Synopsis
Recognise overlapping vascular, inflammatory, ocular and phymatous rosacea features across skin tones, exclude important mimics, and select phenotype-directed skin care, topical, systemic and referral options.
- Diagnose by features rather than rigid subtypes: persistent centrofacial erythema, flushing, telangiectasia, papules or pustules, ocular disease and phymatous change overlap.
- Comedones are not a rosacea feature; their presence suggests acne coexistence or an alternative diagnosis.
- In darker skin, persistent erythema may appear dusky, violaceous or brown and is often detected more reliably through warmth, burning, swelling, photographs and dermoscopy.
- Ask every patient about gritty, dry, burning or red eyes, lid crusting, recurrent styes, pain, photophobia and altered vision.
- Use gentle non-perfumed skin care and daily broad-spectrum SPF 30 or higher; identify personal triggers through a diary instead of prescribing universal avoidance.
- Papulopustular disease can be treated with topical ivermectin, azelaic acid or metronidazole; systemic modified-release doxycycline is an option when inflammatory burden warrants it.
- Persistent erythema responds differently from papules: camouflage, a carefully tested vasoconstrictor, vascular laser or light treatment may be considered according to expertise and skin type.
- Established rhinophyma and other phymatous change need dermatology or procedural assessment; escalating antibacterial therapy will not remove fibrotic bulk.
Key red flags
Eye pain, photophobia, reduced vision, marked corneal redness, rapidly progressive facial swelling, systemic illness or an atypical scarring or photosensitive eruption needs urgent ophthalmic or diagnostic assessment rather than routine rosacea treatment.
Eye pain, photophobia, reduced acuity or corneal opacity suggests keratitis or ulceration and requires urgent same-day ophthalmic assessment.
Investigation priorities
Document dominant phenotype, severity and urgent ocular findings.
Management branches
Facial papules or pustules occur without comedones and without sight-threatening ocular features.
- Start gentle cleanser, non-comedogenic moisturiser and SPF 30 or higher, remove inappropriate facial corticosteroid exposure through a planned approach, and agree one topical anti-inflammatory option.
- Use ivermectin once daily, azelaic acid twice daily or metronidazole twice daily according to the chosen product; apply away from eyes and set the product-specific response point.
- For more extensive or resistant inflammation, consider modified-release doxycycline and review after a defined course; reassess diagnosis if there is no meaningful response.
Persistent lid or eye symptoms, corneal warning features or established tissue thickening is present.
- Assess visual symptoms, acuity and ocular surface; give lid-hygiene and lubricating advice for uncomplicated symptoms while arranging clinical review.
- Seek same-day ophthalmology for pain, photophobia, visual change or corneal abnormality and do not rely on a skin topical to protect sight.
- Refer phymatous change for dermatology and procedural options such as laser, electrosurgery or excision after inflammatory activity is assessed.
