Rosacea and couperose in Belgium: drinks that worsen redness and INTI ginger as an anti-inflammatory

Pathophysiology of rosacea and nutrition

Rosacea is a chronic inflammatory vascular skin condition:

• Vascular hyperreactivity: facial blood vessels have an exaggerated sensitivity to thermal, emotional, and dietary stimuli → flush (sudden redness) → persistent erythema
• TRPV4 and spices: highly undiluted ginger can activate TRPV4 in keratinocytes → flush — therefore, DILUTED INTI is preferred for rosacea patients
• NF-κB and VEGF: low-grade inflammation (NF-κB ↑) stimulates VEGF → neovascularization → telangiectasias (permanent red vessels)
• Demodex folliculorum: overpopulation of skin mites → cathelicidin LL-37 → inflammation → redness exacerbated by histamine-rich fermented foods
• Gut microbiome: dysbiosis → ginger SIBO frequent in rosacea → intestinal histamine → systemic flush

Drinks and rosacea: nutritional triggers

Mechanisms of curcumin and gingerol in rosacea

• Curcumin → NF-κB ↓ → VEGF ↓: curcumin inhibits NF-κB → VEGF ↓ → less neovascularization → fewer progressive telangiectasias
• Curcumin → LL-37 ↓: curcumin reduces the expression of cathelicidin LL-37 (central in rosacea) via TLR2 inhibition → reduction of inflammatory flares
• Gingerol → microbiome: prebiotic → improved gut microbiome → reduced SIBO → less intestinal histamine → less systemic flush
• Important: INTI cold and diluted: heat activates TRPV4 → flush. DILUTED COLD INTI (1 shot in 150–200ml cold water) achieves a gingerol concentration below the threshold. Most rosacea patients tolerate diluted cold INTI. Test individually starting with small doses.
