Understanding and managing rosacea
Rosacea is a long-term skin condition that primarily affects the face. It can cause significant physical discomfort and emotional distress if left untreated, but with the right care, its symptoms can be managed effectively. A proper understanding of the condition, its triggers, and available treatments can make a substantial difference to a person’s quality of life. In this article, a consultant dermatologist explains what causes rosacea and methods of managing it.
What is rosacea and what are the symptoms?
Rosacea often begins with flushing or persistent redness, typically across the nose, cheeks, chin, and forehead. Over time, small visible blood vessels (telangiectasia), papules and pustules (which can resemble acne), and a burning or stinging sensation may develop. In some people, especially men, thickening of the skin can occur, most commonly affecting the nose in a condition known as rhinophyma.
For patients with darker skin tones, rosacea may present differently. Rather than obvious redness, it may appear as darker patches, warmth, swelling, or dryness, which can sometimes delay diagnosis. It’s important for clinicians and patients alike to recognise that rosacea is not exclusive to fair skin, and may require a more nuanced clinical approach across deeper skin tones.
What causes rosacea?
The exact cause of rosacea is not fully understood, but it is thought to be related to a combination of genetic, environmental, vascular, and inflammatory factors. People with a family history of rosacea may be more likely to develop it themselves.
Several triggers have been identified that can exacerbate rosacea symptoms, including:
- Sun exposure
- Hot drinks or spicy foods
- Alcohol
- Stress
- Cold weather or wind
- Certain skincare products
- Hormonal fluctuations
In addition, research suggests a possible link between mites (tiny organisms that live on the skin) and rosacea, as well as an abnormal immune response in the skin.
Treatments for rosacea
Treatment for rosacea should be tailored to the individual, depending on the subtype and severity of their symptoms. While rosacea cannot be cured, it can be effectively managed with a combination of clinical care and self-management.
Topical treatments are often the first line of treatment and may include:
- Metronidazole gel or cream
- Azelaic acid, which can reduce inflammation and help fade redness
- Ivermectin, particularly useful where Demodex mite overgrowth is suspected
- Brimonidine gel, which works by constricting blood vessels to reduce facial redness temporarily
In more severe or resistant cases, oral antibiotics such as doxycycline may be prescribed, even at low doses, for their anti-inflammatory rather than antimicrobial properties. For people with ocular rosacea (which affects the eyes), specific treatments such as artificial tears or oral antibiotics may be required.
For patients with persistent redness or visible blood vessels, laser or light-based therapies such as intense pulsed light (IPL) or vascular laser treatments can be highly effective.
Lifestyle and skincare management
Alongside clinical treatments, identifying and avoiding personal triggers is essential. Keeping a symptom diary can help spot patterns and avoid flare-ups. People with rosacea should also be encouraged to use:
- Gentle, fragrance-free cleansers and moisturisers
- High-factor, broad-spectrum sun protection daily (SPF 50 or above)
- Non-comedogenic, non-irritating makeup if desired
Avoiding physical exfoliants, alcohol-based products, and heavy occlusive creams can also help reduce irritation. Stress management techniques, including relaxation therapy and regular exercise, may also benefit those with stress-related flare-ups.
Long-term outlook and follow-up
Rosacea is a chronic condition, and its course can vary widely between individuals. Some people may have only mild symptoms that occasionally flare, while others may require long-term treatment and ongoing dermatological care. Regular follow-up with a GP or dermatologist helps ensure that treatment remains effective and symptoms are well-controlled.
In conclusion, rosacea is a manageable condition, but it requires personalised treatment and patient education. With the right approach — combining medical treatment, lifestyle changes, and skin care — most people with rosacea can achieve excellent control of their symptoms and maintain confidence in their appearance.
