobial effects, effective for the papulopustular subtype.
- Azelaic acid: Reduces inflammation and redness, has antibacterial properties.
- Ivermectin: Effective against the Demodex mite, which plays a role in the pathogenesis of rosacea.
- Brimonidine and oxymetazoline: Vasoconstrictors that temporarily reduce redness.
- Systemic medications:
- Antibiotics (e.g., low-dose doxycycline): Have anti-inflammatory effects, used for pronounced papulopustular subtype.
- Isotretinoin: Can be used in low doses for severe, resistant forms of rosacea, especially the phymatous subtype.
Device-based methods:
- Laser therapy (IPL, PDL): Considered the "gold standard" for removing dilated vessels (telangiectasias) and reducing persistent redness. Lasers selectively target hemoglobin in blood vessels, coagulating them without damaging the surrounding skin.
- Electrocoagulation: Used to remove individual large vessels.
The choice of treatment method depends on the rosacea subtype, severity, individual patient characteristics, and response to therapy. Combination therapy is sometimes required to achieve the best results [7].
Prevention and Maintenance Therapy
Successful management of rosacea includes not only treating active manifestations but also long-term prevention of flare-ups. Key aspects of maintenance therapy include:
- Trigger avoidance: Identification and exclusion of individual provoking factors (sun, alcohol, spicy food, stress).
- Proper skin care: Use of gentle cleansers, moisturizers, and high-SPF sunscreens (at least 30) daily. Avoiding aggressive scrubs, alcohol-based lotions, and products with irritating ingredients.
- Sun protection: Mandatory use of sunscreens and hats when going outside.
- Diet: Some patients note improvement when eliminating certain foods. Keeping a food diary can help identify individual triggers.
- Regular dermatologist visits: To assess skin condition, adjust therapy, and prevent relapses.
Long-term adherence to treatment and preventive measures plays a decisive role in maintaining remission and improving the quality of life for rosacea patients [1, 2].
