Rosacea causes and treatment UK is an important topic for people experiencing persistent facial redness, flushing or sensitive skin. Rosacea is a long-term skin condition that commonly affects the cheeks, nose, forehead and chin. It can also cause visible blood vessels, burning sensations and acne-like bumps, with symptoms that may flare up and settle over time.
Although rosacea cannot currently be cured, appropriate skincare, identifying personal triggers and prescribed treatments can help control symptoms.
In the UK, people concerned about persistent facial redness can contact their GP for an assessment and treatment advice. Understanding what causes flare-ups, which products may irritate the skin and when to seek medical help can make rosacea easier to manage.
Quick answer: Rosacea is a chronic inflammatory skin condition associated with facial redness, flushing and sometimes spots or visible blood vessels. Its exact cause is not fully understood, but heat, sunlight, alcohol, spicy foods and stress can trigger symptoms in some people. Gentle skincare, daily sun protection and suitable medical treatment can help manage it.
What Is Rosacea?
Rosacea is a chronic skin condition that mainly affects the central face. It often develops gradually and may initially appear as occasional flushing before becoming more persistent.
People with rosacea may experience:
- Persistent redness on the cheeks, nose, chin or forehead.
- Episodes of flushing, particularly after exposure to heat or sunlight.
- Small red bumps or pus-filled spots.
- Visible blood vessels near the surface of the skin.
- Dryness, stinging, burning or increased skin sensitivity.
- Eye irritation, including gritty, dry or watery eyes.
Not everyone experiences every symptom. Rosacea can also resemble other skin conditions, including acne and eczema, so an appropriate assessment is important.
If your skin is itchy, dry or inflamed, our guide to eczema flare-ups and treatment options explains another common condition that can cause skin irritation.
What Causes Rosacea?
The exact cause of rosacea is not fully understood. Research suggests that several factors may contribute to its development, including inflammation, changes in facial blood vessel responses, skin-barrier function and immune-system activity.
Potential contributing factors include:
1. Genetic susceptibility
Rosacea sometimes runs in families, suggesting that inherited factors may influence a person’s likelihood of developing it. However, having a family history does not mean that you will necessarily develop the condition.
2. Inflammation and immune responses
Changes in the skin’s inflammatory response may contribute to redness, swelling and acne-like bumps associated with rosacea.
3. Facial blood vessel sensitivity
People with rosacea may experience exaggerated blood vessel responses to heat, sunlight, exercise or other triggers. This can cause flushing and, over time, visible blood vessels.
4. Skin-barrier sensitivity
Rosacea-prone skin may react strongly to products that other people tolerate comfortably. Harsh cleansers, abrasive exfoliants and fragranced products can worsen irritation.
5. Microscopic skin mites and other factors
The naturally occurring Demodex mites found on human skin may play a role in some cases of rosacea. However, their presence alone does not establish the diagnosis, and rosacea is not simply caused by poor hygiene.
Important: Rosacea is not contagious. It is not caused by being unclean, and ordinary contact with someone who has rosacea will not transmit the condition.
What Are the Most Common Rosacea Triggers?
Rosacea triggers vary between individuals. A product, food or activity that causes a flare-up for one person may have little effect on someone else.
Common triggers include:
Sunlight and UV exposure
Sun exposure can worsen facial redness and trigger flushing. Protect your skin with broad-spectrum SPF 30–50 sunscreen, shade and a wide-brimmed hat when appropriate.
Heat and hot drinks
Hot weather, saunas, hot baths and very hot drinks may trigger flushing. Try cooler showers and allow hot drinks to cool before drinking them.
Spicy foods and alcohol
Chilli, spicy meals and alcohol can worsen symptoms in some people. Identify your own reactions instead of automatically eliminating entire food groups.
Exercise and temperature changes
Intense exercise, cold winds and sudden changes between indoor and outdoor temperatures may trigger redness. Consider cooler environments and adjust exercise intensity when needed.
Stress and emotional changes
Stress, embarrassment and anxiety may contribute to flushing. Relaxation techniques, regular sleep and manageable activity may help you cope with flare-ups.
Other potential triggers include harsh skincare products, fragranced cosmetics and certain medications. Do not stop prescribed medication without speaking to your healthcare professional.
Keeping a simple diary of symptoms, products, weather conditions and meals can help you identify patterns over time.
How to Build a Rosacea-Friendly Skincare Routine
A consistent, gentle routine is often more helpful than using multiple active ingredients. The aim is to protect the skin barrier, reduce irritation and limit sun-related flare-ups.
Morning routine
Step 1: Cleanse gently
Use lukewarm water and a mild, fragrance-free cleanser. Avoid scrubbing brushes, rough washcloths and very hot water.
Step 2: Apply moisturiser
Choose a gentle, non-comedogenic moisturiser suited to sensitive skin. Patch-test new products before applying them more widely.
Step 3: Use sunscreen
Apply broad-spectrum SPF 30–50 sunscreen daily. If chemical filters sting, you could ask a pharmacist about trying a fragrance-free mineral sunscreen containing zinc oxide or titanium dioxide.
Evening routine
- Gently remove sunscreen and makeup with a mild cleanser.
- Apply your prescribed rosacea treatment if directed to use it at this time.
- Finish with a moisturiser to help maintain the skin barrier.
Introduce new products one at a time. Avoid abrasive scrubs, strong exfoliating acids and irritating products containing fragrance if they trigger symptoms.
Products containing retinoids or benzoyl peroxide may irritate rosacea-prone skin, so seek professional advice before using them to treat facial redness or acne-like bumps.
Which skincare ingredients are suitable for rosacea?
| Ingredient or product | General advice |
|---|---|
| Glycerin and ceramides | Can help support skin hydration and barrier function. |
| Zinc oxide or titanium dioxide | Sunscreen filters that some people with sensitive skin find easier to tolerate. |
| Fragrance-free moisturisers | Often a useful starting point for sensitive skin. |
| Azelaic acid | May help some rosacea symptoms, but can cause stinging and is best introduced with appropriate advice. |
| Strong exfoliating acids and abrasive scrubs | May worsen irritation; generally best avoided during flare-ups. |
| Alcohol-heavy or strongly fragranced products | Can irritate some people; check the full formulation and your own response. |
No single product works for everyone. Stop using a product if it causes significant irritation and seek advice if symptoms persist.
What Treatments Are Available for Rosacea on the NHS?
Treatment depends on the symptoms, their severity and whether the eyes are affected. A GP can often diagnose rosacea by examining the skin and discussing your symptoms and triggers.
Depending on the presentation, treatment options may include:
- Topical medicines: Prescription creams or gels such as ivermectin, metronidazole or azelaic acid may be recommended for inflammatory bumps and spots.
- Oral antibiotics: A course of an oral antibiotic, sometimes doxycycline, may be prescribed for more significant inflammation or certain eye-related symptoms.
- Treatment for persistent redness: Brimonidine or oxymetazoline may be considered in appropriate cases where available and suitable. These medicines can have side effects, including worsening redness in some people.
- Laser or light-based treatment: Certain procedures may reduce visible blood vessels and persistent redness. Access, suitability and funding vary.
- Eye care: Eye symptoms may require lubricating drops, eyelid care or assessment by an eye-care professional.
Not every treatment is suitable for every patient, and availability can vary across the UK. NHS-funded cosmetic procedures are not routinely available in all circumstances.
For information on accessing primary care, read our guide on how to register with a GP in the UK.
When to seek help: Arrange a GP appointment if facial redness persists, you develop recurrent bumps, your skin becomes increasingly uncomfortable or you are unsure whether the problem is rosacea. Seek urgent same-day medical advice for eye pain, light sensitivity, blurred vision or a painful red eye, as these symptoms may indicate a problem requiring prompt treatment.
Rosacea vs Acne: What Is the Difference?
Rosacea and acne can both cause facial bumps, but they have different patterns and may require different treatments.
| Feature | Rosacea | Acne |
|---|---|---|
| Typical location | Central face, especially cheeks and nose | Face, chest, shoulders and back |
| Redness and flushing | Common | Not usually characterised by recurrent flushing |
| Blackheads and whiteheads | Not typical | Common |
| Visible blood vessels | Can occur | Not a typical feature |
| Skin sensitivity | Often increased | Varies by person |
| Treatment | May include rosacea-specific topical medicines | May include acne-specific topical or oral treatments |
Some people can have both conditions. Avoid assuming that every facial spot is acne, because using the wrong treatment may increase irritation.

Can Rosacea Be Cured Permanently?
There is currently no permanent cure for rosacea, but many people can manage it successfully.
Symptoms may improve with appropriate treatment, gentle skincare and trigger management. However, flare-ups can return, so long-term care is often necessary.
A practical management plan includes:
- Following a consistent skincare routine.
- Wearing sunscreen every day.
- Identifying and managing personal triggers.
- Using prescribed treatments as directed.
- Seeking a review if symptoms worsen or treatment stops working.
Persistent redness or visible blood vessels may not respond fully to creams, even when inflammatory bumps improve. A healthcare professional can discuss other options where appropriate.
How Can You Manage Rosacea Flare-Ups in the UK?
The UK’s weather can change considerably between seasons. Cold winds, indoor heating, warm summers and sudden temperature changes may affect rosacea-prone skin.
Consider the following practical steps:
During colder months: Protect your face from harsh winds with a soft scarf, use a moisturiser that you tolerate well and avoid very hot showers.
During warmer months: Use broad-spectrum sunscreen, seek shade and try to avoid overheating during exercise.
When using indoor heating: Avoid sitting too close to direct heat sources if they trigger flushing. Keep your skincare routine gentle.
When shopping for skincare: Look for fragrance-free products designed for sensitive skin. Remember that product labels do not guarantee that a formulation will suit everyone.
When symptoms affect your wellbeing: Rosacea can affect confidence and social comfort. If ongoing stress is becoming difficult to manage, our article on how stress affects the body offers further information.
When Should You See a GP About Rosacea?
Contact your GP if you experience persistent facial redness, recurring inflammatory bumps, visible blood vessels or symptoms that do not improve with gentle skincare.
You should also seek advice if:
- Your symptoms are worsening or affecting daily life.
- Over-the-counter products repeatedly irritate your skin.
- You develop dry, gritty or uncomfortable eyes.
- You are uncertain whether you have rosacea, acne or another skin condition.
- You want to discuss prescription treatments or referral options.
Eye pain, blurred vision and light sensitivity need urgent assessment rather than routine skincare changes.
A GP can assess your symptoms and discuss treatment. If the diagnosis is uncertain, symptoms are severe or treatment is unsuccessful, referral to a dermatologist may be appropriate.
Frequently Asked Questions About Rosacea
1. What is the main cause of rosacea?
There is no single confirmed cause. Rosacea is thought to involve a combination of genetic susceptibility, inflammation, blood vessel responses and skin-barrier factors. Environmental and lifestyle triggers can make symptoms worse.
2. What foods should you avoid if you have rosacea?
There is no universal rosacea diet. Spicy foods, hot drinks and alcohol can trigger symptoms in some people. Track your own reactions and avoid restricting foods unnecessarily.
3. Is rosacea a lifelong condition?
Rosacea is generally a long-term condition. Symptoms can improve and flare up again, but appropriate treatment, sun protection and gentle skincare can help control it.
4. What is the best skincare routine for rosacea?
A simple routine typically includes a gentle cleanser, fragrance-free moisturiser and daily broad-spectrum sunscreen. Prescription treatment may be needed for inflammatory symptoms. Introduce products gradually and stop anything that causes significant irritation.
5. Can I get rosacea treatment on the NHS?
Yes. A GP can assess symptoms and prescribe suitable treatments when clinically appropriate. Access to specialist care and procedures varies, and cosmetic treatments may not be NHS-funded.
6. Is rosacea the same as acne?
No. Rosacea can cause red bumps and spots, but blackheads and whiteheads are more characteristic of acne. A clinician can help distinguish the two conditions.
7. Does stress cause rosacea?
Stress is not established as the sole cause of rosacea, but emotional stress can trigger flushing or worsen symptoms in some people.
8. When should I seek urgent help for rosacea?
Seek urgent same-day medical assessment if you develop eye pain, sensitivity to light, blurred vision or a painful red eye. These symptoms may indicate an eye problem that needs prompt treatment.
Conclusion
Rosacea can be frustrating, particularly when redness and flare-ups affect confidence or comfort. Although there is no permanent cure, recognising personal triggers, protecting the skin from sunlight, following a gentle skincare routine and seeking appropriate treatment can make a meaningful difference.
If facial redness persists or your symptoms are affecting your quality of life, speak to your GP rather than relying on skincare products alone. Early assessment can help identify the condition and establish a suitable management plan.
