Rosacea is a skin condition that makes your face look red and sometimes swollen. It often shows up on the cheeks, nose, chin, and forehead. Many people wonder what causes rosacea. The truth is, doctors do not know the exact cause. But they believe many things may play a part. This article will explain what causes rosacea in simple words.
What Is Rosacea?
Rosacea is a long-lasting skin problem. It causes redness and small bumps on your face. The skin can also feel warm or sting. Sometimes, your eyes may look red or dry. Rosacea usually starts after age 30. It affects more women than men, but men can get it too.
What Are the Signs of Rosacea?

- Visible small blood vessels on the face
- Small, red, pus-filled bumps
- Burning or stinging feeling on the skin

What Causes Rosacea?
Doctors do not know one clear cause. Instead, many things may cause rosacea. These things can make blood vessels in your face larger. This causes redness and swelling. Let’s look at the main causes.
1. Genetics
If your family has rosacea, you may get it too. Genes can make your skin more sensitive. This means your face can get red more easily.
2. Blood Vessel Problems
Rosacea is linked to blood vessels in the face. These vessels can get bigger and cause redness. When they stay big for a long time, rosacea happens.
3. Immune System
Your immune system helps fight sickness. But sometimes, it can overreact. This may cause inflammation, which is redness and swelling. This can lead to rosacea symptoms.
4. Bacteria And Mites
Some tiny mites live on your skin. Most people do not have problems with them. But people with rosacea often have more mites. Also, a bacteria called Helicobacter pylori in the stomach may play a role. These can cause inflammation and redness.
5. Sun Exposure
Sunlight can hurt your skin. It can make blood vessels bigger. Too much sun can cause rosacea to flare up. Protecting your skin from the sun helps a lot.
6. Weather Changes
Hot, cold, windy, or humid weather can trigger rosacea. Sudden changes in weather make blood vessels react. This brings redness and irritation.
7. Hot Drinks And Spicy Foods
Hot coffee, tea, or spicy meals can cause flushing. This means your face turns red quickly. These foods make blood vessels open wide.
8. Alcohol
Drinking alcohol, especially red wine, can make rosacea worse. Alcohol widens blood vessels and causes redness.
9. Stress And Emotions
Feeling stressed, angry, or embarrassed can cause flushing. These emotions affect the nervous system. This makes blood vessels open and skin turn red.
10. Exercise
Physical activity raises your body temperature. This makes blood flow faster. Your face may get red and hot. This can trigger rosacea flare-ups.
11. Medications
Some medicines make blood vessels bigger. These include some blood pressure drugs and steroids. They can cause or worsen rosacea.
