Rosacea and facial flushing

Rosacea is a long term inflammatory skin condition that mainly affects the face. It often causes redness, flushing, visible blood vessels, and sometimes spots. Symptoms can come and go and may worsen over time if not managed.

This page explains the features of rosacea, common triggers, treatment options, and when to seek GP advice.

These articles are intended as educational sources, not diagnostic nor taking place of a proper medical assessment. If you need help with skin concerns, please book an appointment. We also offer specialist GP dermatology input at the Skin Clinic.

Symptoms of rosacea

Rosacea symptoms vary between individuals and may include:

Persistent facial redness, especially on the cheeks, nose, forehead, and chin
Episodes of flushing or blushing
Small red bumps or pus filled spots
Visible blood vessels on the skin surface
Burning, stinging, or sensitive skin
Dry or rough skin texture

Some people also develop eye symptoms, known as ocular rosacea.

Urgent symptoms and red flags

Seek urgent medical advice if you develop:

Eye pain, redness, or blurred vision
Severe swelling of the face or eyelids
Rapid worsening of symptoms with feeling unwell

Eye involvement may indicate ocular rosacea and requires prompt assessment.

Common causes and triggers

The exact cause of rosacea is not fully understood. It is thought to involve inflammation, blood vessel sensitivity, and immune system changes.

Common triggers include:

Sun exposure
Hot drinks and spicy foods
Alcohol
Stress or anxiety
Heat, cold, or wind
Certain skincare products

Identifying and avoiding personal triggers can help reduce flare ups.

How a GP assesses rosacea

A GP can usually diagnose rosacea based on symptoms and appearance. During an assessment, they may ask about:

Pattern and duration of redness or flushing
Skincare routine and products used
Triggers that worsen symptoms
Eye irritation or dryness
Previous treatments tried

Photographs and video consultations are often sufficient for remote assessment.

Investigations

Most people with rosacea do not need investigations.

Tests may be considered if the diagnosis is unclear or if symptoms suggest another skin condition.

Self care and lifestyle measures

Self care plays an important role in managing rosacea:

Use gentle, fragrance free cleansers
Avoid harsh exfoliation or scrubs
Apply daily sunscreen suitable for sensitive skin
Identify and avoid known triggers
Keep skincare routines simple and consistent

Improvement is gradual and flare ups are common.

Medical treatments a GP may recommend

Depending on symptoms, a GP may recommend:

Topical treatments to reduce redness and inflammation
Oral treatments for more persistent symptoms
Advice on skincare products suitable for rosacea prone skin

Treatment aims to control symptoms rather than cure the condition.

When to seek GP review

You should consider a GP appointment if:

Facial redness or flushing is persistent
Symptoms are worsening or affecting confidence
You have frequent flare ups
Over the counter products are not helping
You develop eye symptoms

Early treatment can help prevent progression.
