What is rosacea?
Rosacea is a long-term inflammatory skin condition primarily affecting the face. It causes persistent redness, visible blood vessels, and sometimes acne-like bumps. The exact cause is not fully understood, but it involves an overactive immune response, skin barrier dysfunction, and sometimes microbial imbalance on the skin.
Rosacea typically affects adults between 30–50 years old, more commonly in fair-skinned individuals. While it is not contagious, it can significantly impact confidence, social interactions, and quality of life, particularly if left untreated.
What causes rosacea?
Rosacea arises from a combination of genetic, environmental, and immune factors.
Key contributing factors:
- Genetic predisposition (family history of rosacea)
- Abnormal blood vessel regulation leading to flushing
- Overactive immune response causing inflammation
- Skin mites (Demodex folliculorum) and bacterial factors
Common triggers:
- Sun exposure
- Hot drinks or spicy foods
- Alcohol
- Extreme temperatures (heat or cold)
- Stress or emotional triggers
- Certain skincare products or harsh chemicals
What are the common symptoms of rosacea?
- Persistent redness across the cheeks, nose, forehead, or chin
- Small visible blood vessels (telangiectasia)
- Red, acne-like bumps or pustules
- Eye irritation (dryness, watery eyes, or redness
- Burning or stinging sensations
- Thickened skin in severe cases (usually on the nose, rhinophyma)
Symptoms often flare and then improve, but redness and flushing can become permanent over time.
How is rosacea diagnosed?
A GP will usually diagnose rosacea through a detailed assessment:
- History of symptoms, triggers, and duration
- Visual inspection of the skin
- Discussion of eye symptoms if present
Online GP consultations are suitable for initial assessment, particularly to review triggers, symptoms, and impact on daily life. In-person evaluation may be required if:
- Diagnosis is uncertain
- Severe inflammation or thickened skin develops
- Eye involvement requires specialist ophthalmology review
How long does rosacea last?
Rosacea is chronic and can last for years, often following a relapsing and remitting course. Severity varies from mild facial redness to more persistent inflammation. Effective management and trigger avoidance can significantly reduce flare-ups.
Is rosacea contagious?
No, rosacea cannot be passed from person to person.
