What are the four rosacea subtypes?

ETR (erythematotelangiectatic): persistent central erythema, telangiectasia, flushing; PPR (papulopustular): inflammatory papules/pustules on erythematous background; Phymatous: skin thickening, rhinophyma; Ocular: lid margin inflammation, conjunctival injection, corneal involvement.

What topical treatments target PPR rosacea?

Ivermectin 1% cream (once daily) is first-line for PPR; azelaic acid 15% gel alternative; metronidazole 0.75-1% for maintenance; brimonidine 0.33% gel for persistent erythema (ETR); ivermectin superior to metronidazole in head-to-head trials.

What dose of doxycycline treats rosacea?

Modified-release doxycycline 40 mg/day (sub-antimicrobial, anti-inflammatory dose) is FDA-approved for PPR rosacea; as effective as 100 mg/day for rosacea with no antibiotic selection pressure; treatment course 3-6 months.

When is systemic isotretinoin used for rosacea?

Low-dose isotretinoin 10-20 mg/day (0.1-0.3 mg/kg/day) for refractory PPR or phymatous rosacea; reduces sebaceous gland size and skin thickness in rhinophyma; response maintained for years post-treatment; requires iPLEDGE monitoring as for acne.

What laser/IPL treatments address different rosacea subtypes?

IPL (intense pulsed light) for ETR and telangiectasia; pulsed dye laser (PDL) 595 nm for telangiectasia and persistent erythema; CO2 laser for rhinophyma (phymatous); all laser treatments require adequate sun protection pre/post-treatment.
