Introduction: Rosacea Is More Than Skin Deep

Rosacea is often dismissed as a cosmetic issue—persistent redness, flushed cheeks, or visible blood vessels. But this chronic condition is much more than a surface-level problem. At its core, rosacea is an inflammatory skin disorder that reflects deeper dysfunction within the immune system, gut, and vascular network.

If you’ve tried creams, antibiotics, or laser treatments without long-term relief, it’s time to look beneath the surface. In functional and integrative medicine, we view rosacea as a whole-body condition—one that can often be improved by addressing inflammation at the root.

What Is Rosacea?

Rosacea is a chronic inflammatory skin condition that typically affects the central face—especially the nose, cheeks, chin, and forehead. It’s most common in fair-skinned adults over 30 and tends to progress without intervention.

Common signs and symptoms include:

• Persistent redness (erythema)
• Flushing or blushing easily
• Visible blood vessels (telangiectasia)
• Bumps or pimples (similar to acne)
• Thickened skin, especially around the nose (rhinophyma)
• Burning, stinging, or sensitivity
• Dry, irritated eyes (ocular rosacea)

Rosacea often flares in cycles, triggered by environmental, dietary, and emotional factors. But the common thread among all cases? Chronic inflammation.

Rosacea as an Inflammatory Disorder

The hallmark feature of rosacea is persistent inflammation of the skin, driven by an overactive immune response and vascular instability. Instead of reacting normally to stimuli, the skin in rosacea becomes hyper-reactive to:

• Sunlight
• Heat or cold
• Spicy foods
• Alcohol
• Stress
• Skin products
• Microbes (like Demodex mites)

This hypersensitivity reflects an imbalance in immune regulation, not just skin sensitivity.

What Drives Inflammation in Rosacea?

Functional medicine aims to understand why inflammation occurs in the first place. Here are key contributors:

1. Dysregulated Immune Response

Rosacea is associated with innate immune system overactivation. This leads to:

• Excess release of inflammatory peptides like cathelicidin and kallikrein 5
• Increased blood vessel dilation and permeability
• Chronic redness and sensitivity

Instead of protecting the skin, the immune system overreacts—causing inflammation, tissue damage, and visible symptoms.

2. Microbial Imbalance (Demodex and Skin Dysbiosis)

People with rosacea often have higher levels of Demodex mites, which live in hair follicles and sebaceous glands. These mites can:

• Stimulate immune activation
• Trigger inflammation via bacterial byproducts
• Worsen pustules and skin sensitivity

In addition, the skin microbiome may become unbalanced, allowing pro-inflammatory bacteria to dominate. Restoring a healthy skin barrier and microbial balance is key to calming flares.

3. Gut-Skin Axis and Leaky Gut

Research strongly links rosacea to gut inflammation and gastrointestinal disorders, such as:

• Small Intestinal Bacterial Overgrowth (SIBO)
• Irritable Bowel Syndrome (IBS)
• Leaky gut (increased intestinal permeability)

The gut-skin axis explains how gut dysfunction triggers skin inflammation through:

• Systemic immune activation
• Histamine release
• Toxin leakage into the bloodstream
• Nutrient malabsorption (e.g., zinc, B vitamins)

A 2008 study found that treating SIBO in rosacea patients led to marked improvement or remission, emphasizing the need to treat the gut to heal the skin.

4. Food Sensitivities and Inflammatory Diets

Certain foods are known rosacea triggers, especially:

• Alcohol (especially red wine)
• Spicy foods
• Sugar and refined carbs
• Dairy
• Gluten

These foods may increase histamine, spike blood sugar, or trigger immune responses in susceptible individuals—worsening skin inflammation.

5. Oxidative Stress and Mitochondrial Dysfunction

Oxidative stress—caused by free radicals and poor antioxidant defense—damages skin cells and blood vessels. In rosacea, this leads to:

• Faster skin aging
• Heightened redness
• Poor wound healing

Mitochondrial dysfunction may also play a role in skin sensitivity and decreased energy availability for repair processes.

6. Hormonal Imbalance and Stress

Hormones like cortisol (stress), estrogen, and androgens influence inflammation, sebum production, and immune regulation.

Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis, leading to:

• Cortisol dysregulation
• Immune dysfunction
• Heightened skin reactivity

Functional medicine supports stress regulation as part of any inflammatory skin treatment.

The Functional Medicine Approach to Rosacea

Instead of masking symptoms with antibiotics or steroids, functional medicine uses a root-cause strategy that includes:

1. Comprehensive Testing

To identify the hidden causes of inflammation, we may run:

• Gut microbiome and SIBO testing
• Food sensitivity testing
• Nutrient panels (zinc, B12, antioxidants)
• Hormone and cortisol testing
• Inflammatory markers (CRP, homocysteine, histamine levels)

2. Anti-Inflammatory Nutrition

We tailor a gut-healing, low-inflammatory diet that may include:

• Elimination of gluten, dairy, alcohol, and sugar
• Abundant omega-3s (salmon, flaxseed, walnuts)
• Colorful antioxidant-rich vegetables
• Zinc, vitamin A, and polyphenol-rich foods (green tea, turmeric)

3. Targeted Supplementation

Supplements that support skin healing and immune modulation include:

• Zinc carnosine – for gut and skin barrier repair
• Probiotics and prebiotics – to balance the microbiome
• Omega-3 fatty acids – reduce inflammation and redness
• Vitamin D3 + K2 – modulates immune response
• Quercetin and bromelain – natural antihistamines and mast cell stabilizers
• NAC or glutathione – antioxidant defense

4. Topical and Regenerative Support

We may incorporate:

• Gentle barrier-repair skincare (niacinamide, ceramides)
• Red light therapy to reduce inflammation and promote healing
• Platelet-Rich Fibrin (PRF) or microneedling to improve skin texture and reduce visible vessels
• Natural anti-inflammatories like green tea extract or azelaic acid

5. Stress Reduction and Nervous System Balance

We help calm internal triggers using:

• HRV biofeedback
• Breathwork and meditation
• Adaptogens (ashwagandha, holy basil)
• Sleep optimization

Real Healing Starts from Within

While conventional rosacea treatments can reduce visible redness temporarily, they don’t address why your skin is inflamed in the first place. Topical creams and antibiotics may bring temporary relief, but they often leave patients dependent and frustrated when flares return.

Functional medicine offers a deeper solution by identifying and correcting the biological imbalances driving inflammation—from the gut to the immune system to the skin barrier.

At Sheen Vein & Cosmetics, we treat rosacea from the inside out. Our functional medicine programs focus on restoring gut health, reducing inflammation, and rebalancing the immune system—so your skin can heal naturally and glow from within.
