Why does rosacea cause sensitive skin?

Rosacea-related sensitivity may feel like burning, stinging, warmth, tightness or tenderness. Water, cleanser, moisturiser, cosmetics, wind, heat and sunlight can provoke symptoms even when the skin looks only mildly flushed. Inflammation around small blood vessels and surface nerves can make sensations more noticeable. A disrupted barrier also allows moisture to escape more easily and makes irritants reach sensitive nerve endings. Sensitive skin is a common presentation of Rosacea, but sensitivity can also occur with eczema, contact irritation or other conditions, so the sensation alone cannot identify its cause.

Use lukewarm water and a mild, fragrance-free cleanser; wash with fingertips rather than a cloth or scrub. Apply a plain moisturiser while the skin is still slightly damp, and introduce one new product at a time. Broad-spectrum sun protection, shade and a hat can reduce ultraviolet and heat-related flares. Keep a short trigger diary for heat, spicy foods, alcohol, stress, products and weather changes. A clinician can distinguish rosacea from another facial rash and choose treatment that matches flushing, bumps or persistent irritation.

Arrange an assessment if sensitivity persists, interferes with washing or applying products, or comes with frequent flushing, facial bumps or visible vessels. Seek prompt care for eye pain, light sensitivity, blurred vision, marked eyelid swelling or a sudden severe facial reaction. These features can need attention beyond routine skin-care changes.

Could rosacea explain my burning or stinging, or should we check for contact dermatitis? Which cleanser, moisturiser and sunscreen ingredients are least likely to irritate me? Do my eye symptoms need a separate examination? What should I use during a flare, and how long should I try it before returning for review?
