Rosacea is a chronic inflammatory skin condition, not simple sensitivity. It has specific triggers, documented mechanisms and actives that modulate it. The problem is that many skincare products — including some sold specifically for sensitive skin — contain ingredients that exacerbate rosacea. Understanding the difference is the first step.

What Rosacea Is (and What It Isn't)

Rosacea isn't generic sensitive skin. It's a chronic inflammatory condition of the dermis characterised by abnormal vasodilation, exaggerated neuroinflammatory response and, in some subtypes, bacterial proliferation (Demodex folliculorum). The main subtypes have different manifestations and treatments:

• ETR (erythematotelangiectatic) — redness, flushing, visible telangiectasias
• Papulopustular — papules and pustules, different from acne (no comedones)
• Ocular — affects eyelids and conjunctiva

What Should Never Be in a Rosacea Routine

• Synthetic fragrances and essential oils (menthol, eucalyptus, high-concentration lavender) — potent vasodilators
• Denatured alcohol in the first 5 ingredients
• AHAs at high concentrations — aggressive chemical exfoliation increases erythema
• Pure vitamin C (ascorbic acid) — very acidic pH can aggravate
• Physical exfoliants — microtrauma that reactivates inflammation

What Helps With Evidence

• Niacinamide at 2–4% — anti-inflammatory, reduces erythema, reinforces barrier
• Prebiotics — balance the microbiome imbalanced in papulopustular rosacea
• Ceramides — replenish the compromised barrier characteristic of rosacea
• Mineral SPF — UV exposure is one of the main triggers
