Patient ReportsRosacea: Symptoms, Causes, Diagnosis and Treatment
Written by Medicover Team and Medically Reviewed by Dr Girishma J , Dermatologists
Table of Contents
Rosacea is a common, chronic inflammatory skin condition that mainly affects the central face. It typically causes persistent redness, facial flushing, visible blood vessels and, in some people, acne-like bumps or pus-filled pimples. Some individuals may also develop eye symptoms or thickened skin, especially around the nose.
Rosacea often follows a pattern of flare-ups and remissions, with symptoms improving and then returning over time. Although there is no permanent cure, early diagnosis, proper skin care and appropriate treatment can help control symptoms, reduce flare-ups and improve quality of life.
What Are the Types of Rosacea?
Rosacea is classified into four main subtypes, although many people have features of more than one type.
- Erythematotelangiectatic Rosacea (ETR): Characterized by persistent facial redness, flushing and visible small blood vessels.
- Papulopustular Rosacea: Causes red, swollen bumps and acne-like pimples along with facial redness.
- Phymatous Rosacea: Leads to thickened, uneven skin, most commonly affecting the nose (rhinophyma).
- Ocular Rosacea: Affects the eyes and eyelids, causing irritation, redness and dryness.
What Are the Symptoms of Rosacea?
Rosacea symptoms vary depending on the subtype and severity. Many people experience episodes of worsening symptoms followed by periods of improvement.
Erythematotelangiectatic Rosacea (ETR)
- Persistent facial flushing and skin redness, especially across the cheeks, nose and forehead
- Visible tiny blood vessels (telangiectasia)
- Sensitive skin
- Burning or stinging sensation
- Dry, rough or flaky skin
- Mild facial swelling
Papulopustular Rosacea
- Acne-like red bumps and pus-filled pimples
- Persistent facial redness
- Sensitive skin
- Visible blood vessels
- Raised plaques in some individuals
Phymatous Rosacea
- Thickened, uneven skin texture
- Enlarged nose (rhinophyma)
- Enlarged skin pores
- Visible blood vessels
- Skin thickening affecting the chin, forehead, cheeks or ears in some cases
Ocular Rosacea
- Bloodshot eyes
- Watery eyes
- Burning, stinging or gritty sensation
- Dry, itchy eyes
- Light sensitivity
- Eyelid cysts or styes
- Blurred vision in severe cases
- Visible blood vessels along the eyelids
What Causes Rosacea?
The exact cause of rosacea remains unknown. Experts believe it develops due to a combination of genetic, immune and environmental factors.
- Abnormal Blood Vessel Function: Changes in facial blood vessels may contribute to flushing and persistent redness.
- Immune System Dysfunction: An exaggerated immune response may increase skin inflammation.
- Demodex Mites: People with rosacea often have higher numbers of Demodex folliculorum mites, although their exact role remains unclear.
- Helicobacter pylori Infection: Some studies suggest this bacterium may contribute to rosacea in certain individuals, but the relationship remains uncertain.
- Genetic Factors: A family history increases the likelihood of developing rosacea.
When to See a Doctor for Rosacea?
Consult a dermatologist if you develop persistent facial redness, repeated flushing, acne-like bumps or eye irritation that does not improve. Early diagnosis helps control symptoms, reduce flare-ups and prevent complications such as skin thickening or vision problems.
You should see a doctor if you have:
- Persistent facial redness lasting several weeks
- Visible blood vessels or acne-like bumps on the face
- Frequent burning, stinging or sensitive skin
- Eye redness, irritation or dry eyes with facial rosacea
Seek urgent medical attention if you develop:
- Sudden vision changes or blurred vision
- Severe eye pain or marked light sensitivity
- Rapid swelling around the eyes
Prompt treatment helps reduce the risk of long-term eye complications.

How Is Rosacea Diagnosed?
Rosacea is diagnosed mainly through clinical evaluation. There is no single laboratory test that confirms the condition.
Medical History
Your doctor will ask about your symptoms, flare-up triggers, skin care products, medications and family history.
Physical Examination
A dermatologist examines the pattern of facial redness, visible blood vessels, pimples and any eye involvement to distinguish rosacea from acne, lupus and other skin disorders.
Additional Tests
If another medical condition such as lupus is suspected, blood tests or additional investigations may be recommended.
How Is Rosacea Treated?
Treatment depends on the subtype, severity and individual symptoms. Most people require a combination of medication, skin care and trigger avoidance.
Topical Medications
- Metronidazole cream or gel
- Azelaic acid
- Ivermectin cream
- Brimonidine or oxymetazoline to reduce facial redness
Oral Medications
- Low-dose oral antibiotics such as doxycycline for inflammatory rosacea
- Oral isotretinoin in selected severe cases under specialist supervision
Laser and Light Therapy
Laser treatments and intense pulsed light (IPL) therapy can reduce visible blood vessels, persistent redness and some forms of skin thickening.
Surgical Treatment
Advanced phymatous rosacea causing thickened nasal skin (rhinophyma) may require laser resurfacing or surgical reshaping.
Eye Care
People with ocular rosacea may benefit from eyelid hygiene, artificial tears and medications recommended by an ophthalmologist.

What Are the Risk Factors for Rosacea?
Rosacea can affect anyone, but certain factors increase the likelihood of developing the condition.
- Age over 30 years
- Fair or easily sunburned skin
- Family history of rosacea
- Female sex (although severe phymatous rosacea is more common in men)
- Smoking
Can Rosacea Be Prevented?
Rosacea cannot be completely prevented, but avoiding known triggers can reduce flare-ups and improve long-term control.
Common triggers include:
- Sun exposure
- Hot or cold weather
- Emotional stress
- Heavy exercise
- Alcohol
- Hot beverages
- Spicy foods
- Hot baths or saunas
Living With Rosacea
Rosacea is a lifelong condition, but consistent treatment and skin care can help keep symptoms under control. Gentle cleansing, daily moisturising and regular use of broad-spectrum sunscreen are important parts of long-term management.
Keeping a symptom diary may help identify personal triggers. Working closely with a dermatologist allows treatment to be adjusted as symptoms change over time, helping maintain healthier skin and reduce flare-ups.
Frequently Asked Questions
1. How do I permanently get rid of rosacea?
There is no permanent cure for rosacea, but various treatments are available to help control the redness, bumps, and other symptoms associated with the condition. Your healthcare provider can recommend different types of medications, including topical treatments, to address acne, inflammation, and bacterial infections.
2. Does lack of B12 cause rosacea?
There are claims online that indicate a potential link between vitamin deficiencies, specifically B vitamins such as B-12, and the development of rosacea. However, it is important to note that excessive intake of certain vitamins can exacerbate the symptoms of rosacea.
3. Is it okay to put makeup over rosacea?
It's safe to apply makeup over rosacea, just be cautious with the products you use. Opt for a green-tinted base to help neutralize redness and create a more even skin tone. Look for a primer with UVA/UVB protection to protect your skin from further irritation.
4. Why is my rosacea so itchy?
Having rosacea can weaken the skin's protective barrier, making it more prone to irritation and itching. Itchiness in rosacea can also be triggered by environmental factors such as temperature changes, certain skincare products, or exposure to allergens.
5. How do you stop rosacea from spreading?
Here are some tips to prevent rosacea flare-ups: Stay in the shade to avoid direct sunlight. Be mindful of sun protection as even a short exposure to sunlight can trigger flushing and redness. Try to reduce stress levels. Avoid getting overheated. Consider cutting back on hot beverages. Be aware of how alcohol affects your skin. Limit spicy foods in your diet. Choose skin and hair care products that are suitable for rosacea. Use makeup that is gentle on rosacea-prone skin.
