Rosacea is a common, chronic skin condition that primarily affects the face. It is characterized by redness, bumps, and pustules on the face, which can worsen over time. Rosacea usually develops after the age of 30. In Germany, about 2-5% of all adults are affected.
Although rosacea can occur in both genders, it is more common and severe in women. Studies have shown that women between 30 and 50 years old are most frequently affected by rosacea. Symptoms in women can be more pronounced and may lead to a significant reduction in quality of life.
Symptoms of Rosacea
Rosacea primarily affects the face, especially the cheeks and nose. These areas are often red. Initially, these redness episodes usually occur in flare-ups until they eventually become persistent. As the condition progresses, the blood vessels in the facial skin can be seen as a fine network on the affected areas. The blood vessel dilations become visible because they are widened by rosacea. Skin inflammation causes bumps (papules) and pus-filled pimples (pustules) that resemble acne. In particular, men may develop a nodular thickening of the nose, colloquially known as “bulbous nose.”
Causes of Rosacea
The exact causes of rosacea are not fully understood, but it is believed that a combination of genetic and environmental factors plays a role. Possible environmental factors that can trigger rosacea include:
- Sunlight
- Hot beverages
- Hot baths
- Stress
- Hormonal changes
- Certain foods such as coffee, alcohol, and spices
Although pus-filled pustules can develop in rosacea, it is not a form of acne. Unlike acne, skin oil production is not increased in rosacea. It is also suspected that certain microorganisms, such as the Demodex mite on the face and in the gut, may play a role in the development of rosacea.
Diagnosis and Treatment of Rosacea
Treatment of rosacea depends on the severity of symptoms and can range from topical medications like corticosteroids or antibiotic creams to oral medications or light therapy. Lifestyle changes, including a balanced diet and stress reduction, can also help improve symptoms. However, rosacea usually cannot be cured, only managed. Regular check-ups with a dermatologist are important to monitor symptoms and adjust treatment if necessary. Overall, it is important to be proactive with rosacea and take care of skin health. Early diagnosis and treatment can help alleviate symptoms and prevent serious complications.
Skin Flora: Rosacea Alters the Skin Microbiome
In addition to known triggers, the role of the microbiome in the development and worsening of rosacea is of increasing interest. There is some evidence that the microbiome (the totality of microorganisms living on and in our bodies) may play a role in rosacea. A disturbed microbiome, showing unfavorable changes in bacterial species and numbers, can impair the immune system and thus intensify inflammatory reactions in the skin. Some studies have shown that people with rosacea have a different microbiome composition compared to those without the condition. A connection between Demodex mites and rosacea has been observed, as studies have shown that people with rosacea have a higher density of these mites on their skin. It is suspected that an overpopulation of Demodex mites can lead to skin inflammation, which is a symptom of rosacea.
Causes of Rosacea: The Gut Can Also Play a Role
Besides the influence of the skin microbiome, studies have shown that the development of rosacea is also linked to the gut. A disturbed gut, especially dysfunction in the gut flora, can impair the immune system and lead to skin inflammation. Some studies have shown that people with rosacea have a compromised gut barrier, suggesting that a disturbed gut may play a role in the development of rosacea.
Tip: Special Foods to Watch for with Rosacea
There is also evidence that diet can influence the development and worsening of rosacea. Some studies have shown that certain foods and drinks can trigger or worsen rosacea symptoms.
These include, for example:
- Dairy products such as yogurt, cheese, sour cream
- Specific fruits: citrus fruits, bananas, red plums, figs
- Spicy foods
- Foods rich in histamine
- Beverages: alcohol, especially red wine, beer, bourbon, gin, vodka, and champagne.
- Hot drinks like coffee.
It is important to note that the effects of diet on rosacea can vary from person to person. Some people can eat certain foods without problems, while others are more sensitive to specific foods.
New Approach: A Healthy Gut Flora
A balanced diet rich in fiber can help support the gut microbiome and maintain a healthy gut flora. Additionally, some studies show that certain probiotic supplements can improve rosacea symptoms. New treatment approaches for rosacea increasingly include pro- and prebiotics, as they have been shown to benefit the gut flora and help restore its balance.
