Rosacea

Root Causes

Rosacea is a chronic inflammatory condition that affects the skin, blood vessels, immune system, and nervous system. Research suggests that people with rosacea have heightened sensitivity in the facial blood vessels and immune system, causing exaggerated responses to otherwise normal triggers. This can lead to flushing, redness, visible blood vessels, and inflammatory bumps. Studies have also found associations between rosacea and changes in the gut microbiome, digestive disorders, and increased inflammatory activity. Rather than being simply a cosmetic concern, rosacea involves complex interactions between the skin, immune system, nervous system, and gut.

Triggers

Rosacea symptoms are often triggered by factors that increase blood vessel dilation or activate inflammatory pathways. Common triggers include sunlight, heat, spicy foods, alcohol, exercise, emotional stress, hot beverages, and certain skincare products. These triggers can cause increased blood flow to the face, leading to redness and flushing. Because triggers vary widely between individuals, identifying personal patterns is often one of the most effective strategies for reducing flare-ups and improving long-term symptom control.

Healing

Supporting rosacea involves reducing inflammation, protecting the skin barrier, and minimizing exposure to personal triggers. Gentle skincare, sun protection, stress management, and dietary modifications may all help reduce flare-ups. Addressing gut health can help calm symptoms quicker as well as create lasting relief. A personalized approach often produces the best results, as triggers and contributing factors can vary widely.

Frequently Asked Questions

  • Yes. Research has found higher rates of digestive conditions and gut microbiome changes in people with rosacea. Scientists believe that communication between the gut, immune system, and skin may influence inflammation and symptom severity.

  • Hormones are not considered a primary cause of rosacea, but hormonal changes can influence symptoms. Many people notice worsening redness and flushing during menopause, periods of stress, or other times when hormones fluctuate. Hormones may act as a trigger rather than the underlying cause.

  • Several studies have found a higher prevalence of Small Intestinal Bacterial Overgrowth (SIBO) in people with rosacea. Some research has even shown improvements in rosacea symptoms after successful treatment of SIBO. While not everyone with rosacea has SIBO, it may be worth investigating.

  • The best products for rosacea are gentle, fragrance-free, and designed to support the skin barrier. Harsh exfoliants, strong acids, and heavily fragranced products often worsen symptoms.

  • Reducing facial redness often involves identifying personal triggers and minimizing inflammation. Sun protection, gentle skincare, stress management, avoiding known trigger foods, and protecting the skin barrier can all help reduce flushing and irritation over time.

  • Rosacea flare-ups are often triggered by changes in stress levels, weather, sun exposure, skincare products, alcohol, spicy foods, illness, or hormonal changes. Sometimes several triggers occur together, leading to a sudden worsening of symptoms.

  • Research suggests that genetics play a role in rosacea. People with a family history of rosacea are more likely to develop the condition themselves. However, genetics alone do not determine whether symptoms occur, and environmental triggers also play an important role.

  • Common food triggers include alcohol, spicy foods, hot beverages, and foods that cause flushing. However, triggers vary widely from person to person. I recommend keeping a symptom journal or food dairy to help identify which foods may be contributing to your individual flare-ups.
