Rosacea

Rosacea is a chronic skin condition that primarily affects the face, particularly the cheeks, nose, chin, and forehead. It is characterised by redness, inflammation, and visible blood vessels, with symptoms that can vary from person to person. The cause of rosacea is unclear, but it's believed to result from a mix of genetic, environmental, and immune factors. Understanding the nature of this condition is crucial for those seeking effective management and treatment options.

What Is Rosacea?

Rosacea is a long-term inflammatory skin condition that causes redness and a rash, typically on the nose and cheeks. In some cases, it may also affect the eyes, leading to symptoms such as redness, itching, and watery discharge. The symptoms of rosacea can be intermittent, with many individuals experiencing flare-ups triggered by various factors. This includes sun exposure, emotional stress, and certain foods or drinks. Recognising the signs and symptoms of rosacea is essential for prompt diagnosis and appropriate treatment.

Rosacea can be classified into several distinct types, each with its own set of symptoms:

• Erythematotelangiectatic Rosacea (ETR): This type is characterised by persistent redness on the face and visible blood vessels under the skin. Without treatment, the redness may worsen or become permanent.

• Papulopustular Rosacea (PPR): PPR causes pus-filled bumps and swollen red bumps that resemble acne. This can appear on the forehead, cheeks, chin, and sometimes the scalp, chest, or neck.

• Phymatous Rosacea: This rare type causes the skin to thicken and scar. It typically affects the nose, leading to a swollen, bumpy, and sometimes discoloured appearance.

• Ocular Rosacea: When rosacea affects the eyes, it can irritate, bloodshot or watery appearance, dryness, and sensitivity. Cysts may also form on the eyelids.

• Prerosacea and Vascular Rosacea: Prerosacea involves frequent episodes of blushing and flushing of the face and neck. Vascular rosacea is characterised by swelling of blood vessels under the facial skin, leading to swollen, warm skin, commonly seen in women.

• Inflammatory Rosacea and Rhinophyma: Inflammatory rosacea is marked by the appearance of pimples. Rhinophyma, a severe form of phymatous rosacea, affects the nose, causing it to become enlarged, bulbous, and red.

Recognising the specific type of rosacea is crucial for determining the most appropriate course of treatment and management. Early diagnosis and intervention can help prevent the progression of the condition and minimise its impact on an individual's quality of life.

Rosacea is a chronic skin condition that primarily affects the face, causing a range of symptoms that can vary in severity. Some of the most common signs and symptoms of rosacea include:

• Facial Redness: A persistent flush or redness on the cheeks, nose, chin, and forehead, which may resemble a blush or sunburn that does not go away.

• Visible Blood Vessels: Small blood vessels (telangiectasias) become visible on the cheeks, nose, and other areas of the central face.

• Pustules and Bumps: Red or pus-filled bumps (papules and pustules) that may resemble acne, but without blackheads.

• Skin Thickening: The skin may thicken and enlarge due to excess tissue. This occurs most commonly on the nose (rhinophyma), and in severe cases, can cause facial disfigurement and obstruct nasal airflow.

• Eye Irritation (Ocular Rosacea): The eyes may become irritated, red, itchy, watery, or dry, with possible styes and crusts around the eyelids or eyelashes.

• Burning, Stinging, and Sensitivity: The skin may feel hot, tender, and sensitive to the touch.

• Flushing: Frequent blushing or flushing, often an early feature of the disorder.

If you experience any of these rosacea symptoms, it's essential to consult a dermatologist for an accurate diagnosis and appropriate treatment plan. Understanding the causes of rosacea can also help in managing the condition effectively.

While the exact cause of rosacea remains unknown, several factors are believed to contribute to its development:

• Genetics: A family history of rosacea may increase the risk of developing the condition. Certain genetic predispositions may make individuals more susceptible to the disorder.

• Environmental Factors: Exposure to various environmental triggers, such as sunlight, extreme temperatures, and emotional stress, may exacerbate rosacea symptoms and cause flare-ups. Identifying and avoiding these triggers can help in managing the condition.

• Microbes: Certain micro-organisms on the skin, particularly the Demodex folliculorum mite, have been associated with rosacea. These microbes may contribute to the inflammation and skin irritation characteristic of the disorder.

• Immune System Overactivity: An overactive immune system response may play a role in the development of rosacea. The immune system's excessive reaction to various triggers can lead to inflammation and the manifestation of rosacea symptoms.

Although the precise causes of rosacea are still being researched, understanding these potential contributing factors can aid in preventing and managing of the condition. Knowing your risk factors for developing rosacea is also crucial in taking proactive steps to maintain healthy skin.

Certain individuals may be at a higher risk of developing rosacea due to various factors, including:

• Age: Rosacea typically begins after age 30 and is more common among middle-aged and older adults. The risk of developing the condition increases with age.

• Skin Type: People with fair skin are more likely to develop rosacea, but it can also affect darker-skinned individuals. Those with sensitive skin or a history of sun damage may be at a higher risk.

• Family History: Having a family member with rosacea increases the likelihood of developing the condition, suggesting a genetic component to the disorder.

• Gender: While rosacea affects both men and women, it is more common in women, particularly during menopause. However, men are more likely to develop severe forms of the condition, such as rhinophyma.

• Lifestyle Factors: Certain lifestyle habits, like excessive alcohol consumption and smoking, may raise the risk of developing rosacea. Exposure to extreme temperatures or sunlight can also worsen its symptoms.

Understanding your risk factors for rosacea can help you take preventive measures and seek early intervention if symptoms appear. Working closely with a dermatologist can help you develop a personalised plan to manage your rosacea and maintain healthy, clear skin.

Rosacea can lead to several complications if left untreated or not managed properly.

• Ocular Complications: Ocular rosacea affects over 50% of patients with rosacea and can cause significant eye problems. This includes dryness, redness, tearing, light sensitivity, and blurred vision.

• Keratitis Risk: Severe cases can lead to keratitis, an inflammation of the cornea. This can result in corneal ulceration and infection, potentially threatening vision.

• Rhinophyma: In severe cases, rosacea can also cause the skin to thicken, particularly on the nose. This leads to a condition known as rhinophyma, resulting in an enlarged, bulbous nose appearance, which is more common in men.

• Morbihan Disease: A rare variant of rosacea, known as Morbihan disease, can cause facial lymphoedema. It results in redness and swelling of the face and eyelids.

• Psychological Impact: Rosacea can also have a significant psychological impact, leading to anxiety, depression, and embarrassment, affecting the patient's quality of life.

• Systemic Conditions: Rosacea is linked to several systemic conditions. These include neurological diseases, inflammatory bowel disease, cardiovascular issues, hypertension, and dyslipidemia. It's also associated with diabetes mellitus, migraines, and rheumatoid arthritis. However, more research is necessary to fully understand these connections.

Preventing rosacea complications is crucial, and several measures can help manage and reduce the frequency and severity of symptoms.

While there is no definitive way to prevent rosacea, several measures can help manage and reduce the frequency and severity of symptoms.

• Avoid Triggers: Identify and avoid common triggers like UV rays, extreme temperatures, spicy foods, alcohol, stress, and irritating skincare.

• UV Protection: Use sunscreens with at least SPF 30 and wear protective clothing to minimise UV exposure.

• Gentle Skincare: Follow a consistent skincare routine with gentle cleansers and avoid harsh products.

• Track Flare-ups: Keep a diary to identify personal triggers and manage symptoms effectively.

• Treatment Adherence: Follow prescribed treatments, including medications and procedures like laser therapy, to control symptoms and prevent complications.

The diagnosis of rosacea is typically based on a clinical examination of the skin and a thorough patient history.

• Clinical Examination: Dermatologists check for signs like facial redness, visible blood vessels, papules, and pustules. They may ask about triggers.

• Ruling Out Other Conditions: Tests may be done to exclude conditions like lupus, seborrheic dermatitis, or acne vulgaris.

• Skin Biopsy: A skin biopsy may be performed to examine the skin tissue under a microscope and confirm the presence of inflammation and other characteristic features of rosacea.

• Eye Examination: For ocular rosacea, an ophthalmologist may assess corneal damage, conjunctivitis, or blepharitis.

• Imaging Tests: In rare cases, CT scans or MRIs may be used to evaluate phymatous changes, particularly in rhinophyma.

Managing rosacea involves a combination of lifestyle changes, skincare routines, and medical treatments.

• Gentle Skincare Routine: A gentle skincare routine is crucial for managing rosacea symptoms. Use a mild, fragrance-free cleanser specifically formulated for rosacea, and apply it gently with your fingertips using a circular motion. Rinse with warm water and pat the face dry with a clean cotton towel. After cleansing, moisturise your skin, especially if you are using medication for rosacea. Apply your medication first, followed by a rosacea-friendly moisturiser to help hydrate and comfort the skin.

• Sun Protection: Protect your skin from the sun year-round using a broad-spectrum sunscreen with at least SPF 30. Mineral sunscreens containing titanium dioxide or zinc oxide are recommended to avoid a white cast, especially on darker skin tones.

• Avoid Triggers: Identifying and avoiding triggers that can exacerbate rosacea is essential. Common triggers include extreme temperatures, stress, alcohol, spicy foods, and certain skincare products.

• Skincare Practices: Be gentle with your skin; avoid rubbing, scrubbing, or massaging, and refrain from using washcloths or facial sponges.

• Ocular Rosacea Care: If you have ocular rosacea, maintain good eyelid hygiene by using warm compresses and artificial tears as needed.

Also, avoid alcohol-based products and those containing skin irritants like alcohol, camphor, urea, and menthol. While lifestyle changes can help manage rosacea symptoms, medication may be necessary for more effective treatment.

Medication for rosacea

The choice of medication for rosacea depends on the severity and type of symptoms.

• Topical Treatments: Topical treatments are often used for the erythematotelangiectatic form of rosacea. These include metronidazole, azelaic acid, and brimonidine, which can be used alone or in combination to reduce erythema, papules, and pustules.

• Papulopustular Treatment: For the papulopustular form, a combination of topical therapies such as metronidazole, azelaic acid, and ivermectin may be prescribed. Sulfacetamide and sulfur lotion can also be effective for acne-like breakouts associated with rosacea.

• Oral Antibiotics: In more severe cases, oral medications may be necessary. Oral antibiotics like doxycycline or erythromycin may be prescribed for their anti-inflammatory effects. These are typically used for a short duration to minimise side effects.

• Isotretinoin: For severe rosacea that does not respond to other treatments, isotretinoin may be considered. However, this medication requires close monitoring due to potential side effects.

If you suspect you have rosacea or your symptoms are not improving with self-care measures, it's important to consult a dermatologist. Early diagnosis and treatment can help prevent the progression of rosacea and minimise its impact on your quality of life. See a doctor if you experience persistent redness, bumps, or pimples on your face, especially if they are accompanied by a burning or stinging sensation.

If your eyes are affected, causing redness, dryness, or irritation, seek medical attention promptly to prevent complications. Additionally, if your rosacea symptoms are causing emotional distress or affecting your self-esteem, don't hesitate to discuss your concerns with a healthcare professional. They can provide guidance on coping strategies and support groups.
