What is Rosacea?
Rosacea is a long-lasting inflammatory skin condition that primarily affects the face. It is marked by redness, irritated skin, and small bumps filled with pus. Often confused with acne, eczema, or skin allergies, rosacea is non-contagious. Research suggests that rosacea impacts between 1% and 20% of individuals, though the true prevalence might be higher due to frequent misdiagnoses where symptoms are attributed to other conditions1. More common in women2, rosacea typically begins between the ages of 30 and 50 and is most prevalent among individuals with fair skin, light hair, and blue eyes3. While no permanent cure exists, there are various treatments that can help manage the symptoms of rosacea.
Symptoms and Types of Rosacea
Rosacea can be classified into four types, each with its own distinct symptoms4. However, a common sign across all types is flushed or red skin paired with pus-filled bumps. It’s also possible for a person to experience more than one type of rosacea simultaneously.
Erythematotelangiectatic Rosacea (ETR)
The most common form, ETR is characterized by redness, flushed skin, and tiny, visible blood vessels that resemble spider veins. The skin may become sensitive, dry, and rough.
Papulopustular Rosacea
This type, often found in middle-aged women, closely resembles acne. It typically causes oily skin and significant redness.
Phymatous Rosacea
This form leads to thickening of the skin, particularly on the nose, along with large pores and bumpy texture. It most often affects men and is usually found alongside other rosacea types.
Ocular Rosacea
Affecting the eye area, ocular rosacea can lead to symptoms such as dry eyes, irritation, swollen eyelids, and in some cases, blurry vision or sensitivity to light. Around 50% of people with rosacea experience eye-related symptoms.
What Causes Rosacea?
While the exact cause of rosacea remains unknown, it is generally thought to be triggered by a mix of genetic and environmental factors. Many individuals with rosacea have a family member who also suffers from the condition. There are several factors6,7,8 that may either trigger rosacea or worsen its symptoms, including:
- Sun exposure
- Hot weather or overheating, especially when in bed
- Physical activity or exercise
- Hot baths or showers
- Stress and anxiety
- Alcohol consumption
- Drinking hot beverages
- Eating spicy foods
- Foods that contain cinnamaldehyde (such as cinnamon, chocolate, tomatoes, and citrus fruits)
- The presence of the bacterium Helicobacter pylori in the intestines
- Certain medications, particularly those that expand blood vessels, like blood pressure drugs
- Some cosmetics and skincare products
In addition, research suggests that individuals with rosacea may have heightened sensitivity to a skin mite called Demodex folliculorum, which lives in the pores. When these mites die, they release bacteria into the skin, potentially triggering an immune response that leads to redness and inflammation. People with rosacea tend to have more than four times as many Demodex mites in their skin compared to those without the condition9. Keeping a record of your symptoms in a journal can be helpful for identifying specific triggers, allowing you to avoid those that cause flare-ups.
How is Rosacea Treated?
Since there is no cure for rosacea, treatment focuses on minimizing and managing the symptoms. If left untreated, the condition can worsen over time10. Common treatments for rosacea may include:
- Creams and lotions designed to reduce skin inflammation and discoloration
- Over-the-counter (OTC) and prescription eye drops to alleviate ocular rosacea symptoms
- Oral antibiotics to manage inflammation and eye-related symptoms
- Potent acne medications, which may cause side effects
- Laser therapy to reduce visible blood vessels or remove thickened skin
Additionally, understanding and avoiding your personal triggers is a crucial step in managing the condition effectively.
When to See a Doctor
If you experience persistent redness on your face or any of the other symptoms mentioned earlier, it is important to see your doctor. A proper diagnosis is essential to differentiate rosacea from other skin conditions, ensuring you receive the appropriate treatment. Your doctor may refer you to a dermatologist, a specialist in skin disorders. If left untreated, rosacea may worsen and lead to complications such as conjunctivitis (inflammation of the eye’s membrane) or rhinophyma, a condition where tissue builds up around the nose due to enlarged sebaceous glands.
