Rosacea is a long-term inflammatory skin condition that mainly affects the central face. It can cause persistent redness, flushing, visible blood vessels and acne-like bumps. Symptoms often flare for weeks or months and then improve. Rosacea cannot be cured, but it can usually be controlled with the right routine and treatment.

This guide explains what rosacea is, how it usually shows up, what commonly triggers flare-ups, and how rosacea is typically treated in the UK.

Quick definition

Rosacea is not the same as acne, and it is not caused by poor hygiene. It is a chronic condition that tends to come and go. Many people notice that their skin is calmer for a while, then flares again after a trigger (for example heat, sun, alcohol or harsh skincare).

Is rosacea contagious? No. Rosacea is not contagious. You cannot catch it from another person and you cannot pass it on by touch.

What does rosacea look and feel like?

Rosacea can look different from person to person, but most symptoms happen on the cheeks, nose, chin and forehead. Common signs include:

Persistent facial redness (especially cheeks and nose)
Flushing or blushing that comes and goes
Visible small blood vessels (thread veins)
Small bumps and pus-filled spots that can resemble acne
Burning, stinging, dryness or sensitivity
Rough texture or scaling in flare periods

Some people also develop symptoms around the eyes (dryness, irritation, gritty feeling) which can happen before, after, or along with skin symptoms. Eye involvement is called ocular rosacea and should be taken seriously.

Rosacea types (subtypes)

Rosacea is often grouped into types based on the dominant feature: redness, bumps, thickening, or eye symptoms.

Type	Typical signs	Common focus
Erythematotelangiectatic (ETR)	Persistent redness, flushing, visible vessels	Reduce redness + protect barrier
Papulopustular	Redness plus bumps/spots (acne-like)	Calm inflammation + treat bumps
Phymatous	Skin thickening, enlarged pores; often nose (rhinophyma)	Early specialist review + procedures
Ocular	Dry/irritated eyes, lid inflammation, gritty feeling	Eye care + clinician assessment

It is common to have features of more than one type. For example, someone can have long-term redness and also get flare-ups of bumps.

What causes rosacea?

There is no single proven cause, but rosacea is linked to a mix of inflammation, increased blood vessel reactivity, and a weakened skin barrier. Some people also have a stronger inflammatory response to Demodex mites (microscopic organisms that naturally live on skin), which may contribute to symptoms in certain cases.

Risk factors and patterns that are often seen include:

Family tendency (it can run in families)
Fair skin (but it can affect all skin tones; redness may be harder to see on deeper skin tones)
Adults (often starts between 30 and 50, but can occur earlier or later)
Long-term trigger exposure (sun, heat, harsh skincare) that repeatedly provokes flushing and inflammation

Rosacea is not caused by dirt, and over-washing or using strong acne products can make symptoms worse by damaging the skin barrier.

Common rosacea triggers (flare checklist)

Triggers differ between people, so it helps to track what happens before a flare. The most common trigger categories include:

Sun exposure (UV)
Heat (hot weather, saunas, hot showers) and sudden temperature changes
Cold wind (winter exposure)
Alcohol (especially red wine for some people)
Spicy foods or very hot drinks
Stress, anxiety or embarrassment flushing
Exercise that raises core temperature quickly
Harsh skincare (fragrance, alcohol-based products, scrubs, strong acids)
Topical steroid creams on the face (can cause steroid-induced rosacea)

Practical step: keep a simple trigger diary for 2 to 3 weeks. Note the date, exposures (sun, heat, alcohol), symptoms (redness, bumps, burning), and what helped. Over time you will find your repeat patterns.

How rosacea is diagnosed (and what it can be confused with)

Rosacea is usually diagnosed clinically by pattern recognition: where the redness sits, whether flushing happens, whether there are visible vessels, and whether bumps appear without blackheads/whiteheads.

It can be confused with acne, eczema/dermatitis, perioral dermatitis, contact allergy, or lupus rash. If you are unsure, a clinician can review photos and symptoms to confirm the diagnosis and choose the best treatment pathway.

How rosacea is treated in the UK

Rosacea treatment usually combines three layers: (1) trigger control, (2) a gentle routine that supports the skin barrier, and (3) targeted treatment for the dominant symptoms (bumps or redness).

Treatment options are chosen based on symptoms:

Dominant symptom	Typical treatment direction	Notes
Bumps/spots (papules/pustules)	Prescription topicals such as azelaic acid, metronidazole, or ivermectin	Often used for weeks to months; routine matters
Persistent redness/flushing	Redness reducers (for example brimonidine) + trigger control; sometimes laser/IPL	Redness products control appearance; routine prevents rebound
Visible vessels	Laser/IPL procedures	Topicals have limited effect on fixed vessels
Eye symptoms	Eye care + clinician review (may need oral antibiotics)	Seek help if pain or vision changes

Treatments for bumps and spots (papules/pustules)

If your rosacea is mainly bumps and acne-like spots, topical medicines are commonly used to calm inflammation and reduce lesions. Examples of prescription options include:

Azelaic acid gel (Finacea 15% Gel):
Metronidazole gel (Metrogel 0.75%):
Metronidazole gel (Rozex 0.75%):
Ivermectin cream (Soolantra 1%):

Which one is used depends on your symptom pattern, your skin sensitivity, and what has (or has not) worked before. A clinician may also recommend an oral antibiotic course in some cases, particularly for more inflamed flare-ups.

Treatments for persistent redness and flushing

If redness is the main issue, the strategy is usually: remove triggers, protect the barrier, and consider targeted redness control.

A prescription option used for facial erythema is brimonidine gel (Mirvaso 0.33%)

Brimonidine works by narrowing superficial blood vessels, which can temporarily reduce visible redness. It is not a cure; it is a symptom-control tool.

For fixed thread veins (telangiectasia), procedures such as laser or intense pulsed light (IPL) are often discussed with a dermatologist.

How long does treatment take?

Rosacea improves in stages. Many people notice reduced burning and sensitivity first, then fewer flare days, then fewer bumps or less visible redness. A practical expectation is to review progress after several weeks of consistent use, and adjust if needed. The goal is control and maintenance, not a one-off cure.

Daily routine: gentle skincare that supports treatment

A simple routine reduces background inflammation and helps prescription treatments work better:

Cleanse: use a gentle, fragrance-free cleanser with lukewarm water
Treat: apply your prescribed gel/cream as directed (thin layer, avoid over-application)
Moisturise: use a barrier-support moisturiser (helps dryness and stinging)
Protect: apply daily broad-spectrum SPF to reduce UV-triggered flares

Avoid scrubs, strong acids, alcohol-heavy toners and frequent product switching. If you want to try new products, introduce one change at a time so you can identify irritation early.

When to seek urgent help

Seek clinician advice promptly if you have any of the following:

Eye pain, light sensitivity, blurred vision, or severe eyelid inflammation
Rapid worsening despite avoiding triggers and following treatment
Skin thickening of the nose or other areas (possible phymatous rosacea)
Severe burning, swelling, or signs of infection

If you are unsure whether your symptoms are rosacea or another condition, a clinician assessment is the safest next step.

FAQs

Can rosacea be cured?

Rosacea cannot be cured, but it can usually be controlled. Many people reach long periods of calm skin with the right routine and treatment plan.

Does rosacea go away on its own?

It can improve temporarily, but without management it often returns. Early treatment can help prevent worsening.

Is rosacea the same as acne?

No. Rosacea can look acne-like, but it usually has flushing and central facial redness. Rosacea spots often occur without blackheads/whiteheads.

What is the biggest trigger for rosacea?

Sun and heat are common triggers, but the biggest trigger differs by person. A trigger diary is the fastest way to identify your pattern.

Can skincare cause rosacea flare-ups?

Yes. Fragrance, alcohol-based products, scrubs and strong acids can irritate the barrier and trigger burning and redness.

Should I use steroid cream on rosacea?

Do not use topical steroids on the face unless a clinician tells you to. Steroids can worsen rosacea or cause steroid-induced rosacea.

What treatment helps rosacea bumps the most?

Prescription topicals such as azelaic acid, metronidazole or ivermectin are commonly used. The best option depends on your skin and severity.

What treatment helps redness the most?

Trigger control and daily SPF help long-term. Targeted redness control (for example brimonidine) can reduce visible redness temporarily. Laser/IPL can help thread veins.

How quickly do prescription creams work?

Some improvement may be seen in a few weeks, but full benefit often takes longer. Consistency and routine are key.

Can rosacea affect the eyes?

Yes. Ocular rosacea can cause dryness, irritation and lid inflammation. Seek help quickly if pain or vision changes occur.

Is rosacea contagious?

No. You cannot catch or spread rosacea.

When should I see a GP or dermatologist?

If symptoms are persistent, affecting confidence, or not improving with routine changes, get assessed. Seek urgent help for eye symptoms or thickening of skin.
