Rosacea treatment with 532 nm KTP versus 595 nm pulsed dye laser—A prospective, controlled study

Background Pulsed‐dye lasers (PDL) are one of the standard therapies for rosacea, but alternatives are needed. Aims To compare the efficacy and safety of the variable‐sequenced, large‐spot 532 nm KTP laser to the 595 nm PDL in treating rosacea. Materials and Methods A prospective, controlled, evaluator‐blinded study. Patients were treated with either a KTP or PDL with 1–3 sessions at intervals of 6–8 weeks. A follow‐up visit was scheduled on Week 6 post‐treatment. Clinical outcome was assessed by computer‐assisted analysis and by patients and two blinded dermatologists. Pain intensity during treatment and adverse events were documented. Results Forty‐five patients (mean age 51 years) were allocated in a 2:1 ratio to either the KTP or PDL. Erythema in both treatment arms decreased significantly (p
