At a glance
- Rosacea is a common chronic condition causing facial redness, flushing and sometimes acne-like bumps.
- It mainly affects the central face — cheeks, nose, chin and forehead.
- It tends to flare with triggers such as heat, sun, spicy food and alcohol.
- It cannot be cured but is well controlled with treatment and trigger avoidance.
- It can also affect the eyes, so tell a doctor about any gritty, dry or irritated eyes.
Symptoms and subtypes
Rosacea can look quite different from person to person, and several patterns often overlap. Common features include persistent central-face redness, easy flushing or blushing, visible small blood vessels (telangiectasia), and papules and pustules that can resemble acne — but without the blackheads seen in acne. Many people also describe stinging, burning or a feeling of tightness, and skin that reacts easily to products or weather.
Doctors often describe rosacea by its main patterns rather than as a single disease:
- Flushing and redness — frequent blushing and lasting redness across the cheeks and nose.
- Bumps and pustules — inflamed spots that come and go, sometimes mistaken for adult acne.
- Visible blood vessels — fine thread-like vessels on the cheeks or around the nose.
- Skin thickening — over time, and more often in men, the skin of the nose can thicken and become bumpy (known as rhinophyma).
- Eye involvement (ocular rosacea) — dry, gritty, red or irritated eyes and inflamed lids, which can occur with or even before skin symptoms.
What causes it and common triggers
The exact cause of rosacea is not fully understood, but it is thought to involve a combination of blood-vessel reactivity, an overactive immune response, inherited tendencies, and skin microbes such as Demodex mites that normally live on the skin. It is more common in fair skin but occurs in all skin tones, and it is not caused by poor hygiene or by being unclean.
While these underlying factors set the stage, day-to-day flares are usually brought on by triggers. Common ones include:
- Sun and heat — particularly relevant in Singapore’s hot, humid climate.
- Hot drinks such as coffee and tea.
- Spicy food.
- Alcohol, especially red wine.
- Stress and strong emotions.
- Vigorous exercise and saunas or hot showers.
- Harsh or fragranced skincare and certain cosmetics.
Triggers vary a lot between individuals. Keeping a simple diary of flares can help you identify and reduce your own personal triggers, which is a key part of long-term control.
Who is at risk
Rosacea is common and can affect anyone, but some people are more prone to it. It most often appears in adults between about 30 and 50 years of age, and tends to be more noticeable in people with fair skin that flushes easily. It appears to run in some families, so a family history can increase the chance of developing it. Both men and women are affected; women are diagnosed more often, while men are more likely to develop the skin-thickening changes on the nose. People whose skin reacts strongly to sun, heat or emotional flushing may also be more susceptible.
How it is diagnosed
Rosacea is usually a clinical diagnosis, meaning a doctor can recognise it from the appearance and pattern of the skin and from your description of flushing and triggers. There is no specific blood test or scan for it. A GP, polyclinic doctor or dermatologist will look at where the redness and bumps occur and ask about how symptoms behave over time and what makes them worse.
Part of the assessment is ruling out conditions that can look similar, such as acne, seborrhoeic dermatitis, other forms of skin rash, or reactions to skincare. If the eyes are involved or the picture is unclear, a doctor may refer you to a dermatologist or eye specialist for further assessment.
Complications
Rosacea is not dangerous, but if left unmanaged it can cause problems that affect comfort, appearance and wellbeing:
- Eye involvement (ocular rosacea) — inflammation of the eyes and lids can cause persistent dryness, grittiness and irritation, and rarely can affect the surface of the eye if untreated.
- Skin thickening (rhinophyma) — long-standing rosacea can lead to thickened, enlarged skin on the nose, more commonly in men.
- Persistent redness and vessels — lasting redness and visible blood vessels that some people find hard to conceal.
- Emotional impact — because it affects the face, rosacea can affect confidence and mood, and some people feel self-conscious or anxious about flare-ups.
How it is treated
Treatment is tailored to the type and severity of rosacea, and usually combines good skincare with medical treatment. It aims to control symptoms and reduce flares rather than cure the condition.
- Gentle skincare and sun protection — mild, fragrance-free cleansers and moisturisers, and daily broad-spectrum sunscreen, form the foundation of care and help calm sensitive skin.
- Topical treatments — prescription creams and gels can reduce redness, bumps and inflammation. Some are designed to lessen visible redness, others to settle the inflamed spots.
- Oral treatments — for moderate cases, a doctor may prescribe oral medicines (including antibiotics used mainly for their anti-inflammatory effect rather than to treat infection).
- Laser and light treatments — these can target persistent redness and visible blood vessels that do not respond to creams.
- Eye treatment — ocular rosacea may need specific measures such as lid care or treatment guided by a doctor.
A doctor can advise which combination suits your skin, as treatments work best when matched to your particular pattern of rosacea and used consistently.
Living with rosacea and self-care
Alongside medical treatment, everyday habits make a real difference to how often and how badly rosacea flares:
- Know and avoid your triggers — use a flare diary to spot patterns, then limit the heat, foods, drinks or products that set you off.
- Keep skincare gentle — choose mild, fragrance-free products, avoid scrubbing or harsh exfoliants, and pat skin dry rather than rubbing.
- Protect against sun and heat — apply sunscreen daily, seek shade, wear a hat, and stay cool in Singapore’s climate.
- Choose cosmetics carefully — many people use green-tinted or gentle make-up to reduce the look of redness; introduce new products one at a time.
- Look after emotional wellbeing — stress is a common trigger, so managing stress and seeking support can help. If rosacea is affecting your confidence or mood, it is worth telling your doctor.
When to see a doctor
See a doctor for persistent facial redness, flushing or acne-like bumps that do not settle, so rosacea can be diagnosed and treated properly rather than mistaken for acne or simple sensitivity. You should also seek advice if your eyes become dry, gritty, red or irritated, as ocular rosacea benefits from early treatment, or if your nose skin is thickening. Getting the right diagnosis early makes rosacea easier to control and helps prevent complications.
Common questions
Is rosacea the same as acne?
No. Rosacea causes redness and flushing with bumps but no blackheads, and is treated differently, though the two can look similar.
Can rosacea be cured?
It cannot be cured but is well controlled with treatment and by avoiding triggers.
Does sun make rosacea worse?
Yes. Sun and heat are common triggers, so daily sun protection is important.
Can rosacea affect my eyes?
Yes. Rosacea can cause dry, gritty or irritated eyes and inflamed lids, sometimes before skin symptoms. Tell your doctor if your eyes are affected so this can be treated.
Will avoiding triggers stop flare-ups completely?
Not always, but identifying and reducing your personal triggers usually makes flares less frequent and less severe, especially alongside treatment.
